<span style="font-family: "arial" , "helvetica" , sans-serif;">Equipamento: Teclado musical Casio CTK-700</span></div>
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">Problema: Algumas teclas não funcionam após alguns anos sem uso.</span></div>
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span></div>
<div style="text-align: justify;">

<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">Os teclados Casio são bem famosos e populares como linha de entrada e até mesmo profissional. Possuem bom custo/benefício e dificilmente necessitam de manutenção. Porém as vezes algumas ações comprometes a vida útil desses teclados como o desse caso.</span></div>

<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">Este teclado é de um amigo que o ganhou e pediu uma avaliação do motivo das teclas não funcionarem.</span></div>
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">O primeiro passo foi ligar o teclado e ver quais teclas não funcionavam o que mostrou que as teclas da região central não funcionavam, porém todo o restante estava em perfeitas condições.</span></div>
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">Ao desmontar o teclado vi que a placa principal nada havia sofrido, isso visualmente, não haviam marcas de componentes queimados ou falhas na PCI.</span></div>
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">Fui então desmontar a seção das teclas, e estas sim estavam em péssimas condições.</span></div>

<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">Havia muita sujeira e também oxidação em trilhas, terminais e componentes o que tornava a situação desta placa irreversível.</span></div>

<span style="font-family: "arial" , "helvetica" , sans-serif;">Problema: O equipamento apesar de ligar tinha somente som em uma única caixa, toca discos travado e rádio sem sintonia.</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">Os rádios Teleunião reinaram nas décadas de 50 e 60, sendo caros e bem raros de serem vistos nos lares da época. </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">O rádio reparado pertence a um amigo e está em posse da família desde que foi comprado em 1961. </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">O rádio antes da restauração possuía esta aparência:</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>

<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span><span style="font-family: "arial" , "helvetica" , sans-serif;">O primeiro desafio foi entender como uma válvula eletrônica funciona, pesquisando na internet algumas coisas começaram a ficar claras, como os termos utilizados, as ligações de polarização, uso, e o princípio de funcionamento.</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">Por sorte dentro do rádio havia um esquema parcialmente legível e que ao final complementei com as medições realizadas:</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEitCSF8q4NL3hCIOSJvOk75CnO9MQcKnxFbLM5_LZfXTLCGubVgY4N3jEmDcpC19VVUB7L4WRJMszKeLKKnJSTVwzu5QOlE2LRl3MjdQL5lVpEWtl8UyUJq996iHxVtg29e1T6ceXnbUg/s1600/Esquema+Final.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="253" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEitCSF8q4NL3hCIOSJvOk75CnO9MQcKnxFbLM5_LZfXTLCGubVgY4N3jEmDcpC19VVUB7L4WRJMszKeLKKnJSTVwzu5QOlE2LRl3MjdQL5lVpEWtl8UyUJq996iHxVtg29e1T6ceXnbUg/s400/Esquema+Final.jpg" width="400" /></a></div>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">Em posse do esquema começaram as identificações dos modelos das válvulas, medições, de tensão dos filamento de aquecimento, correntes de <i>bias</i> e continuidade das ligações internas além da limpeza e lubrificação dos potenciômetros.</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">Durante as conversas com várias pessoas conhecedoras de restauração de rádios antigos, foi recomendado a troca dos capacitores sólidos do rádio (crédito ao Sr. Meyer da radiolandia@gmail.com) e é espantoso como a tecnologia de fabricação dos capacitores evoluiu, pois o tamanho reduziu consideravelmente para uma mesma tensão de isolação. Substituídos os capacitores a recepção passou a dar sinais de vida.</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span><span style="font-family: "arial" , "helvetica" , sans-serif;">Continuando o trabalho, o diagnóstico do canal que não funcionava não podia ser pior... a válvula da etapa final de potência estava queimada e o transformador estava com o enrolamento primário aberto.</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">Na foto é possível ver o transformador, a válvula da etapa final e a etapa de pré-amplificação à direita.</span><br />

<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">E agora, onde conseguir alguém que produza transformadores para um rádio com mais de 50 anos de existência? Por sorte encontrei uma grande ajuda com o Sr. </span><span style="background-color: white; color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">Alexandre Simionovski da <a href="http://schatz.eng.br/" target="_blank">Transformadores Schatz</a>, que foi extremamente atencioso quanto a análise da peça que enviei e para sanar todas as dúvidas que haviam quanto a confecção das novas peças visto que a saída deste tinha uma particularidade de haverem dois enrolamentos isolados, um para o alto-falante grande e outro para outros dois alto-falantes pequenos de médio e agudo.</span></span><br />
<span style="background-color: white; color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span></span>
<span style="background-color: white; color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">Na imagem é possível ver os dois novos transformadores que devido algumas alterações de carcaça ficaram montados alinhados mas com excelente fixação no chassi do rádio.</span></span><br />

<span style="background-color: white; color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">Durante a confecção do transformadores foi adquirido a válvula para substituição do modelo <a href="https://drive.google.com/open?id=0ByhJDqX7PgfXM0JjUk1PaTdEMWs" target="_blank">EL84</a> através do mercado livre.</span></span><br />
<span style="background-color: white; color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span></span>
<span style="background-color: white; color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">Ao instalar a nova válvula esta aqueceu acima do normal e ao medir a corrente de <i>bias</i> identifiquei que estava muito acima do normal, o que em pouco tempo provocaria a queima da mesma. </span></span><br />
<span style="background-color: white; color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">Em buscas por explicações na internet vi vários relatos de que é normal no início da vida da válvula esta apresentar características diferentes porém as que eu estava vivenciando estavam muito distantes do que estava descrito no esquemático e comparado com o canal ainda original do rádio. </span></span><br />
<span style="background-color: white; color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">Após muitas horas de análise não tive escolha senão readequar a polarização da válvula fazendo com que a corrente que por ela fluía estivesse dentro do especificado pelo datasheet. Após isto o aquecimento excessivo foi sanado além do som ficar equilibrado entre as caixas direita e esquerda.</span></span><br />
<span style="background-color: white; color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span></span>
<span style="background-color: white; color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">Outros pontos de conserto se seguiram como montar a entranhada corda do sintonizador que demandou muito tempo até conseguir um funcionamento adequado e com tensionamento correto.</span></span><br />

<span style="background-color: white; color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">O toca-discos também necessitou de reparos, pois após tantos anos sem uso a graxa secou e emperrou todos os mecanismos. Após um desmonte completo e remontagem com óleo de alta qualidade, a mecânica voltou a funcionar perfeitamente.</span></span><br />

<span style="font-family: Arial, Helvetica, sans-serif;">As cafeteiras elétricas são bastante simples na sua concepção e de fácil manutenção. Os problemas mais comuns são a queima do fusível térmico, a queima da resistência e ainda a falha no sensor termostato.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">Na cafeteira a seguir mostro a substituição da resistência que foi o que queimou.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">Para abrir a cafeteira deve-se remover os pés de borracha pois abaixo sempre há algum parafuso. Removendo todos os parafusos da tampa inferior é possível acessar o conjunto responsável pelo aquecimento.</span><br />

<span style="font-family: Arial, Helvetica, sans-serif;">O primeiro passo foi medir a resistência, o fusível térmico que fica no lado da resistência e o termostato que está no centro da foto anterior. Com a ajuda de um multímetro pude apurar que a falha era realmente a resistência que possui o formato de uma ferradura. </span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">Para remover o conjunto basta soltar os dois parafusos da chapa de fixação.</span><br />

<span style="font-family: Arial, Helvetica, sans-serif;">Adquiri o kit da resistência no mercado livre com o vendedor <a href="http://www.mercadolivre.com.br/jm/profile?id=129961875&oper=B" target="_blank">Humberto Bordon</a> que me enviou prontamente o kit a um preço muito bom.</span></div>

<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Arial, Helvetica, sans-serif;">Durante a montagem identifiquei que a resistência anterior tocava em poucos pontos a bandeja da jarra podendo ser este o motivo da queima. Para que o problema não se repita, lixei a resistência nova com uma lixa esticada em uma superfície plana garantindo assim um melhor contato entre as peças. Além de lixar utilizei na montagem pasta térmica que também auxilia na condução do calor.</span></div>

<span style="font-family: Arial, Helvetica, sans-serif;">Após montar é sempre bom passar algumas vezes apenas água para fazer uma limpeza dos componentes internos que ficam em contato com a água.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">A forma de fazer manutenção neste tipo de cafeteira é parecida com todas do mesmo tipo e marcas. Aplica-se para as cafeteiras CP15, CP30, Mallory, Walita, Mondial, Electrolux e por diante...</span><br />

<span style="font-family: Arial, Helvetica, sans-serif;">Equipamento: Máquina de Lavar Consul Maré Super 10Kg</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">Problemas: Forte barulho de motor ao ligar a bomba para esvaziar a máquina e também o cesto de roupas parece não girar com força durante a lavagem.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">As máquinas de lavar Consul, principalmente as mais simples, são muito boas na durabilidade e na hora da manutenção com peças baratas e de fácil substituição. A máquina à seguir estava com um ronco muito alto proveniente da bomba d'água que ao entrar em ação para esvaziar a máquina produzia um ruído alto e incomodo. Outro ponto era o fato do cesto e o agitador de roupas às vezes não ter força para girar durante o ciclo de lavagem no mais a máquina estava funcionando normalmente mesmo após cinco anos de uso sem nenhum tipo de manutenção.</span><br />

<span style="font-family: Arial, Helvetica, sans-serif;">Trocado o motor, é hora de colocá-lo na máquina montando os dois parafusos do motor na carcaça da bomba e depois os três que prendem o conjunto no grande cesto. A fiação não tem polaridade definida podendo ser conectada em qualquer ordem.</span></div>

<span style="font-family: Arial, Helvetica, sans-serif;">Após a troca da bomba o primeiro passo para verificar a falta de força durante a lavagem era verificar a correia. A correia da máquina fica atrás de uma proteção de plástico conforme mostra a imagem e as indicações mostram os parafusos para removê-la:</span></div>

<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span></div>
<div style="text-align: left;">
<span style="font-family: Arial, Helvetica, sans-serif;">Removida a proteção é possível observar que a correia está bastante frouxa podendo ser este o problema, para ajustá-la apenas afrouxa-se os dois parafusos que seguram o motor principal da máquina, cuidando para não afrouxar demais e dificultar a regulagem.</span></div>

<span style="font-family: Arial, Helvetica, sans-serif;">Com os parafusos frouxos afasta-se o motor até a correia ficar tensionada, cuidando para não tensionar demais o que provocará danos aos rolamentos, polias, motor e a própria correia. A tensão correta é o ponto onde a correia fica reta sem fazer força para afastar o motor.</span></div>

<span style="font-family: Arial, Helvetica, sans-serif;">Equipamento: Aspirador de Pó Britânia ASP 1650 Turbo</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">Problema: Ao conectar o aspirador na tomada este fica sempre com o motor ligado mesmo pressionando o botão liga/desliga.</span><br />

<span style="font-family: Arial, Helvetica, sans-serif;">Para desmontar este aspirador é bastante simples, basta remover os seis parafusos que o fecham e separar as duas grandes carcaças. </span><br />

<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">Para este caso optei em reparar o interruptor que estava com seus contatos colados, separei eles e fiz um polimento com lixa 1200. </span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">A chave de liga/desliga é de fácil desmonte mas se preferir procure uma nova em alguma assistência técnica.</span><br />

<span style="font-family: Arial, Helvetica, sans-serif;">Equipamento: Chave canivete VW original</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">Problema: Após um tempo de uso a mola interna da chave não mantinha a chave aberta e travada</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">O uso de chaves canivete está bem comum hoje em dia ao mesmo tempo os problemas com a mola que a mantém aberta também.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">A seguir mostrarei algumas imagens de como abrir a parte da lâmina da chave e no youtube é possível achar como abrir para trocar a bateria do alarme e etc.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">O primeiro passo é separar a parte dos botões do alarme com a eletrônica da parte mecânica que tem a lâmina:</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>

<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">Após abrir a chave teremos as duas partes: a eletrônica e a lâmina.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>

<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Arial, Helvetica, sans-serif;">Para abrir a parte da lâmina é necessário remover o símbolo que solta quando o contornamos com um estilete. Ficará ainda a chapa de metal que deverá ser dobrada para dar acesso ao parafuso.</span></div>

<span style="font-family: Arial, Helvetica, sans-serif;">É importante cuidar para não perder o transponder responsável pelo CodeKey da chave, sem ele o carro não liga.</span></div>

<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Arial, Helvetica, sans-serif;">Feito isto o próximo passo é montar a chave criando pressão na mola e também entendendo o que aconteceu, pois não é normal a mola se soltar exceto se algo quebrar dentro da chave. Neste caso a quebra foi pequena e permitiu que apenas remontando esta voltasse a funcionar.</span></div>

<span style="font-family: Arial, Helvetica, sans-serif;">Para fazer a montagem deve-se posicionar a mola da peça 1 no pequeno eixo que existe na peça 2, colocar sobre a peça 1 a peça 3 (lâmina) e girar uma ou duas voltas para criar a pressão desejada na ação "canivete". Lembre-se de manter o conjunto pressionado contra a peça 2. Por fim tampe tudo com a peça 4. Durante a montagem procure entender o movimento da peça para posicioná-la corretamente.</span></div>

<span style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18.479999542236328px;">Equipamento: Trava elétrica original do Gol G5 / Fox / Voyage / Saveiro</span><br />
<span style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18.479999542236328px;">Problema: A trava não funciona.</span><br />
<span style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18.479999542236328px;"><br /></span>
<span style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18.479999542236328px;">Um problema muito comum nas travas elétricas é a queima do motor que faz o pino subir e descer. Não é uma tarefa simples arrumar, requer uma certa habilidade para desmontar a porta e a própria fechadura e é isso que mostrarei nas imagens à seguir.</span><br />
<span style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18.479999542236328px;"><br /></span>
<span style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18.479999542236328px;">Outro fato é que dificilmente conseguimos o modelo exato da fechadura para substituir no carro, neste caso utilizei o motor de outra fechadura que era de uma porta traseira de um Fox sendo que no Gol o motor queimado era o da porta do motorista, sem problemas, o motor é o mesmo. O motor também pode ser comprado no mercado livre.</span><br />
<span style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18.479999542236328px;"><br /></span>
<span style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18.479999542236328px;">O primeiro passo é desmontar a forração da porta para isso remova os parafusos indicados:</span><br />

<span style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18.479999542236328px;">Após remover os parafusos é necessário forçar a forração para fora, começando pela parte de baixo e das laterais, depois é só desencaixar da calha que faz o acabamento com o vidro e o pino da trava.</span><br />
<span style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18.479999542236328px;"><br /></span>
<span style="color: #222222; font-family: Arial, Helvetica, sans-serif;"><span style="background-color: white; line-height: 18.479999542236328px;">Removido a forração desconecte os cabos, o cabo de abertura da porta e remova as fitas que dão acabamento, lembre-se de <u><b>não estragar o plástico</b></u> pois é este que evita que entre água no carro.</span></span><br />

<span style="font-family: Arial, Helvetica, sans-serif;">Feita a parte interna vamos para os parafusos da fechadura, nestes é necessário atenção quanto ao parafuso que segura o tambor da chave junto a maçaneta (seta amarela na imagem). Este deve ser desparafusado até soltar o tambor da chave, para isso mantenha uma das mãos puxando o tambor para fora. Não se deve remover este parafuso pois ele segura uma chapa responsável por travar o tambor e quando isto solta é muito ruim para colocá-lo novamente.</span><br />

<span style="font-family: Arial, Helvetica, sans-serif;">Bom, a troca do motor não tem segredo, basta <u><b>marcar a posição dos fios</b></u> antes de desconectar, pois se der errado, somente depois de tudo montado é que saberás que esta errado!</span></div>

<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Arial, Helvetica, sans-serif;">Evite utilizar um motor que não tenha o eixo alongado, pois se o fizer a peça de latão que faz girar a engrenagem vai desgastá-la em pouco tempo.</span></div>

Devolvi ele ao dono. No dia seguinte ele retornou falando que tinha o mesmo problema então desmontei ele novamente e medi os mosfets e estava tudo ok, liguei ele e estava funcionando. Resolvi simular pequenos impactos para detectar alguma possível solda fria, constatei que na solda do conector de entrada de energia de 12V estava com a bendita solta fria refiz a solda com um estanhador mega power de 100W e Show de bola.</span><br />

<span style="font-family: Arial, Helvetica, sans-serif;">Equipamento: Ducha Eletrônica Turbo</span><span style="font-family: Arial, Helvetica, sans-serif;">Modelo: </span><span style="font-family: Arial, Helvetica, sans-serif;">Ducha Thermosystem Turbo 7700W - 220V</span><span style="font-family: Arial, Helvetica, sans-serif;">Fabricante: Thermosystem</span><span style="font-family: Arial, Helvetica, sans-serif;">Problema: Ao ligar a água não esquenta e a resistência é nova</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><span style="font-family: Arial, Helvetica, sans-serif;">Um problema muito comum na ducha Thermosystem é depois de algum tempo não esquentar mais a água, mesmo estando com uma resistência nova e isso se deve por algum problema na eletrônica do chuveiro/ducha.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><span style="font-family: Arial, Helvetica, sans-serif;">O princípio de funcionamento desse tipo de ducha é o uso de um circuito do tipo <a href="http://www.te1.com.br/2008/12/dimmer-com-triac-tic-226/">dimmer</a>, muito comum em sistemas de controle de intensidade de iluminação para lâmpadas incandescentes. </span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif; line-height: 1.4;">O que mais dá problema nessas duchas é o potenciômetro que é responsável pelo tempo de carga do capacitor que fará o disparo do triac.</span><br />

<span style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; font-size: 13px; line-height: 18px;">Pedi então que trouxesse a máquina até a minha casa para iniciar o conserto. Chegando a máquina logo fomos direto na placa de acionamento:</span><br />

<span style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; font-size: 13px; line-height: 18px;">Comecei olhando os defeitos mais comuns citados nos fóruns, olhando o sistema de travamento da porta visto que o resistor que controla o Triac do solenoide estava torrado, de fato o Triac estava aberto, juntamente com o conjunto de diodos retificadores em curto pois a solenoide da trava deve receber pulsos em corrente corrente contínua para travar e destravar a porta.</span></div>

<span style="color: #222222;"><span style="font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Trocado os componentes (Triac <a href="http://www.onsemi.com/pub_link/Collateral/BTA12-600BW3-D.PDF">BTA12</a> e diodos 1N4007) sem ainda remover muito da resina que protege a placa fui ligar e para surpresa nada funciona e ainda queimou mais alguns componentes... Verifiquei também que a assistência tinha removido o suporte do fusível ligando direto... Passei então a utilizar um sistema de lâmpadas em série com a ligação da máquina, sendo três lâmpadas de 100W (estas em paralelo) que se acendessem indicariam um consumo de corrente acima do esperado (curto).</span></span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="color: #222222;"><span style="font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Passei então a buscar mais informações sobre o sistema de travamento da porta que depois de abrir-lo verifiquei que há dois sensores em série, um magnético que indica que a porta está fechada e outro do tipo micro-chave para indicar se o sistema de trava está acionado ou não. Ao verificar o solenoide este tinha derretido o plástico internamente além de estar com o enrolamento totalmente em curto provavelmente por ter ficado ligado direto quando a máquina deu problema ocasionando a queima de todo o circuito que o aciona:</span></span></div>

<span style="color: #222222; font-family: Arial, Helvetica, sans-serif;">Continuando a investigação sobre o problema resolvi remover a carcaça de plástico que guarda a placa, tive de cerrar em 4 fatias cuidando para a serra não tocar na placa. Após remover as partes de plástico finalmente consegui ver a placa por baixo e de cara a trilha que alimentava o circuito de travamento tinha sumido.</span><br />

<span style="color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Tentando ligar a máquina mais uma vez, agora com o solenoide desconectado da placa e o sensor do solenoide ligado direto a máquina deu o primeiro sinal de vida acionando o display e logo em seguida informando o erro U5 indicando que havia problema com o solenoide do travamento, até aí tudo certo, entendi que se a máquina está sem programa de lavagem os sensores da porta devem estar aberto visto que estão em série e qualquer um que estiver aberto colocará a lógica da ligação na condição de porta aberta. Contornei esta situação deixando então a porta aberta quando a máquina está sem programa e ao iniciar um programa fecho a porta rapidamente pois nesse momento os dois sensores terão de estar fechado (um ficou sempre fechado pois liguei direto).</span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Então coloquei a máquina para rodar algum programa: selecionei uma centrifugação para testar o motor e iniciei o processo. Escutei alguns relês acionando, a bomba d'água mas o motor nem deu sinal de funcionar... e em seguida apareceu no display o erro EH1.</span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Pesquisando sobre o erro EH1 encontrei muitos comentários dizendo que o problema era o relé que fica próximo ao dissipador. Ao rever o rele liguei ele numa fonte de 12V e verifique que um de seus contatos NF estava colado quando então resolvi abrir:</span></div>

<span style="color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Ao abrir pensei, pronto está aí o problema, fiz rapidamente uma montagem de teste com dois relés convencionais reversíveis para testar.</span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Ligando novamente a máquina nada do motor funcionar... </span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Fiquei encucado e pensando a respeito e decidi verificar todos os relês injetando 12V nas suas bobinas e medindo continuidade nos seus contatos cuidando sempre da polaridade para não danificar os diodos de roda livre. Verificados todos os demais relês que estavam bons a placa parou de funcionar provavelmente devo ter queimado alguma porta do driver de corrente que os aciona, isto é feito pelo par de CI's <span id="goog_420383812"></span><a href="http://www.alldatasheet.com/datasheet-pdf/pdf/470261/TOSHIBA/ULN2003APG.html">ULN2003APG</a>. A placa até ligava mas ao soltar o botão de POWER (LIGAR) e máquina desligava pois o relê que realimenta não ficava acionado. Verifiquei qual era o relê que fazia a realimentação e liguei direto, a placa voltou a funcionar, substituindo os dois CI's coloquei a máquina de volta ao ponto de partida...</span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Agora o desafio era verificar o funcionamento do motor. Resolvi então remover toda a resina/silicone da placa e ao chegar perto da ponte retificadora havia uma trilha rompida, refiz a solda e fui verificar o triac que pra variar estava com o gate em curto com Mt1 e Mt2.</span></div>

<span style="color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Olhando o motor, resolvi ligá-lo numa fonte de 12V, entendi pelo esquema impresso no motor que os fios das extremidades do conector (1 e 10) estão ligados ao estator com <i>center tap</i> no pino 5, os fios 8 e 9 nas escovas, os fios 6 e 7 no relé térmico e 3 e 4 no sensor de rotação. Ao ligar direto, sem passar pelo relé térmico o motor deu sinal de funcionamento:</span></div>

<span style="color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Verifiquei então que o fusível térmico estava aberto, acredito que abriu não por temperatura mas sim devido ao curto causado por mal funcionamento no relê de polaridade que mostrei anteriormente.</span></div>

<span style="color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Apesar do vídeo ter ficado deitado, pode-se ver a máquina funcionando.</span><br />
<br />
<span style="color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Mesmo depois de colocar a máquina pra rodar, precisava trocar o relê que substituí por um </span><a href="http://www.findernet.com/pt-BR/products/sku/415290120010" style="font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Finder 4152.9.012.0010</a><span style="color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;"> que suporta em seus contatos 8A contra os 5A do relê que derreteu.</span><br />
<div class="" style="clear: both; text-align: left;">
<span style="color: #222222; font-family: Arial, Helvetica, sans-serif;"><span style="line-height: 18px;">No meio tempo dos testes, testei individualmente todos os componentes da máquina que estavam bons exceto o secador (Bumper) que ao ligar girava lentamente e depois chagava a parar. Ao desmontar foi possível notar muita agressão ao material do rolamento/mancal causado pelos produtos de limpeza, e na minha opinião quem constrói máquinas desse tipo sabe muito bem quão agressivos são os produtos de limpeza, então que utilizem material de qualidade pô!!! O que me deixou mais enraivecido foi não conseguir remover a hélice para lubrificar o motor, tive de então apenas amenizar o problema usando WD-40. Solução bem <i>meia boca.</i></span></span></div>

<span style="color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Para montar a caixa plástica que protegia a placa tive de fazer com silicone de cura neutra pois o silicone convencional agride o material dos componentes. Testada a caixa plástica contra entrada de água que por ventura venha a cair, dei como encerrado o conserto... E claro, um capricho nunca é demais, passei uma massa de polir no cromado e depois uma cera na máquina toda:</span><br />

Ao abrir a TV para avaliar o que estava acontecendo nem foi necessário ir muito a fundo na investigação: ao ligar via-se a fuga de tensão sob o flyback que já havia sido substituído por um de baixa qualidade e pela aparência da peça parecia ter sido trocado recentemente.</span></span><br />

<span style="background-color: white; color: #222222; line-height: 18px;"><span style="font-family: Arial, Helvetica, sans-serif;">Bem, dessa vez foi o lava-jato que deu problema. Este karcher é muito bom mas tem um problema com a válvula do sistema de parada total, aquele recurso que quando se solta o gatilho do esguicho o compressor para totalmente parecendo que está desligado.</span></span><br />
<span style="background-color: white; color: #222222; line-height: 18px;"><span style="font-family: Arial, Helvetica, sans-serif;">Esta válvula é chamada de by-pass e é feita de plástico:</span></span><br />

<span style="font-family: Arial, Helvetica, sans-serif;">Após três anos de bons serviços prestados aqui em casa as travas da válvula quebraram vazando água pra todo lado.</span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Arial, Helvetica, sans-serif;">Para desmontar o lava-jato desparafusa-se o fundo do aparelho, são seis parafusos e depois já se pode acessar o interruptor que está sobre a válvula. Este é preso por uma trava que parece uma ferradura:</span></div>

<span style="font-family: Arial, Helvetica, sans-serif;">Um detalhe importante de se observar é que dentro de onde a válvula atua (sede) existe uma pequena mola que deve ser mantida no local e ao montar a válvula nova cuidar para que a mola engate corretamente na ponta do eixo.</span></div>

<span style="font-family: Arial, Helvetica, sans-serif;">Passado alguns meses após a substituição da válvula do bypass o lava jato começou a pulsar quando estava parado, notei também que a pressão já não era tão forte. Pensei que com o tempo de uso o compressor começou a perder força. Mais um tempo se passou até que o lava-jato ficou com o motor ligado direto e sem pressão... Fiz então mais alguns reparos que mostro a seguir:</span></div>

<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Arial, Helvetica, sans-serif;">Desmontei o lava-jato e fui direto verificar a válvula do bypass que desta vez estava intacta então pesquisei um pouco na internet e descobri que existe mais um reparo logo abaixo da válvula bypass. </span></div>

<span style="color: #222222; font-family: Arial, Helvetica, sans-serif;"><span style="line-height: 18px;">Há um bom tempo minha esposa vinha reclamando que a função descongelar do microondas não estava funcionando bem, ao invés de descongelar estava cozinhando os alimentos. Na época acabei não dando atenção até que um dia quando estava usando o microondas este ficou ligado direto ao fechar a porta... Era fechar a porta e ele já ligava, e ligava tudo pois qualquer alimento dentro dele cozinhava.</span></span><br />
<div>
<span style="color: #222222; font-family: Arial, Helvetica, sans-serif;"><span style="line-height: 18px;">Depois do problema se agravar resolvi abrir o microondas para manutenção.</span></span></div>

<span style="font-family: Arial, Helvetica, sans-serif;">A primeira impressão que tive era de que havia alguma das micro chaves da porta com problema, então comecei medindo todas as três, o contato NA (normalmente aberto) e o NF (normalmente fechado). Os interruptores estavam normais, abri e fechei a porta várias vezes e tudo normal e então logo fui para os relés que estão na placa de controle do micro. Ao desconectar os cabos e medir o primeiro, já estava com o contato fechado direto.</span></div>

<span style="font-family: Arial, Helvetica, sans-serif;">Dos três relés dois estavam conduzindo direto ou seja, com o contato colado devido as centelhas que se formam ao desligar o relé.</span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Arial, Helvetica, sans-serif;">Por sorte tinha uma placa dessas na sucata que "herdei" da minha sogra pois o micro dela teve o mesmo problema mas na época ela mandou para a assistência que trocou a placa toda quando o problema era também somente o relé.</span></div>

<span style="font-family: Arial, Helvetica, sans-serif;">Fazendo um arranjo com o relé do grill das placas que tinha consegui colocar os relés menos usados para as duas funções mais críticas: ligar todo o microondas e o outro para ligar somente o gerador de microondas e um dos relés que após testar com uma fonte de 12V voltou a funcionar coloquei na função do gril.</span><br />

<span style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">Modelo: Linha ADSL</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">Olá</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">Este projeto é um protetor de surto para proteger os modens ADSL contra eventuais descargas atmosféricas comuns principalmente no verão. O projeto é bastante simples e tem se mostrado eficiente em vários amigos que temos que antes enfrentavam problemas de queimas constantes dos seus modems. O equipamento consiste de poucos componentes: um varistor de 110V, dois fusíveis de 80mA, dois porta fusíveis e uma pequena caixa para acomodar as ligações.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEivGZRxsl2AZCoY9rb0SAjqG_5XW0UTv3gz11wrZFyAQmaPVlFMF83vvmiNBySizcP3oqo5LpTEQC_J8-fKqCk1VaOD3TXCCybdbtgS6JOUMH-gashx5k4PMNzdktNDSSYbT-7vit56Cw/s1600/IMG_0778.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Arial, Helvetica, sans-serif;"><img border="0" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEivGZRxsl2AZCoY9rb0SAjqG_5XW0UTv3gz11wrZFyAQmaPVlFMF83vvmiNBySizcP3oqo5LpTEQC_J8-fKqCk1VaOD3TXCCybdbtgS6JOUMH-gashx5k4PMNzdktNDSSYbT-7vit56Cw/s400/IMG_0778.JPG" width="400" /></span></a></div>
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; line-height: 18px;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;"><span style="background-color: white; color: #222222; line-height: 18px;">O funcionamento é simples: como as linhas telefônicas chegam até 90Vac quando o telefone está tocando, colocamos um varistor para limitar a tensão da linha a não passar de 110V, os varistores atuarão como resistências resistência para a diferença de tensão aumentando a corrente na linha até ultrapassar os 80mA suportados pelos fusíveis fazendo com que se rompam.</span></span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<br />

Mas já ajuda, tivemos casos práticos da abertura dos fusíveis em diversas situações sem a queima do modem e que provavelmente teriam tido problemas.</span><br />

<span style="background-color: white; color: #222222; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px; line-height: 18px;">Esta sanduicheira parou de aquecer depois de uns dois anos de uso, a minha suspeita já de cara era o termostado e não deu outra... o problema foi achar um termostato que pela descrição do componente era de 180°. Acabei encontrando um de 125° mas que no final ficou muito bom.</span><br />

<span style="background-color: white; color: #222222; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px; line-height: 18px;">O sensor está localizado na parte de cima da sanduicheira, sendo necessário abrir pelo lado de dentro, desparafusando o acabamento na parte da alça e depois os quatro parafusos da chapa. O modelo do sensor que encontrei possuía um suporte de fixação um pouco diferente sendo necessário colocar um pequeno calço de alumínio para que a fixação acontecesse com pressão e transferisse o calor da chapa para o sensor.</span><br />

Recebi este aparelho dvd com a seguinte descrição, Não lê cd e nem dvd e não sai som.</div>
<div class="separator" style="clear: both;">
Primeiro passo foi verificar se a descrição do problema era verídica, verifiquei e realmente era. Próximo passo foi verificar as tenções de alimentação, tudo OK. Então verifiquei os sinais digitais nas entradas dos Chips correspondentes tudo OK. Então comprei o chip amplificador de Audio <a href="http://www.st.com/web/en/resource/technical/document/datasheet/CD00179160.pdf" target="_blank">TDA7388</a> troquei e show de bola já tinha som na saída do aparelho.</div>

Continuei medindo e cheguei na polarização do relé que acionava as resistências, constatei que a polarização estava muito boffant, fazendo que a tenção chegue a 2V quando as acionado as 3 resistências. Refiz os cálculos e alterei a resistencia de 4k7 para 10K.

</div><div class="separator" style="clear: both; text-align: left;">Depois de ler várias opiniões em blogs e afins, resolvi começar a análise das tensões do flyback, que por sinal estavam todas em ordem. Depois disso dei uma medina na fonte, pois muito se comenta que para este modelo a regulação tem de ser precisa e de fato estava tudo certo.</div><div class="separator" style="clear: both; text-align: left;"><br />

</div><div class="separator" style="clear: both; text-align: left;">Continuei medindo as tensões até que resolvi seguir a linha de 180V que sai do flyback e segue para a placa que fica atrás do tubo e constatei que não havia tensão alguma na linha de 180V logo após passar por aguns componentes próximos ao flyback. Fui então medir os componentes que fazem parte dessa linha e bingo!!!</div><div class="separator" style="clear: both; text-align: center;"><br />

</div><div class="separator" style="clear: both; text-align: left;">Um resistor de 4,7 ohms estava aberto... Mas ainda havia uma pergunta, o que causou a abertura desse resistor? Fui para o capacitor que está em paralelo com o diodo e ao removê-lo da placa para uma medição o dito estava apresentando uma resistência de 70 ohms. Substituídos os componentes liguei o televisor e a imagem apareceu normalmente. Mas ao ligar um barulho saída do conector de alta tensão do flyback, era fuga de tensão no conector com o tubo.</div><div class="separator" style="clear: both; text-align: center;"><br />

</div><div class="separator" style="clear: both; text-align: left;">Descarregado novamente o tubo, removi o conector e fiz uma limpeza em volta, inclusive na borracha.

Equipamento: No-break <br />
Modelo: Stylus 2600<br />
Fabricante: ADFTRONIK<br />
<br />
Problema: Um belo dia o dito do no-break não atuava, desligando todos os computadores na farmácia. O proprietário até substituiu a bateria, que é de carro por sinal, mas de nada adiantou, aí então ele recorreu ao consertador para dar uma "olhadinha" e ver o que era.<br />
<br />

<br />
Ao abrir o no-break, uma surpresa, todos os mosfets do inversor estavam estourados:<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi5LSZ4tTFKITXU8cvarJ_ol_1NZ3ecg4HZsvLM67lPA4jwAZ2QQRaWV4RzxLRKPVSJ-egoVQKGurTMReYO8jNSYrJX45FWpF7tZkOGIYwTHZj8Khf_9_akDPxN0rbmCT4UiBBdLg8NUQ/s1600/012.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi5LSZ4tTFKITXU8cvarJ_ol_1NZ3ecg4HZsvLM67lPA4jwAZ2QQRaWV4RzxLRKPVSJ-egoVQKGurTMReYO8jNSYrJX45FWpF7tZkOGIYwTHZj8Khf_9_akDPxN0rbmCT4UiBBdLg8NUQ/s320/012.JPG" width="320" /></a></div><br />
<br />
Após analisar descobriu-se que o problema fora causado pelo circuito de controle baseado no ci <a href="http://www.ti.com/lit/ds/symlink/sg3524.pdf" target="_blank">SG3524</a> que é comumente encontrado em algumas fontes antigas de PC e conversores PWM.<br />
Este ci danificado fez com que uma de suas saídas ficasse 5V, fazendo com que os mosfets condizissem o tempo todo e não deu outra, a explosão dos componentes aconteceu. Incluindo ainda dois transistores <a href="http://www.fairchildsemi.com/ds/BC/BC337.pdf" target="_blank">BC337</a>.<br />
<br />

<br />
