mircea 48-50 Posted April 9, 2014 Share Posted April 9, 2014 Buna ziua,am un tv LG model 26LC41 catre nu mai porneste.Ledul de stand-by nu lumineaza.Tensiunile furnizate de sursa sunt corecte(corespund cu ce este scris pe placa)Desigur ca nu am schema electrica.Daca are cineva vreo idee sau ma poate ajuta cu ceva eu va multumesc.Am uita sa va spun ca pe placa de baza se afla un led care lumineaza avind culoarea verde.

nostrom Posted April 9, 2014 Share Posted April 9, 2014 Fa ceva masuratori si comunica ce valori au tensiunile, comunica daca executa comanda ON. Dupa aceste verificari continuam. Quote Link to comment Share on other sites More sharing options...

dan cod Posted April 9, 2014 Share Posted April 9, 2014 Daca este LP78A foarte mari sansele ce VCTul sa trebuiasca programat. Quote Link to comment Share on other sites More sharing options...
mircea 48-50 Posted April 9, 2014 Author Share Posted April 9, 2014 Da este LT78A,invertorul pare in regula iar pe on/off este o tensiune reziduala cred de 0,0042v Quote Link to comment Share on other sites More sharing options...
