Acest tv a fost traznit.Am schimbat integratul din sursa,tranzistorul,optocuplorul,dioda6523,rezistorul 3523,tranzistorul 7540,dioda 6540.Acum tv-ul nu porneste,tensiunile date de sursa oscileaza,cea de 95 intre 50-113v,cea de 12 intre 5-9v.Cu tranzistorul final linii scos sursa scoate 123 v respectiv 8v dar cu oscilatii de circa 1-2v.Am verificat componentele din circuitul de st-by,7541,7542,6569,6570,6566 si par bune.Dati-mi va rog o idee caci eu m-am blocat.Va multumesc.
