la acest lcd, defectul se manifesta dupa 5-6 minute de mers, in sensul ca decupleaza releul din sursa, trece in s-by, apoi porneste dupa cateva secunde, functioneaza iar cateva secunde si ciclul se repeta...verificate lipituri reci, schimbati conzi din alimentare, face ce stie...credeti ca-i de vina memoria?...daca il fortez pe on cu 5v, oare se strica mai rau?

asa am zis si eu...am pun POWER ON la 5v printr-o rezistenta de 1k intrerupand bineinteles traseul dinspre procesor pe care venea aprox 3v cand tv-ul pornea, releul bineinteles ca a anclasat, tensiunile pe MB erau cele normale, 1,2v - 3,3v - 9v -12v, dar tv-ul nu porneste...refacand la loc legatura intrerupta, si mai nasol, tv-ul nu mai iese din s-by orice i-as face, adica din butonul on-off nu mai ia nici o comanda...ledul rosu palpaie continuu cam la 2 sec ...oare asa sta asta in s-by sau acum trebuie pornit din telecomanda pe care din pacate nu o am....
