Doresc o schema de la sursa EAX32268501/14 rev1.4 de la LG32LC51-ZA

Tv nu porneste la prima introducere in priza, avind  ledul rosu aprins si comanda de pornire ok. La a doua introducere in priza tv porneste fara probleme. Verificat condensatori electrolitici de pa placa sursei ok.

Multumesc. N-are acest integrat. Condensatori electrolitici cu posibile problem I-am inlocuit.

Este schema sursei LG=EAX37617801=LGLIPS42V2=LGIPS37V2 fara Q607,publicata in revista nr28 pag 106. Timpul impulsului de pornire este foarte scurt, de citeva secunde, dupa care intra in protectie si nu pot sa depistez cauza. Tensiunea ST-5V este ok. Ce sfaturi imi dati?
