Tv nu porneste, nu se aprinde led-ul de standby si am 4 ohm rezistenta pe optocuplor in primar. Optocuplorul dat jos e ok. Are cineva o schema pt tp.s506.pb818 ?

Doar pin 1 este legat la GND printr-un condensator. Am dat azi comanda de 1 OB2263 si vad cand ajunge cum se comporta

Nu are nimeni o astfel de placa defecta, cu probleme de soft sau sa aiba tensiunile pe secundar? As cumpara si una partial defecta daca nu gasesc acest integrat.

Stie cineva cum se intra in service meniu? Cu meniu 7425 nu merge.

Edit: Am gasit codul Meniu 1147
