Problema TV

Recommended Posts

Acum o luna nu mai mergea tv-ul, I-am gasit un tranzistor ars A7xx si nu mai stiu cum, l-am inlocuit cu un A733 si a mers pana azi cand sa ars si A733. Nu mai gasesc prin piesele mele niciun tranzistor gen Axxx. Cu ce pot inlocui acest tranzistor sa mearga tv-ul?Merge ceva gen BD140?
