TV FUNAI 2000a mk7


Recommended Posts

Tv-ul a venit cu sursa prastie:q501,d510,q504,optocuplor,D245,IC208.In acest moment sursa functioneaza corespunzator avand la iesire 115v,12v,17v si sunt prezente si cele de 9v si 5v.Problema este ca tv-ul nu porneste si nu se aprinde led-ul de standby.La pornirea din buton ridica foarte putin inalta si moare ,tensiunile din sursa ramanand la valoarea corespunzatoare.Va multumesc anticipat pentru idei!
