Tv Toshiba 1435XS cu probleme

Recommended Posts

Am problema cu acest tv pe BV, am schimbat integratul, cu toate ca nu era stricat (cred).Initial am avut TA8403K, insa din lipsa acestuia am pus LA7830, nou.

Pe pinul de alimentare am 25V, pe iesire am 12,74V, condensatorii i-am schimbat, bobina este buna si nu cred ca ar avea spira in scurt, nu prezinta urma de oxizi, ~11 ohmi.

 

Am schimbat si jungla crezand ca este din ea, insa tv face la fel....rog un ajutor in lipsa osciloscopului.

stima
