Saba sasiu TX91

Recommended Posts

Buna ziua , acest Saba M3716 sasiu TX91 a venit cu sursa defecta tranzistorul BUL310 in scurt . Am schimbat BUL310 , TEA2261 , rezistenta 5ohmi/5W de pe 300V , citeva condesatoare electrolitice de pe linga CI . Acum televizorul merge dar din zona sursei se aude un zgomot ca un sfarait si cind este semnal si fara semnal , m-am gindit ca din cauza asta s-a defectat sursa . Va rog sa ma lamuriti daca ati mai intilnit defect asemanator . Multumesc .
