TV NEI 2164 TXS

Recommended Posts

Buna seara,

 

TV Nei 2164 txs sasiu Beko 10.3; sursa TDA 4605, procesor SDA20563, H/V TEA 2019. Problema cu acest Televizor este ca in standby ledul pulseaza (se aud pocnituri si in difuzoare). Partea interesanta este ca se poate porni de la butoane (program+) dupa care toate tensiunile sunt bune. Am masurat in standby tensiunea de 5V ce alimenteaza procesorul si pulseaza(4.8v-5v). Am inlocuit condesatorii electrolitici (primar/secundar). Am testat sursa, pe bec este stabila, toate tensiunile sunt bune (cu exceptia 12V care este conditionata).

Aveti vreo idee? Ati mai intalnit asa ceva?

 

Multuemsc!
