Problema tv Vestel

Recommended Posts

Am in lucru un tv Vestel sasiu 11AK03-20 care dupa memorarea posturilor memoreaza ok dar in timpul functionarii pleaca de pe post.Am verificat tensiunea de 33v volti si este fix 33v dar pe pinul de acord al selectorului la apasarea unui program memorat tensiunea este stabila cateva secunde dupa care se modifica aleator pana la 1-2volti.Rog putin ajutor.Nu am modulul cu procesorul sa probez
