smart tv samsung


Recommended Posts

model:UE37D5720RS,se manifesta in felul urmator,bag stecherul in priza apare imaginea si se aude sonorul pt cateva secunde dupa care se opreste si reporneste din nou.acest ciclu de oprire si pornire se repeta la nesfarsit.Am masurat tensiunile in acele cateva secunde in care functioneaza si sunt corecte iar cand se opreste scade si tensiunea de pe C-ul de 100uf/450v de la 390v la 360,iar cand reporneste tv-ul creste iar la 390.

Sa faca acest defect din cauza softului?
