11ak56 posibil cdre

Recommended Posts

Salut, am acest sasiu care face urmatoarea problema:la pornire apar trei dungi subtiri (RGB) in partea de sus a ecranului pentru 5 secunde dupa care intra in st-by. Tensiunile de 15V plus si minus sunt OK.Am scos memoria si defectul persista. Dupa schema integratul cadre ar fi STV9379FA. Merge inlocuit cu ceva sau daca stie cineva ceva? Merci anticipat.
