Problema LCD LG 42LD450


Recommended Posts

In timp ce functiona a disparut imaginea, ecranul s-a facut negru, a ramas doar sunetul. L-am inchis, l-am deschis din nou si am observat urmatoarele: ecranul ramane negru, are sunet timp de 10 secunde de la pornire dupa care led-ul de stand-by incepe sa clipeasca intermitent. In cele 10 secunde de sunet fara imagine m-am uitat la spatele tv-ului si nu se mai vede lumina de la lampi. A mai intalnit cineva acest defect? Multumesc frumos.
