Üdv. Mester urak!
Nevezett tv-re rádugták a külső tunert, szikrázott a csatlakozó, és utána már csak egészen halvány a kép. A tápegység kimeneti feszültségei megvannak. A távirányítóval a fényerőt változtatva az osd-n mozog az oszlop, de nem változik a fényerő. Hol lehet a hiba? Esteleg az EPROM tartalom megsérült?
Üdv:
Sziasztok!
Ez a készülék tegnap megadta magát, hang van a képernyő sötét de a képernyő tetejétől kb 5cm-re 3 színes csík megjelenik, piros, zöld, kék.
Szemmel látható hibát nem találtam, a 200V meg van, az R-G-B katódokon 125-130V-ot mérek.
Valaki találkozott-e már ilyen hibával?
A válaszokat előre is köszönöm.
LG 32LV5590 , fordított kép!
Valakinek van ötlete, hogy mi okozhatja?
