Udv mindenkinek! Elado uj 29" LG lcd-hez smps(EAY40504401).Erdeklodni privatban.
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.
Üdv!
A készülék pár percenként kikapcsol újraindul.
Eddig arra jutottam, hogy nem táp hiba. Ha folyamatosan kényszer indításba teszem a tápot akkor a feszek megmaradnak. A készenléti fesz is stabil. Amikor kikapcsol, akkor a power on láb lemegy 0 ra majd pár sec és újra vissza3,3vra. Az inverter kapcsoló láb is hintázik ugyan igy. A vez feszek a sub micombol jönnek, de nem tudok rájönni, hogy mi kapcsolgathatja ki be. A tápja stabilnak tünik a procinak. Tasztot levettem de nem segített.
Szervusztok!
