Szia mindenkinek, aki nem tud aludni.
Keresném a legolcsóbb beszerzési forrást, ha valaki már utánna járt az alábi YSUS - bordnak: EBR39206201 (42X4A)
Sziasztok!
Áram alá helyezve indul, feléled a kijelző rajta "no signal" felirattal, viszont ha a távval próbálok valamit buherálni hamarosan lefagy az egész és csak enyhe fény van a kijelzőn. Tápfeszek rendben, kivéve az Y meghajtókon ingadozik a feszely 40...58V közt. Próbáltam egyenként kivenni a 2db Y panelt,hátha valamelyik döglődik, de ugyanaz a helyzet.
Valaki ismeri ennek a lelkivilágát?
Van egy LG cf21e20x tv beadta az unalmast. Annyira sikerült javítanom, hogy elindul, de kikapcsol, mintha időzítve lenne. Először kb. 30p, utána 20, 10,5.
minnél tovább van bekepcsolva, annál hamarabb kapcsol ki.
Táphiba?
Tisztelt Kollégák!
A fenti tv, ha kikapcsolom, pár másodperc múlva visszakapcsol, ha a key-t lehúzom, akkor is. Tápok mérve jók. Találkozott-e valaki hasonló hibával? Lehetőleg alaplap-csere nélkül szeretném megoldani.
Az ötleteket előre is köszönöm.
Horváth József
