Sziasztok!
LG 26V5500 TV fehér LED egyet villan de se kép se hang a tápon 24,8V mérek, mi lehet a hiba?
Előre is koszi.

Üdv Mesterek! |
Üdv mindenkinek!
Hoztak egy villámcsapott LG RE-21CC20MX tévét amiben a
táp IC + stab tönkrement. Cseréje után a tv elindult.
Hiba csak az,hogy a fényerő gyenge és alig van kontraszt.
A teletexnél tökéletes a fényerő és a kontraszt is-,jel
nélkül a kék háttér is. Ha valaki már találkozott ilyen
hibával kérem segitsen.
Előre is köszönöm Beni 1
Üdvözletem!
Ennek a készüléknek ledes háttérvilágítása van, ám ez nem működik. A ledekre menő feszültség hullámzik, néha csak 8 néha 24V. A tápegység többi feszültsége stabil, hang van, egyéb funkciók működnek. Mivel 160 V-os kondi van szűrésnek, így gondolom jóval nagyobb tápot kellene kapniuk a ledeknek. Néha kicsit meg-meg villán a háttér fénye. Sajnos rajzot nem találtam róla a tanyán.
