Sziasztok
Szükségem lenne eme gépezet szervíz belépésére... Át kellene állítanom 10 bitről(LGD) 8 bitre (AOU) a kijelzőt.. Ugye valahogy meg lehet csinálni?
Előre is köszönöm....

Üdv. kaptam egy LG43M6300PLA lcd tv-t bekapcsoláskor bejön a menü meg kiirja ,hogy no signál de a fehér szin helyett kék szinü mi lehet a baj köszönöm a segitséget
Szevasztok!
Segítséget kérek egy fent említett LCD táp javításához.
A tápegység működik, de a PFC áramkör nem, a puffer 320V.
A táp panel száma: EAY4050500; LG37-08H.
A PFC IC típusát nagy nehezen sikerült leolvasni SG6961ZS. Ennek az IC-nek az adatlapja megvan, de az azon levő applikáció, nagyon nem hasonlít a modulon levő kapcsoláshoz.
Ha volna ilyen rajza valakinek, bizonyára sokat segítene.
kösz és üdv
A hibát a PFC (SG6961ZS) IC hideg-forrasztása okozta, a puffer feszültség 389V lett.
Sziasztok!
Ennek a masinának a szervízmódba való belépésére lenne szükségem.
Köszi : Laci
