Hello
The TV does not show any sign of life , I started the troubleshoot as this , no power Led, no reaction when pressing the power button.
I checked the Power coming out from the power supply, the 3.3V_standby is correct and steady, then I checked the 1.2V_standby produced by IC6001 which Is good as well.
So I decided to control the main IC , IC4000 , he does not output any oscillation on the Xtal, Then I am now bloacked there.
The schematic is downloadable on this website , the schema is weird because the processor is not represented with any Xtal output, but obviously it has one.
Thanks you for your hint and help.

Annyit kideritettem,hogy ez a táp önálloan, az ic által beállitott feszültségen működik. Annyit csináltam ,hogy átmértem a táp alkatrészeit mivel jonak mértem kicseréltem az ic-t de nem változott a helyzet. Azt érzékelte a táp, hogy feszültséget kap, egyet cicegett de semmi nem történt.Kérem a segitségüket
Tisztelt Kollégák!
Készenléti táp van, de a stby led nem világít a főtáprelé sem húz be. Ha átkötöm a sor elindul képeltérítés hibával.A led ekkor sem mutat életjelet.A tápok megvannak amit tudtam mérni, mert szerviz szempontból katasztrófa ez a készülék az M-board rövid csatlakozói miatt.Ha lenne ötlet, megköszönöm.
Köszi, üdv, kovácsa,
Üdv!
