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.

Sziasztok!
A fenti tv-n csak a készenléti kék led világít,a tápok felkapcsolt állapotban vannak.
De semmi életjelet nem mutat.
A memória 24C32W nem kap semmilyen tápot,nem is látszik,hogy honnét kellene kapnia.
Üdv: Wolf
Üdvözlök mindenkit!
Ehhez a tv-hez keresek mükődő mainboardot mert sajnos az ügyfelemnél villám után kilyukadt a proci.Akinek van bontott mükődő,szívesen megvenném tőlle.

Ha nincs ilyen méretben,lehet jó a 42 colos verzió is hozzá gondolom sokba nem különbözik.
Segítségeteket előre is köszönöm.
