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 !
Sony hibákban jártas kollégák hátha tudnak segíteni. A fenti tv képe a mellékletben. Lvds, és a cof csatikat megtisztítottam, de semmi változás. VGL, VGH, GAMMA , 3,3 1,8V feszültségek renedben.
T-con csere, vagy kijelző hiba? Ilyen hibával még nem találkoztam.
Köszi !
