Sony KDL-37EX402 the TV in dead, no LED, motherboard problem.
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.
Sony KV-29FX30K Tápja nem indul. (Megoldva)
Sziasztok. A fent említett tv táphibával került hozzám. A sorvégtranyót kiszedtem és egy izzót kötöttem be. A táp így sem indul. Késszenlét van. Ráindításkor meghúz a relé majd egyből el is enged és 11-et pislog a piros led. A kondenzátorok vizsgáálatával kezdem. Mit jelent a 11 villanás? Hol lehet a hiba? A segítséget előre is köszönöm.
