Sony KV29FX30E tv be,keresek kifogástalan ,jól müködő belsőt FE2 sasszé.
Sziasztok!
Kaptam egy ilyen TV-t. Stand by nem világít, semmi életjelet nem ad. Külső táp jó, belső segédtáp panel is jónak tűnik. Ha lehúzom a maint róla, akkor elindul a háttér. Így egyértelműen alaplap hibának tűnik. Alaplapon zárlatot multival nem találtam. Jól gondolom, hogy engedjem el? Illetve másik működő alaplap egy próbát még megérne esetleg, de gondolom fehér holló kategória.

Helló!
A címben említett lapot keresem, ha esetleg lenne valakinek elfekvevő készleten akkor szívesen megvásárolnám :)
Előre is köszönöm a segítséget!

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.
