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.

Segítséget szeretnék kérni.Van egy Sony Bravia KDL32R420A típusú tv.
Bekapcsol bejön a SONY logó néhány másodpercig és kikapcsol aztán újra be és szintén csak a logóig jut,ez ismétlődik míg ki nem húzom a konnektorból.Távirányítóra nem reagál.
A feszültségek rendben vannak,kondik jók a tápban,semmi hibát nem találok.Gondolom újra kellene írni a firmwart,nekem egy CH341A típusú íróm van,de azzal nem tudom újra írni mert nem 25Q flash van benne.
Ha van valakinek tapasztalata vagy tipje és megosztaná megköszönném,nekem még nincs nagy tapasztalatom.
Main típusa 1P-012CJ01-4010
