Kérdezném a kollégákat hogy volt e hasonló problémája valamelyikőtöknek,ez egy 3csöves projektor, ha a kontrasztot leveszem akkor nem tilt le,kb.másodpercenként eltűnik visszajön a kép.
A tápot terheltem egy 220-as izzóval a 135v kimenetnél pluszba akkor nem történt változás ami arra utal
hogy nem a táp tiltogat le valószínű hogy a sugáráram korlátozás.Szerintetek?
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!
Kihajítás elől mentettem.
Bekapcsolás után a kijelzőn megjelenik az üdvözlő Sony felirat, egy belépő zene kíséretében :D , majd leáll, bal alsó sarkoban kiírva, hogy takarékos üzemmód.
Frissíteni kéne a gépet, vagy mit mondtok? Flash hiba?
Köszi!
Üdv:
Pityesz
keresek M-boardot vagy SAA5665HL/M1/0724 microcontrollert.
