A fenti gépet meglátogatta a villám. A pfc kör totál zárlat. az alkatrész beazonosításban megakadtam. Van benne egy to220dióda a pfc körben típusa fmn1056s, ezt kéne helyettesíteni. Elvileg 600v5a 25ns. Vajon a Pfc kör mennyire kényes milyen dióda kerül erre a posztra. Köszi minden ötletet.
Sziasztok!
Lenne ez a Tv .
Csak a logóig jut, majd kikapcsol, és újra indul. Semmire nem reagál, csak ha áramtalanítom. Annyit még hogy hidegen bekapcsol normálisan kb. 5-10 secre , majd elkezd logózni.
1-888-390-12 a main, a kijelző T420HVF04.3
Mi lehet?
Kösz

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.

Trafó hibás volt.Kapott egy bontott sorkit és egy BU2520-at.Nem ad képet.Menü és TXT van.Ha tekergetem a G2-t, akkor halvány kékesen elő-előtűnik a kép.
Procc hiba?
Köszi!
