Sziasztok!
Ez az 5800-A5N110-02 sasszis tv szétégett a sortranyó környékén. Olyan rajzot/nyák/ esetleg képet keresek, amelyen látszik ez a rész.
Köszönöm: Vasmacska

Hello to everyone, I hope someone can help me in English :D
i have a problem with this LCD TV Akai AZ 4280FHDT4 LCD 42" .
It's power supply was fault, and I got it working, but now i have another problem, there is no picture. Actually the screen is fade white-blueish, no picture no OSD, but SOUND is working fine...
I can't find service manual for this TV anywhere... And that is even more difficult because I cant see what is the main processor and the main IC on T-Con Board, because there is a glued cooler over them.
The main board is:20-MT5362--13-OX
The card that controls the LCD screen: SZTHTFTV1607
Power supply: MLT198TL
I suspect the T-CON board, because i get 12V from main board going too it, but there is no supply for main processor on TCON (probably MST6xxx IC), there should be 3.3v to supply it, but there is not... there is i thin a DC to DC convertor that should convert 12 to 3,3 but i cant read any marks from it, so i don\t know what it does exactly.
Here is what the board is, i think, it has its cooler taken off...

If anyone knows where can the service manual can be found it would be nice...
I see that many LCD tv's have similar problems, and that the LCD driver is mostly the reason...
Is there any similar manufacturer, that could help too...
Thank you in advance
Üdv!
Megint plazma. Egy Akai PDP4206EM gépben (LG származék) van az alábbi tápegység: Unicorn USP490M-42LP.
Ebben csücsül egy (sajna döglött) PIC16LC72A. Erre, vagy esetleg ennek a software-ére lenne szükségem.
Ha valaki tudna ebben segíteni, hálás lennék.
Attee.
