Kedves kollégák!
A készülék külső tápos. A táp feszkók az alplapon mindenütt rendben megvannak. Készenlét nincs. A proci rezonátorán a feszkó feltünően kicsi:0,8V.
Valószinű,hogy flash tartalom hibás.Persze ebben bga nand flash csücsül.Nyilván csak EMMC módban lehet programozni.A gyári firmware tartalmat USB-n keresztül nem látja,már csak azért sem,mert az USB portok nem kapnak tápot sem. A main tipusa:1-980-837-11
CPU: MEDIATEK MT5832DGIJ; NAND:KLMAG1JENB B041. Én nem találtam róla semmit,se rajzot se tartalmat.Ha valakinek lenne valami ötlete vagy infója az csúcs lenne.
üdv.

Screenshots of problem here in the post.
Picture of screen with both cables to panel from TCON connected, and the other is with one side disconnected.
I have read the cables from the TCON to the display loosen up on the end to the panel. I believe as I am working on moving the cables around, the picture is improving
and getting clearer. So I think thats the problem. Someone mentioned using tape over them to hold them to the panel better. I have not taken the metal frame off to
look at them, but there is a narrow gap where I read some people stuff cardboard in there to press down on them better.
Has anyone ever seen this issue and come up with a good way to resecure the cables?

Tisztelt Kollégák!
Készenléti táp van, de a stby led nem világít a főtáprelé sem húz be. Ha átkötöm a sor elindul képeltérítés hibával.A led ekkor sem mutat életjelet.A tápok megvannak amit tudtam mérni, mert szerviz szempontból katasztrófa ez a készülék az M-board rövid csatlakozói miatt.Ha lenne ötlet, megköszönöm.
Köszi, üdv, kovácsa,
