Sziasztok a fenti tv-hez keresnék nand flash mentést.

Sziasztok!
Hozták a fenti tévét, hogy gond van a hangjával, néha sokat (órákat) kell várni hogy legyen, a kép mindig teljesen jó.
Először azt gondoltam kh-s, kerestem, de nem úgy tűnik, hogy ilyen jellegű a gond.
Egy chromecast-et kötöttem rá, ezzel ütemesen (1-2mp) van hang/nincs hang (ez inkább egy magas frekvenciás sípolás).
Tv adónál valóban nincs hangja (kb fél órája megy).
Ha a végfok bemenetéhez hozzáértem, akkor folyamatosan volt brumm a hangszórókban, emiatt szerintem az oké.
Próbáltam áramtalanítást / teljes resetet, nem segített.
Main: TP.MS3663T.PB708
Van valakinek ötlete/tapasztalata ilyen hibával kapcsolatban?

Hello,
I have this LCD TV which has a very white screen, the picture is visible. I could not find any fault on the CCFL Lamp inverter and was suspecting the T-Con panel of failure. The T-con panel is integrated in the control board. What i did is using "freeze it" cold spray i sprayed one of the IC's and it cured the fault. Perhaps the IC needs to be replaced. The part number is AS15-G. This component is not available for purchase in south africa and i would need to import it from china. This part is a LCD voltage buffer.

Dear all,
this TV, Hisense H60N5705 installed in a conference room, turns off automatically a few minutes after being switched on.
The problem started to occur suddenly, during a video conference. It was switched on with the remote control, continued to work for a while and then switched off again.
The room technician changed the power cable (?), the HDMI cable (??) but the problem of course remained.
I asked if it changes anything by connecting the TV to another source but, even if it is left on the OSD menu, it stays on for a few minutes and then switches off.
So they took the TV (a 60’ which is not easy to handle) to the lab and asked me to check it.
I still have to open it up, but I don't have the schematic diagrams and should proceed by trial and error, although I imagine a problem with the power supply stage.
How do you suggest I proceed, since I don't do TV but RF ?
Thank you for any help,
Best
Maximus
