Okay, friends... i just won the bids on Ebay for this defect 4K TV. seller description backlight come on and the Ambilight too, but the screen remain black. no more info about the sound. photos attached from seller side..

Code:
tpv_nt315_2k19_isp.bin
tpv_nt334_2k19_data_isp.bin

I think more than likely...It has a loose muffler belt. no wait a minute...that's what the mechanic said was wrong with my ford mustang.

(Signature) One of the first and least expensive things you can do when you have an issue is take the powerboard out of the tv, flip it over and look the solder joints over with a magnifying glass if needed, add a little flux to make the solder flow well and add solder to any joints that look even a little suspect. You can practice on a scrap pcb board if needed, careful not to bridge any joints, and always let the board sit for quite a while or discharge the big caps with an appropriate resister before working on it (safety first) to try to keep from getting shocked, it doesn't take 1000 volts to KILL, a lot less can kill, so be careful, it's only a tv. THANKS FOR THE NO TIP POLICY....WELL NO TIP NO WORK.

Probably a bad component on panel driver board but hopefully it's as easy as just the firmware that you mention.
