Hello everyone!
I have the same board 715GC925-C0B-002-004D and the latest official firmware TPN236E_236.006.107.001 - Date: 2025/12/08.
The TV doesn't start, only red LED blinks. This happens after a power surge. I chech the power supply and is OK, only the firmware got corrupted.
I try to force flash the firmware trough USB conected by holding the power button on TV then conect to mains but no avail, also holdin remote OK button but same situation.
The USB LED start blinking for about 3 second and the TV front LED white then nothing, it comes to initial state. I also try to rename the firmware file as autorun.pkg upgrade_loader autorun.pkg etc but same problem. I try multiple USB Fat 32 which I know they are goog as I work with them many times before with no problem.
Does anyone have the solution on how to successfully force update the firmware trogh USB on this motherboard?
Many thanks in advance!
