Hello, I have the same problem and the same components, I do not have standby light.
How do we reprogram the firmware? Can we do it with a USB key? If so, how?

If the TV is dead, then how can it update the firmware via USB? Only a programmer and a working dump will help here.

Thanks for your answer! Even if the standby LED remains off, the USB port receives 5.5v, can't it work? So I have to unsolder the chip to update it via a programmer? (I don't have the hardware for it). In any case the problem is not hardware and comes from the chip because all the voltages are correct. Thanks for your help and sorry for my approximate English.
