This TV after a power failure has turned on again with a dark screen, the backlight no longer works, instead the screen image with external lighting and the audio are ok. I checked the led bars but they are fine, then I think of a firmware problem. Does anyone have the update file to upload to a USB stick or the dump for the spi? Thanks!

You need to make sure it's not a backlight problem. Recovery firmware:

Excuse me the extracted file mb140.bin do I have to insert it into the spi via programmer or copy it to the usb stick?

It's for the stick. It is installed with the OK key.

The problem was not what I thought: even if while I was testing the led bars seemed fine, one led had a false contact and was faulty. Thanks for the firmware anyway!
