++@merinorus++ I’d start of with some simple voltage testing. Check on R9704 and see if you have 12VDC there. Check on F9700 and ensure it has continuity and 12VDC on it.

@merinorus that is FB9708. If you have 12V on the points you are showing but not turning on then you may have issues with eitehr Q9702 or with the backlight enable circuitry. [image|1501225

it would be good to know if the backlight has worked before or if there was any work done on the board.
