you've been in it for so long, you shouldn't have any problems with the basic methods of mictoelectronics diagnostics. Take a multimeter and check the voltage and resistance values of the backlight power channels. Don't forget about continuity of logical lines. Finally (if not electronics), it may turn out that the LEDs on the screen have turned off (maybe due to previous experience or simply because of a damaged connector). Change a screen assy for test.
