So I have this Asus TUF laptop ( BOARD ID : DA0BKXMB8D0 ) which has no backlight. tested this with multiple screens and each has different result.
Original Screen ( FULL HD ) :
Has Data
No Backlight
0V on EDP connector Pin 39,40
Backlight Enable has 3.3V
TEST Screen 1 (ONLY HD)
No data
No Backlight
8V on EDP connector Pin 39,40
TEST Screen 2 (ONLY HD)
No data
No Backlight
5V on EDP connector Pin 39,40
LDVS CONNECTED TO MB BUT NOT TO LED SCREEN
19V on EDP connector Pin 39,40 and also on the display cable ( So probably not a cable issue I think )
Attaching schematic .Would love to know what exactly is causing the drop in 19V Vin that is connected to the LDVS .
