Maintenance of Dell XSP 15-9570 notebook computer with dark screen at startup

IMG_262
Dell XSP 15-9570 laptop has a dark screen when it is turned on. Visually, the BIOS and CPU have been passive. It is wrong to measure the voltage of EDPVDD to 0V, and then measure that the 19, 20 and 21 pins of the screen are also 0 V. Dismantle it and replace it with a good one, then connect it with electricity for testing. When it is turned on, the EN voltage is 1.2, and it is turned on normally.
