Acer Nitro 5 AN515-54. displays on the external monitor and works fine, the issue is NO display on the internal screen
Good day!
I have a customer's laptop — Acer Nitro 5 AN515-54 (EH5VF - LA-H501P). It has a display on the external monitor and it's working fine, but the issue is NO display on the internal screen. I already replaced the eDP cable and checked the LCD connector pins.

- EDP_HPD – 3.3V briefly, then drops to 0V
- PCH_BKL_PWM – 2.2–5V briefly, then drops to 0V
- EC BKOFF# – 1.8V briefly, then drops to 0V
- PANEL_OD_EN – 0.3V

yx-305d bench power supply decreasing voltage problem
This power supply is 30v 5amp. Problem is when turned on after about 3 minutes voltage starting to decrease slowly. (like - 5.8 > 5.7 > 5.6 > 5.5) can't see any damaged component or dry solder joints. Checked main 2 transistors with multimeter. Reading seems ok. Tried changing potentiometers(both coarse and fine) still the same situation. Can any one help me to troubleshoot? What voltages to check? Any ideas helps to fix this. thank you.!
