Hello there might be a glass fuse inside it will be in the power supply if black in colour it's blown. but beware if you put another 1 in and it blows again then you have a dead short someware also make sure you put the same rated fuse back in good luck

20kW Generac 20RESA cannot program to test itself on a regular basis. The LED screen is bland and does not respond to the buttons.

Is the battery system charged, normally a totally dead display is indicative of a dead DC circuit, check control board fuses also. Also have an electrician check the AC control fuses normally in the transfer switch.

No display even after the system boots

You either have a dead CPU or a dead motherboard or a partially-dead power-supply -- the power-supply should supply different voltages to different computers, i.e., one voltage to spin fans, and a different voltage to power the RAM, and a different voltage to power the motherboard. So, it can be "partially" dead.

Borrow a power-supply, and try that first.
If all else fails, take the computer to a qualified technician.

Check your power cables properly and make sure it is attached. Check your power button, maybe you have pressed the wrong one.

Black display

I'm in the same position, though my screen isnt totally dead, just very distorted and intermittent...
I know I would need to replace the flex cable, is there any guides online on how to replace them, or more specifically how to disassemble the phone?
