First it showed some colorful Stripes (like a gpu fault) and than had no Image at all.

Check if has USB activity.
If yes, try known good screen.
If not, possibly RAM, or CPU issue...

Check for image on external or with know good screen? If nothing externally or you get stripes externally, dead CPU RIP.

External no Image and USB mouse has no light. I noticed that

PP3V3R3V0_AON is only 1.7V​
