Hello everyone!
I am trying to fix a PW3 (DP75SDI with S/N starting by G090KB).
It doesn't boot at all and does nothing when connected to a PC by USB.
Silly me, I thought all DP75SDI were the same and I swapped the faulty board with another working DP75SDI board, but it turns out the working board is from a PW2, and now my screen shows as half black half white with black lines. I hope this didn't break the screen :blink:
Back to the faulty PW3 board, I am trying to see if it's possible to recover it.
When connected to the serial port, I get this (I am using CuteCom on a Rpi4):
And that's it, I don't have a clue about how to proceed now. Read about some recovery/forensic images on ixtab .tk but the site seems down.
How do I continue?
