Hello.
Working on an Apple iPad Pro 3rd Generation 12.9" that has a weird issue. When the display is NOT connected, the iPad will charge and power on normally. I know it's on because I can hear notification sounds and the charging notification sound.
If I connect a brand new display to the logic board, the iPad will not turn on at all. When I connect the iPad to an 18W wall charger and a USB-C ammeter, I can see that the iPad is attempting to charge, but constantly "resets" after just a moment or two.

I have a 2020 Macbook Pro A2289 and after many attempts managed to get it into DFU mode, using my older 2017 A1706 Macbook Pro (Running Ventura 13.7.8). However, when attempting 'Restore', it fails at step 4 of 4, showing the following error:

A2338 - Pristine condition.. I took out of the board and inspected it.. nothing.. as if the computer is barely used even.
Anyway, customer said they tried erasing/formatting it and it got stuck on Apple logo preventing to go further.. I asked them why they tried to erase it from the first place? They said it turned off randomly once.. then they erased it and it worked out for a few days then it shut off again..
I put the computer in DFU; I downloaded the latest Ventura IPSW and restored it.. during the "Installing.." it restarts then it shows the exclamation...09-11-2023, 08:43 AM
