Hi there,
first of all I wanted to introduce myself: My name is Jan and I run a repair company in Germany. We are specialized in board repairs for Apple and Samsung devices.
I am new to the board and hope we can learn from each other with every new case being discussed here.
Today I need some help with a 15" Retina 820-3332 board.
The board came in with liquid spill, which we cleaned up. After this, we replaced the eDP connector and a whole bunch of smaller parts in that area. After that, the machine booted fine, except there was no video. Trying an external screen showed that the machine booted into the OS and runs without any problems. As soon as we disconnected the external screen, the internal video magically appeared and stayed until the machine was rebooted.
This can be done over and over again. We then repeated the ultrasonic cleaning and ran ASD which showed some errors with the GPU and the GMUX. So we reflowed U9100 and the image appeared right after starting. We tried this around 10 times and were ready to hand out to the customer but then the issue resurfaced. Another reflow of U9100 didn't help.
So this is the history:
Water damage repair (ultrasonic)
eDP replacement together with almost all little parts in that corner
Ultrasonic
GMUX reflow
GPU replacement
These are the errors from the latest ASD:
Any ideas what that can be?
Thank you so much!
