I have seen this a few times but never really fixed it.
The PP5V_MAIN_ALSCAM_F fail was dead at J8550. A burnt inductor was obvious on the LB.
Repaired the damaged traces and was able to return power to PP5V_MAIN_ALSCAM_F at J8550 but still no display.
These machines come in for damaged displays and when they replace the screens and they still don't work I end up with them. I was wondering if anyone has figured out what else gets damaged when this goes. There is a similar fault on the 820-01521 and my repairs have met a similar fate. All the rails on J8550 are present and the machine does boot just no image.
