IPad Pro 12.9 short on vcc_main. No schematics

Hello Azim. Unfortunately, there are no known schematics for the iPad Pro. Our fearless moderator, @oldturkey03, did answer a similar question (Anyone got back light schematics?) a while back and he had found some images with some markings which may help you a bit. You could also ask on the Facebook Intro group or GSM Forum as you will get more varied ideas and opinions as well…who knows, maybe someone out there has seen a pattern in VCC_MAIN issues on the pro. Report back if you find anything so that we can all benefit.
