Completely Dead iPhone 6 repair tried lots and no joy
Hi, I do small repairs on small devices but this is for MY IPHONE, embarrassing as I can't fix it to date. It just died one day..... and I mean its DEAD,
No response at all and the USB meter shows no current draw whatsoever. I know that this is a board level repair as I have placed the board in a working housing and still no difference. i.e. good battery, dock, screen etc. everything but the board!
I have checked for shorts on power lines and have not seen any at all. The board also looks good under the scope (nothing physically damaged - why would it it just died!)
Now as I last saw the device working before I plugged it into a car charger (yes a crappy one!) I suspected a TRiSTAR problem. So I replaced this IC and no difference, still DEAD no current draw.
All posts and forums suggest for a completely dead device either a short of U2 Tristar...
I am now thinking of the Power Management and Big Power Management IC's. Has anyone else seen anything like this before and have any recommendations before I try these in desperation?
Any help very much appreciated....

1. Try holding the power and the home button at the same time for about 20 - 30 seconds.
2. Use RecoveryTool Fix Recovery
