iPhone X PP GPU short
 

ok. I have seen this twice now. That last one was a bad A11

I have a iphone X with a PP GPU short All the caps on that rail are low ohms.

Is this a signature fail?
Last time I started pulling caps one at a time until there were none left. Then pulled PMIC then the A11. The short went away with the A11.

Anyone?


Is there a highly active forum for micro solder technicians.. ?
I find some info here but it is sparse.

Using thermal imaging "I figured out a more precise method for my Flir" using a iPad as the display and using a lens distance of less than 3".

I am 100 % positive this is a A11 chip as well.
How the hell do you fix this?

To see a video of the FLIR as the board powers on visit my youtube channel.
kcmicrotronix The name of the video is "iPhone X PP GPU short"

I am officially pulling the plug on the repair and calling it a defective A11.
no reparable.

Hello,

PP_GPU is a very low value in resistance/diode mode, are you sure you're facing a short on that line?
I have an iphone X that is booting normaly, the value for this line is 4.5 ohm.
