Hey ! So i was changing the chassis of my iphone 6 the other day and when i finished and plugged it in the charger without screwing the lcd shield it worked for a bit but then phone turned pretty hot and the screen went yellow.. I know i messed up 2 of the screws..the one just above the right upper corner of the lcd shield and the second of the top left side of the motherboard.. Now the phone is shorted and dead and everytime i put the charger in it turns burning hot..these two screw brackets do not short to ground but after removing the brackets no damage is visible. Update (10/13/2017) thanks for the answer its not the screws of the lcd shield its the upper right of the motherboard and it doesnt seem to be damaged

i know i just messed this capacitor its gonna be in place soon Update (10/17/2017) still burning hot when i plug in the charger dont think it was long screw damage after all anyone has thoughts as of what might be shorting and how to fix this? Update (10/27/2017) after i apply the freeze spray the cpu instantly heats up and all the elements above..is it possible that the cpu is shorted ?

Are you doing that you put a long screw in one of the shorter screw holes? Are one of the screw holes on the logic board near the screen connectors broken off? I’m pretty sure the phone has long screw damage and can only be repaired by someone that does microsoldering. Example of long screw damage: https://d3nevzfk7ii3be.cloudfront.net/ig

Are you testing the short where the 2 arrows are pointing? If it is shorted there, look at everything in red to find the shorted component. The pad on PMIC is surrounded with ground pads.
