1 Motherboard overheats when powered up
So I’m still a beginner in microsoldering but I like to experiment with boards. This is how I learn.
I have a board here that was working perfectly fine but when a friend of mine want to put the logic board in a new backcase and he powered the phone one, it showed the temperature warning and I felt that the left/long side of the logic board got very warm.
i was inspecting under my microscope because I thought this might of been the power button connector which might be bended or something but i think it might be screw damage, can anybody tell me for sure? I will post pictures I appreciate your help and support
the screwholes warm up the most and immediately cool down when i disconnect the battery
Is this a good question?

what does it pull on dc or do you have a dc power supple you can use
?
which screw whole is that on the board

Hey Kyle thanks for your response, I'm afraid that I do not have a DC power supply, i have the battery which I fully charged and also a voltage meter
The first screwhole is the one the left with the diagonal cap, the second picture is the screwhole which is grey on the pads viewer (ground) and the last one is the screwhole on the upper right corner

i do not feel it is screw hole damage i have seen worse and it not be screw hole damage i fill you have a short put your meter in continuity mode stick red on a ground pin and black on the screw hole if you get beeping its shorted to ground

@lbsocal12 thank u so much i have short on the first screwhole, how do i fix this, just remove screwhole and make jumper with cap?
by Andi Shabanaj
remove the two caps on line do not jump cap test see if it fixes the problem there are only two caps and a resistor on that line one cap is no stuff so the other should be right next to it
