How to check for IC Tristar fault?
I replaced the rear housing of the phone and it's now getting really hot when I turn it on. The voltmeter keeps changing when I'm measuring the poles where the battery goes in from 4V to 0.4V. I've also replaced the power button but unplugged that and got the same result. The phone turns on after taking ages to charge but shows the home screen while the CPU gets really hot. I'm now wondering if it's the IC issue but I don't know how to check it.
Ist dies eine gute Frage?
