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.

I get to the part with the voltmeter but I don't get a constant reading and it rapidly changes.


@refectio you're pretty amazing at this stuff. What can you suggest?


There's some good stuff in the answer you linked. Plus, the link provided by Wires Computing is very good also. However charging problems can also be related to TIGRIS or even the PMIC.

The breakout board style tristar testers are total garbage--they have too much noise and the problem of integral damage to fine traces within a chip does not produce a diode mode detectable change in resistance at the scale we can detect signal to noise.

However, a German guy developed a digital tristar tester that uses a functional test of the tristar lines and that has proven to be an indispensable tool, at least in our shop. It is too expensive to make sense for DIY, but most independent repair shops will have one these days and it doesn't hurt to ask to borrow it for a minute.

This is the "good" tristar tester. https://ipadrehab.ecwid.com/#!/Digital-T...
