iPhone 8 Won't Turn On, No screen, Very hot

Hello!

My iPhone 8 has stopped working after I charged it, the screen was black and the phone was very hot, I tried ‘hard reset’ and charge it after my battery was drained. However, it didn’t work at all (not getting even warm from charging). I ordered a new battery and a board to charge the battery. The old battery was dead, I couldn’t charge it even with the board. The phone still didn’t boot up with the new battery, the screen was black, the board got hot in the upper part

Here are my phone’s measurements https://ibb.co/0cmjNhf

Actual photos of the board. https://ibb.co/ThBmkdn

Thanks in advance for any help!

Edit: Found out that u3100 is getting very hot.

The board has developed a short, most likely on the PP_VDD_MAIN line. Test this line first. I have marked a test point for you.

Thanks for your fast reply. I'm not sure what 'PP_VDD_MAIN' is as I don't have any schematics of the phone.

The test point you marked shows 408

@mrfarnhigh That reading doesn’t sound right but it is not shorted. You need to rule out faulty parts first, after that you will need a set of schematics and Broadview software as well as other testing equipment like a DCPS and some squid connectors to diagnose any further.

This might either be because of the battery or overheating. Try to remove the battery or cool the wole phone for a day, and then turn on.
