Replaced the battery i n my Samsung S10e, checked that everything was working properly, which it was. Ran the battery down to 0% as instructed to calibrate the battery. Once plugged into the charger, my screen is no longer functioning. The battery has charged, and the phone will turn on, but the screen stays blank and unresponsive. Screen is physically undamaged.
Was suggested by someone to disconnect the new battery and plug in the old battery. I did this and the screen worked again. Unplugged the old battery and plugged the new battery back in and the screen is working.
There is the chance that the screen connector became disconnected during the repair process. You’re looking at the connector shown in step 23 of this guide: Samsung Galaxy S10e Screen Replacement
