I’ve replaced my iphone 11 pro screen, loud speaker, and battery. Everything is normal but after 2 days the screen went black but the phone vibrates/plays sounds when plugged in. The only fix to this is unplugging the battery’s flex cable then the lcd turns back on. This cyle went on three times then Ive tried another lcd but the same issue persisted. Im at a loss, what could be the problem?

If the phone still vibrates and makes sounds but the screen randomly goes black, and it only comes back after disconnecting the battery, that usually points to a board-level issue rather than the display itself, especially since you already tried another screen.
On the iPhone 11 Pro this can be caused by a failing display power line, a short around the backlight circuit, or a power management issue triggered after the repair. It can also happen if there’s slight damage near the display connector or a component was disturbed during the battery or speaker replacement.
If it turns on long enough, check Settings > Privacy & Security > Analytics & Improvements > Analytics Data and look for panic-full logs. You can upload those to an online panic log analysis tool to see if there are display power or PMIC-related crashes happening before the screen cuts out.
Since swapping the LCD didn’t fix it, this is likely a logic board fault that needs microsoldering repair rather than another parts replacement.

Most likely something to do with the proximity light sensor not functioning properly
