Screen stopped working after battery replacement

So I just replaced the battery in my Samsung Galaxy S10. After installing the new battery and the charging coil, I turned the phone on to confirm it still worked. Everything looked good, I unlocked the phone, made sure the touchscreen worked fine, and turned it back off. Then I glued the backplate back on.

I set the phone down with books for an hour to dry like the instructions said, then when I go to turn it on , the screen never turns on. It buzzes, and I get notifications, but the screen is just completely black.

Any ideas?

Answer this question I have this problem too

Is this a good question?

Hopefully the cable going to the LCD from the board became disconnected which should be a quick fix. If that is not the case, it is possible that the OLED panel of the display was damaged which would give the symptom of the phone powering on vibrating/making sounds but not showing anything on the display.

i have similar problem, replaced the battery but while checking found out that the screen is working improperly. Flashing , touch doesn't react always and everywhere. It's been about a 2 hours science replacing. I believe that the problem could be in amount of alcohol that I put while replacing. Idk, hope it works in the morning.
