The screen keeps tapping by itself after I got a new screen put in

There is a temporary fix. Basically, redo the steps here Make sure you put the screws in the proper place, this is an easy mistake that’s costly. You may also want to inspect the cables for damage. Right after you put back the cables after disconnecting it should temporarily correct the issue. If it does not the part is damaged OR if the screws were misplaced then the unit is damaged. I also state this is temporary because there is a slight chance that it will return more or less due to the part/or board being the issue. Give it a try and let me know! Hope this helps
