Did screen repair and now it restarts every 5-10 mins

So I had done a screen repair on a iPad 10.5 inch didn’t check before to see if it was doing this but now it is and I don’t have the other screen because it was broken. It shuts off at random any advice possibly I have done everything from DFU to updating. It wont shutdown until ios is actually booted up other it can make it through the update cycle without running into anything. I only use plastic tools could’ve this been my fault or do you think its the screen or prior damage from when the kid fell with the ipad.
