I do not have an answer but I have a similar situation. My screen was broken so I installed a new screen and screen protector, but when I turned my tablet on, it was not responsive to my touch. It also gave me a message about the battery being in an abnoral state, so I opened it back up and found that the speakers may have been misaligned, so I re-installed the speakers in the back panel and reassembled the tablet, but then, the screen went to the opening page but I could not unlock it because the screen was unresponsive. I did get my weather program to come up without unlocking the tablet. I don't know where to turn from here.
