My table screen displaying as mirror images

My table screen displaying as mirror objects and then i have connected with HDMI port to TV then it displaying proper image on TV screen, but not able to do anything because am not able to do with touch screen because everything is mirrored so not in a position to touch the right key/button. I stopped using the Tablet for few months then now i have tried to open the tablet(recharged) but it is not working. Any help is very much appreciated.
