I have a TCL Roku TV and it came with a voice remote. Today we turned the tv on with the remote and now it doesn't work. I know the batteries are ok, but put in new ones just in case....nothing. So I thought I would try to pair it again. It shows that it is there on the tv menu, but it doesn't know the firmware or the battery level. When I pressed the pair mode button, no light and it won't go into pair mode. We did grab another Roku remote and pair it. So what is wrong with the remote that came with the TV?
