I am experiencing the same issue. Originally, the remote was setup with a 39" Insignia FireTV without noticeable issue. I then moved it onto a different TV(19" Insignia). After turning off the TV with the power button on the remote, I also use the same button to turn it back on. Shortly after it boots the volume quits working and the power button fails. The settings show the remote is set for w box technologies. I do a rescan, it finds my TV and corrects the issue until i power it off again. Annoying... unpair/repair, reset, etc. I haven't tried putting it back on the original TV though. I'll try that next chance I get.
