You bought a used TV, it may be broken in it doesn't accept IR commands. It maybe the reason original owner got rid of it? You can get a true Roku Wifi voice remote from Walmart and see if this tv can at least pair with wifi remote. Cost of of wifi remote is either $20 or $30 at Walmart, Amazon or Roku website. Any thing cheaper is an IR remote too, which you TV has problems with.
The remote was working on it until I reset the device.
n8rthagr8r, I'd still suspect the TV. Can you get any response out of the TV if you get right on top it? The IR receiver is usually right next to the light on the front of the TV. You can also see how strong a signal the remote is sending by pointing it at a digital camera like the one in your phone. The brighter the flash/glow coming from the end of the remote when you press button the stronger the signal. There's not much else you can do since there's no way to roll back an update and if it was a common problem we'd be seeing more reports. Does the remote have other TCL codes you can try?
