When you try change channels etc, what color does the LED flash on the remote? It may be set to TV only instead of Optik.

Were you able to find a fix for this? I am having the same problem 😞 I have changed the batteries on the remote and the light on the box still flashes green (as usual) when I press buttons but nothing changes on the actual TV.
@KatR199 power cycle the Optik Receiver. Remove the power cord from the back wait 5 seconds and re insert it. Let the box re-initialize and see what happens.

Or, if your PVR is as difficult to access as mine, press and hold the power button for about 10 seconds.
Failing this as a solution, you may need to reprogram your remote. Let us know.
