When first installed the remote worked fine, but when I tried to select the BluRay and watch a movie, I couldn't select the correct input. I figured out I had to keep pushing the Input button multiple times, but when I tried to go BACK to cable it wouldn't return. Channel 3, the cable input channel, won't come up. Or when it does for 1/2 a second it immediately reverts to ch. 4. I read in another thread that you can restore it to its initial state with code. Please note that I am an ENGLISH TEACHER and not familiar with all the lingo. TX
