I found that the suggestion for Mitsubishi was good. I have a Charter Cable Universal Remote OCE-0053A. I went through all the Mitsubishi codes and found the 363 code worked for programming the TV to function correctly! It turns it on. The mute button changes the TV input between the options on the TV. It will not control the DVD player integrated in the TV.
We are considering purchasing a Universal Remote for our living room TV and I was hoping to us the Cable remote for the Polaroid.
I guess I'm keeping the OEM remote from the TV for now.
