Did you try these:
[Link: remotecentral.com]I tried a Google search on your model but got no hits-did you leave out a digit?. Most seem to have 5-digits. Also Proscan and RCA are both owned by Thomson and use the same IR protocols and codes. You might look at the RCA TV's that have similar features.
If you have an HD tuner in the TV that does OTA and DirecTV it probably responds to the discrete commands posted for the RCA DTC-100 HD receiver.
