When you say channel are you talking about a channel on the TV or the remote code 2? There is a difference and I would suggest you look in the owners manual and go through the steps to program the remote and receiver to a different remote code to assure they both are the same. Just becuase the IR part works has nothing to do with the UHF remote code.telekol said:the channel is set to 2, as i said the ir works fine so its not likely the remote, but you never know
