I recently aquired a SR4400 that someone had bought from hifi.com. I was in the process of setting up the reciever for my HT setup when the remote stopped working. I frantically tried things to try and get the reciever and remote to work but have failed. The buttons surrounding the directional buttons have stopped working. These buttons include the OSD, Menu, set up/T. Tone, Menu Off buttons. Also, the power button does not work either. When I press the power button The small light in the top right corner lights which I assume means a signal is being sent. This does not happen when I press the other buttons I mentioned. I have tried reseting the reciever but that has not helped. I would appreciate a reply. Also, I am curious to know if there are other remotes that are compatible with the SR4400 such as the RC5200.
