Okay, this problem just puzzles me. I've double-checked the remote id on my 921 to make sure it matches my remote, but for some reason the receiver does not respond to any buttons that I press. My Sony HDTV however does respond to the TV assigned buttons. Is there any way to do a hard reset on the remote to restore it to factory defaults? Or is it possible that this remote could be damaged? Any help would be greatly appreciated!
