I have an HR21-100 and while trying to reset the remote with the 981 code the remote stopped working. The remote works on my other receiver, which is an HR22-100, but that remote won't work on the 21-100. I called technical support and the girl there said she would send me a new receiver because she thinks something went wrong with the receiver. I hope this makes sense. Anyway, while I probably have a window before the new one ships, does anyone have any suggestions on how to fix this problem? I did a red button reset, by the way. Thanks.
