My HR24-500 would not respond to my Harmony One yesterday, so I tried the DTV remote, and it would not turn the unit on either. Did a red button reset, and has worked fine since. Anyone seen this before?
I had the same problem with the remote yesterday on my HR24-500. I had it set to RF and it's been working fine until yesterday. I changed it back to IR and it's more responsive now. I didn't see any software updates or anything, the receiver just stopped taking commands from the remote for whatever reason. The remote was fine because I could control the TV.
