So yesterday my DVR set-top box (model QIP6416-2) stopped accepting any commands from the remote control. I've not changed a single thing in my component setup, which has been configured this way for a couple of years, working fine. The remote just stopped working all of the sudden.
I use a universal remote programmed with commands for the DVR (and always have). I pulled out the original remote for the DVR (batteries are good) and it didn't work either. Both remotes control other components with no problems whatsoever.
I tried several things to fix it. I unplugged the box for a few minutes then plugged it back in. I reset the box through the on-screen troubleshooting option. I turned off all other components and the TV to rule out any IR interference. I cleaned the display to ensure the IR receiver wasn't blocked. I've tried both remotes from only inches away. None of this worked.
The little LED in the lower right corner of the display that normally lights when a command is registered does not light. The box apparently just isn't registering any signals. Operating the DVR via the front panel buttons works fine. Aside from the remote, the box is in full working order.
Any help on how to fix this?
Thanks,
Mark
