Tonight while watching tv the screen froze but the audio still played, I tried channeling up and down and the guide but every picture that can up was stuck. I turned off the receiver and restarted it but when it can back up all my channels are now on parental lock and some of the menu options are missing so I’m unable to even set up my pin for parental controls to unlock them. What can I do to fix this?
Try a non-disaster recovery and if that doesn't work, last resort, disaster recovery. These are described here. Note disaster recover is a factory reset. If this is the dvr you will lose all your recordings (but not the scheduling). On the other hand the parental control pin is also reset to the default (1234 I think).
If these don't fix the problem it's time for a new dvr/receiver. Call tech support for a replacement (800-288-2020).
