Had a VIP622 for a number of years and have loved it. Just recently it started to have a 2 to 3 second lag when using the remote and a system reboot would correct it. The other day I tuned to an OTA channel in the guide and the receiver rebooted. Now every time I go to an OTA channel it reboots. I went into the menu for local channels and when I attempt to scan for locals the receiver reboots. I changed the cable from the antenna to the receiver, still doing the same thing. I hooked the cable directly to the TV and received locals without issues. Time to replace the VIP622?
