Problems with 722

[KHJ0728]

I have been having with my 722 as of late. On some SD stations on one tuner the signal comes in but is pixelated and the sound is as if it is on the brink of losing signal. On the other tuner the same station is fine. Also i have been getting alot of error messages telling me to either change the channel or contact help. I have also noticed one day where one tuner was dropping the station on a HD channel while the other tuner was showing the program fine. Any suggestions?

Try deleting the channels the channels that lose signal.

Could be a bad separator or connection into the tuner (Sat*) input.
