Try using an RCA cable directly from the receiver to the TV to see if you are having the same problem. If you get a clear picture with the RCA cable, the coax port is bad on the 722k. Please let me know. Thanks.

I brought tv2 next to tv1 and ran the rg6 cable directly from 722k to the tv. Only slightly better on cable 73 and air 25. I tried a different cable with no change, so I'm guessing it's in the 722k unit somewhere. Any other thoughts before I call for service?
