Have had a VIP 622 running for two years with no problems. All of the sudden the TV2 feed to my second TV doesn't work. Checked to insure that the output channel was On-Air 60 and the second TV was set to 60. Then I ran the cable from the TV2 output to my main TV. Still nothing.

That leads me to believe that there is something wrong with the output board for TV2 in the receiver. Seems strange that everything else is working fine. Any experiences here?

I had exactly the same problem so I changed the modulator channel and now all is good again. I switched it from 60 to 80.
