Sound, but no picture on HD channels

So, I have sound, but no picture on HD channels... The nonHD channels have picture. Any tips?

Are you paying for HD? Usually that’s what happens when you don’t

Hmm, I don't know! If that was the issue, the sound would still come through on those channels?

Do you have an HD box? Have they ever worked?

Exactly which model box do you have? This almost sounds like your area finally upgraded to MPEG4 video, and your box doesn't support it. I thought Comcast had upgraded everybody by now.
