Sound but no picture

I have sound but no picture on one of my two TVs. I would suspect my HDMI/DVI cable, but it transmits video from my blue ray player.

I have two TVs, and have swapped the boxes, and each box behaves the same on that TV.

My set up is HDMI from X1 box to home theater amplifier (also have a by ray player hooked up to amp.) From there, output is a 50' HDMI-to-DVI cable to my TV. (I have also swapped the amp inputs to make sure it is not a circuit there.)

All was working fine. Plumbers working under the house running a new gas line today in the area of the HDMI / DVI cable. However, I see no cuts, dents, breaks, etc. And it transmits amp out signal from my blue ray just fine.

Rebooting X1 gives me the welcome, then black, then I get audio but no video.

Help!

I just tried this on my Samsung both for 720 and 1080 and I could hear the TV pause for a second to change but still no video. Could I have a bigger issue? Or need a new cable box?

that is usually an HDMI cable issue. did you try removing and reinserting the HDMI cable ends feeling and hearing the click as it locks into place?

Thanks It worked! Comcast needs to train their employees better. I called Comcast and they said it was a bad HDMI Port. They sent a new box. When I hooked up the new box it seemed to work fine at first but then started having the same issues again, especially at night. Was getting ready to waste my time and call Comcast again to send the new box back again and get another. Searched online and found this article. Thanks
