I have two problems:
My TV (Samsung LCD HD 720P) and HD DVR (Motorola DCH3416) have been playing nicely together for 3+ years. We had a few power outages last week, but everything came back on with no problems. Yesterday, the cable was fine in the morning, but when I come home, I get "No Signal." I tried getting the refresh signal (twice), a new HDMI cord, unplugging/recycling all, and still, no signal. I checked the HDMI ports with my DVD to make sure it wasn't my TV and it worked just fine.
I was finally able to use component cables to get the cable back up, but the HDMI port still isn't working. Has anyone ever had this happen? I'm going to swap the box tomorrow and see if that works. If not, I'll have the tech come out.
I've learned that if the tech determines that the problem is not comcast-related, they charge me $33 for the visit. I, for one, have a serious problem with this. I am not a technician - how in the world will I be able to determine the cause of this problem? Sure, all points to it being a comcast issue now, but what happens when the tech decides it's not? I'm stuck with no service and an extra charge. How is that good customer service? The kicker is I wasn't even told about this charge until I called back to reschedule my appointment.

You are welcome to swap the DVR at the local office to avoid any charges. Take the remote with.
You have tried all the proper steps as long as you have unplugged the TV in your troubleshooting steps.
There is no other reason other than it being the DVR.

I am havening the same exact problem right now! I turned my TV off last night and this morning when I turned it on my screen was blue. I called comcast Tech support and the woman I talked to could not find out what was wrong. After a few checks and about 45 minutes she cut me off and put me back in line.
The next Tech seemed to know what he was doing and after several checks he determined that the comcast box was bad. He suggested that I go to my local Comcast office and get a new box and a HDMI cable. That I did I start to walk up to the counter and the woman get's up and leaves. After a brief wait I asked the other person if she was coming back and she told me the woman was on break. Now here is another 20 minutes shot.
I take it home and hook it up and it will not work either. The programming will not load and the TV has no picture.
I call Tech a 4th time and this one is very rude to me. I am told that I don't know how to hook up my TV and that I should call the maker. But, I do know how to hook up my TV. I have all the manuals. I am on line with this Tech for another 45 minutes and she decides that she needs to send a repair man to fix the problem. Here is my problem (same as yours) she let's me know in no uncertain terms that if it is my TV I will have to pay a service call. I was able to get my TV to work with a AV2 hook-up. Does any one know how to check the HDMI on the Comcast box?

I have had the same problem with the HDMI not working. Everything was working fine in the morning and later in the day I had problems. The problem the had was--either: You see all the channels but no sounds. (now my Tv had 4 htmi inputs) so I checked my bluRay player, that worked, my Netflix-that worked. So I switched the cable wire to a different input and still no sound, so I plug the cable into the netflix input and that didn't work. I was like what is going on.
So I hooked up the Component cables and there, I get sound and no picture. ..
Long story short...cable comes swaps box..and still has the problem...checks wires..
What needed to be done was to completely shut down (unplug the cord from the wall) to Tv and cable box for 5 minutes) to reset it...I guess the cable box is sending out too strong of signal and needed to reset the html input. When I did that everything was back to normal, I mean cable box via the HDMI with Sound. Hope this help anyone out, I did this on my part by chance because the cable man had no clue.

Solved my problem. I was sure it was not my TV, so I took it to my neighbors and plugged in to their Comcast cable. Wow, the picture came on and was great. Called Comcast and explained what I had done. They checked my service and I did NOT have HD! It had been shut off by mistake. I explained what all I had been through for 3 days and he kindly reduced my bill for 12 months. This I was happy with.
