Pixelation Problems on my tv
This is sad....all this money us customers have to pay for our cable and we can't even watch live television because it's pixelating. I'm trying to watch the opening ceremony of the Olympics but I can't even read the words let alone see who's country are on the boats/yachts. Even the audio is skipping with the pixelating. This is my favorite time of any year is to watch the summer games smh. It's the network from Xfinity and theirs nothing a tech can come out here to do about it. We've been down this road before. I guess I'll be watching the Olympics like this..It is so disappointing. Changes will be made with cable provider very soon.

We have the same pixelation problem. The Giants game on the NBC Sports Bay Area channel was unwatchable today (Sunday) on our TV. A message from Comcast says they see no problem with our connection. We have an appointment on Tuesday for a technician to come and check things out.

Since Xfinity upgraded my moden I've the same problem. I changed boxes, I checked cables, etc. Maybe the new modem is not compatible with the boxes.

We have been struggling with this pixelation/frozen image issues for months. I have called several times and they claim to fix it but then it comes back the next day or so. Now, thanks to their automated assistant I can spent an hour trying to get to someone to pick up where they left off after running through all those things again and again. There should be an easier way to get to a live technician, especially after calling in for the same problem. We have replaced the DVR and the HDMI cable. We have checked all the connections. We have rebooted and had them reset things. I really believe there is an issue with their equipment outside.

It's been 3 days since Scott (Comcast tech) stopped by and worked with me on the pixelation/tiling issue and so far since then, zero pixelation.
We weren't experiencing any severe pixelation when he arrived, but I had a short video to show him. Immediately, he said that it was classic tiling and got busy looking for the reason. He already knew that it was happening on the local channels and explained the reason why is because of the narrow frequency band that is used for that group of channels. It's easy for them to overlap.
The first thing was to check the inside cable connections, and I don't mean just the connection at the wall outlet and the TV box but behind the wall plate where the outside cable comes to the room. He found that connection was loose. That's no surprise as it was installed 25 years ago and had never been checked. More importantly was the connector on that cable. He pointed out that it was unshielded which could allow radio signals in. This was common on those cables and considered adequate back then when all we had was basic cable. He cut that connector off and replaced it with a shielded one. Upstairs we found the same scenario and he did the same replacement.
We then hit the outside box attached to the house. Again, all of the cables had the old, unshielded connectors. He found that the cables were very corroded and most likely caused from water leaking in. He had to cut them back a couple of inches to get to clean copper. He replaced all of those and while at it, he replaced both splitters which were also from that era. He also found a stray one-foot-long cable connected to a splitter and just hanging there. He said that piece of cable could act just like an antenna attracting rogue radio signals adding to the noise or interference.
Once completed, he checked the signal several times a found no interference in the lines.
As mentioned, we were not experiencing any pixelating/tiling at that particular time so weren't able to determine if any one cable or more were causing the interference. Even if we had, it would have been prudent to go ahead and replace all of the old connectors. If one of them could be the culprit, then the rest were also capable of causing future problems.
Scott said that he was more than 90% sure this would take care of the issues, but we would have to monitor the local channels to confirm. If we had any continuing problems, he said he would come out and take a look at the rest of the cable runs. I have kept an eye on the local channels throughout the last three days and so far, so good.
It took Scott about 20-30 minutes to complete all of the work. He lives not far from me, so it was great to have a tech that was not only familiar with the problem but with what local stations were involved. It allowed him to zero right in on the solution.
I'll repost if anything changes but for now, I'm totally satisfied with the results.

To XfinityMarcus: I have no additional questions or concerns at this time. I will continue to monitor to ensure that it is indeed resolved.
I do ask that Xfinity share this information throughout your company.
I’ve seen many posts on these forums from around the country going back years. They spoke of many frustrating experiences trying to find a solution. I never saw a single mention of the older unshielded connecters on the cables coming from the outside box.
It was the very first thing the tech looked at and was such a simple fix.
