Pixelated, garbled picture
For the past month or so, we've had problems with experiencing pixelated, garbled pictures on several TV channels. I've tried resetting our X1 box, but it doesn't help. This problem seems to have been getting worse the past few days. It's easy to see on the pictures I took last night how bad it's gotten.

Pixelation happens when the signal for the channels you are trying to watch is too weak or has too much noise. This might be because of a bad cable box or a problem at Comcast (check https://www.xfinity.com/support/status/, 1-800-Comcast voice response, or the "My Account" app) but is most likely due to a poor connection between the box and Comcast's network, usually in or near your home.
Troubleshoot by checking all connectors for corrosion and tightness, and by looking for damaged coax cable. Running the cable through a surge protector, a defective splitter, or too many splitters can cause signal problems as well. If there is an amplifier in the line make sure it's getting power. You might also try unplugging the cable box/DVR/digital adapter power cord for a minute or so.
If you can't find the problem or you'd rather have Comcast take care of it and an employee does not respond to your message here, call them at the phone number on your bill or 1-800-Comcast, or use one of the options on https://www.xfinity.com/support/contact-us/. Ask them to check the account setup and send a refresh signal to the box. If they can't fix the problem remotely, insist they send a tech out to identify the cause and correct it.
If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit ($70-$100) unless you have their Service Protection Plan (https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to a faulty Comcast cable box/DVR/digital adapter or anything outside your home, you shouldn't be charged.

I am also having pixelation! Has been happening for months now! Why should I have to pay to have this fixed when I pay almost $300 a month and cannot even watch or listen to my my programs! I have to go to the streaming channel to watch! Looking into T Mobile!

Pixelating pictures is a signal issue with your house or the local Xfinity system. Only a technician visit can get to the bottom of this.
Sometimes it resolves on its own , but if the issue is at the house or pole a tech is needed.

I’ve been having the same issue, and mostly on sports channels. Tennis channel, ESPN, etc.
It us getting unusable. It started happening when I switched to X1 4k cable box.

Same issue. Comcast tech came to the house and tested the signal. Signal was strong. He had no idea other than maybe replacing the cable boxes, but they aren't that old. Comcast knows this is an issue and they know it isn't always the signal strength.

ABC Network has been pixilating badly at our home for months, approximately 3 evenings @ week. Always in the evening/night.
Most times we just change the channel. Tonight, my wife is watching something on ABC and asked me to look up a fix. The most common advice is to unplug the X1 box and then plug it back in after a minute or two. Didn't work.
If this severe "pixilation" issue spreads to other channels, I'll be moving to one of those non-cable methods of watching TV that so many people have been converting to lately.

We started having this problem about a year ago - 2022ish (and still have it in August of 2023 - thus why I am here looking for help). Reading this thread, I at least don't feel crazy, but have zero hope a tech will be able to solve the issue (as no one has replied that a tech visit fixed their issue).
Things I have tried:
1) replaced cable box in 2023. (issue still present)
2) inserted a signal enhancer/booster (did not help and in some cases interfered with communication with xfinity) so nope, not that.
THEORY: I believe the issue is actually with the DVR "buffer". The "smearing" "glitching" carries the "image" from one recording to the next...not a signal issue as I am not watching "live" signal, but moving from one recording to the next and the "effect" carries over. Also, while watching live TV and in "pause" mode, when I resume playing, the...buffer??? sometimes skips forward to "live" - and I have to rewind back to where I paused the show.
WORK AROUND: I suggest you watch your DVR recordings via the Xfinity App (ROKU, Smart TV etc) as I noticed that recordings which had "glitches" on the cable box were FINE when watching through the Xfinity App connected to the SAME TV. I noticed no digital interference while watching live TV via the streaming app as well. If I switch to same channel on the cable box...glitches. Now I understand that sounds like a cable issue, but the signal is routed through the DVR box - for pausing live TV - so I think it has something to do with the compression or how the box records/buffers the signal.
The thing that sucks about the Xfinity App, is there is no preview while fast forwarding recordings. So, just remember that commercials are sold in 15sec, 30sec, and 1min blocks and COUNT the seconds as you FF. I've gotten pretty good at this.
I'm thinking of ditching the cable box as I believe there is something wrong with the manufacturing of the units.
No one has mentioned this.
Has anyone else run similar "tests"?

I have also experienced this issue for almost 1 year Nov/Dec 2022-Present (Sept 2023). I'm DONE!! Fed up! switching providers ASAP!! I have tried EVERYTHING mentioned above. Nothing works. We pay wayyyyyy to much money for this mediocre service. I may or may NOT come back in 2 years.

I had pixelation issues in 2022 and after contacting support multiple times, and running connection tests over and over, Xfinity finally sent a technician out. Turned out, water was somehow entering the cable lines running to the house causing the interference. I am noticing pixelation issues again, I am wondering if we are experiencing the same issue after the abnormally heavy rain we have been experiencing in the north east.

Same here - started noticing pixilation here in Boston, MA past couple of days…some stations not even available - get an error message - others like NFL Network just freezes…all the “fixes” do nothing. Annoying…will place a call this week.

I’ve been having this for several months now. I’m on my third 4k box and it still happens. They sent out a technician and charged me $100 for the visit, only to be told by the technician that the problem is with the box and it needs to be replaced. The new box has the same problem - I basically cannot watch anything recorded from the box because of the bad picture and sound. But it plays back perfectly from the Xfinity stream app. Also - the box frequently is very delayed responding to any input from the remote. After three boxes, I have to think the problem is something inherent with the box, and I don’t think I have been given three “bad boxes”. I also tried to lower the picture resolution settings (even though I have a 4k TV) but it doesn’t help. Anyone found a solution?

If you have your box plugged into an extension cord unplug it and move it closer to a wall outlet and plug it into there. You will see the difference IMMEDIATELY!!
Let me know if this works for you.

I am having the same issues now. Just started. Xfinity did some updating in our area and this is when it all started. Only get pixelation on live tv. Not DVR programing or streaming thru xfinity. No pixel problem when on tv channel menu either. Internet fine. I feel it is the box. It is the original 4K box. Should i make them replace it. They say it isn’t, but what else could it be. Bad signal would affect all not just live. Bad connections anywhere would affect all. Been around the block with this. Hi fidelity was my hobby and still is. I have had tech come out to my place many of times and the first thing they tell me is they have no clue what the problem is then $100.00 thank you and i am at square one again. Most of the time i know more then they do.
frustrated and thinking about going total streaming

I have been having pixelation problems for over a month (10/23). Called Comcast, and they walked me through steps to try and fix the problem. Didn't work! Called again and they sent a new box. Problem still ongoing. Called again. Still nothing fixed!

Same issue here. I'm right outside of DC. It seemed to have started 2-3 months ago. It only happens in my living room. The problem seems to go away during the week and it usually happens during football games. It might just be coincidence. I never had pixelation before. I also changed out the X1 box and it didn't do anything. I removed I think what's a MOCA filter and it seemed to help, but it's still intermittently there, usually on Sundays. I'm wondering if the Xfinity network is bogged down. Why is the signal weaker at times, when I think more people are watching. It's so annoying I might finally try another provider.
