pixelation

I was checking the forums to see if anyone else has been having this issue recently.  While it isn't affecting all channels, one I watch a lot (MeTV) is basically unwatchable right now due to frequently pixelation and audio drop outs.  It might be fine for a few minutes but then there will be frequent drops in signal, sometimes long enough to cause my box to display an error message that there is no signal versus just the picture and sound breaking up.

Is it all channels for you or just certain ones?

Channels keep pixelating ...

Pixelation happens when the signal for the channel you are trying to watch is too weak or has too much noise. This is most likely due to a poor connection between the box and Comcast's network, usually in or near your home. It might also 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 "Xfinity" app) but those possibilities are much less likely.

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 (approx. $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.

Yes this issue is still going on-for almost 2 months.  Comcast is not telling anything about when it will be fixed.  Yet, they keep sending a "full" bill.  They "will" be refunding a good portion of my bills or I have no choice but to contact the FCC.  I have been very patient, they say they will update me but NEVER do.  I am not trying to be nasty but 2 months with still paying my full bill is just unacceptable.

I’ve been getting same pixelating issue for the past few months. Changed to a brand new box and new high speed hdmi cable. Still pixelating.  Doesn’t happen using the app, but until such time as the app allows direct tuning of channel numbers and voice commands, it is not an acceptable option, especially since I’m paying for the box. FIX THIS ISSUE!

They finally admitted the problem was outside and moved my wires underground. I haven't had pixelating since they did that. I still haven't received the $12 they feel I am worth let alone a credit for the months I have been calling about the pixelating.
