Extreme pixelation on CNN 842 and Fox News 841

Is anyone but me experiencing this problem. Has been happening over the past 24-48 hours at my home in SE MASS.

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 cable box and Comcast's network, usually in or near your home. Less likely, it might be because of a bad box or a problem at Comcast (check https://www.xfinity.com/support/status/, 1-800-Comcast voice response, or the "My Account" app).

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, 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 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.

Been having issues for days, only on certain channels. Read where an update Xfinity sent to X1 boxes was causing issues for some customers. No, it is not always a cable/connection issue, but all of my indoor connections were checked, X1 box reset, reset signal sent from Comcast to reset box, blah, blah, blah!. Two of our 4 LOCAL channels are pixelating too frequently to even watch. 

 

What may help temporarily, is to manually change the resolution on the X1 box. The box is probably set to automatically autotune to the "BEST AVAILABLE RESOLUTION" based on your television.

 

1 - Press "exit, exit, exit, 720" on your X1 remote. This sets the resolution to 720. THEN ...

2 - Press the "XFINITY" button on the remote. Click the "GEAR ICON" (Settings), click "Preference", click "General", choose "Prefer Best Available Resolution", click the "ENTER" button to turn off.

 

I personally went back into settings and changed my resolution to "1080i". So far this seems to be working for me. We have a technician coming out next week. Maybe we can get the issue resolved and go back to 1080/60.

 

Hope this helps sombody!
