Fox News channel pixilated and audio distorted.

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 may seem odd that only one channel is affected, but techs see this every day.

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.

Be aware that if the Comcast 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.

Hi there, @JGard911,

We wanted to reach out and touch base with you to make sure the pixelation is no longer happening. If so, can you please private message me your full name? Thank you for posting to our forums.

Well ComcastMartin, the same issue of pixelation and distorted audio on the FOX News channel normally occurs during some sort of high interest social discussion one of the panels are having. I can change channels and all the others are just loud and clear. This started back in the days when President Trump would speak. Yes, it is very funny. But  now whoever or whatever was causing the issue of distortion has broaden there horizons, because it on every channel across the board. But mainly wait for a hot new topic to be discussed on Fox Channel 5pm The FIVE and you'll experience for yourself. 

As an old retired telecommunications / facilities Technical Control there's many ways to disrupt a signal. The Comcast folks just last month placed a new shielded cable from my house to the pub (which is in my yard).  The first tech noticed there was a filter on the old existing cable and commented saying that's old and shouldn't be there, because it's no longer needed. Great. However; the new existing cable still has filter connected to it, only it''s a new filter. I was not around when the tech's installed the cable, nor did they make contact with anyone that was home at the time.

Oh, did I mention, I've run every test, checked every connection and noted it doesn't matter whether or not I'm getting the signal via an Ethernet cable or via  wifi signal, pixelation and distorted audio is present.

How can an fiber optic signal be singled out and / or simply distorted? Disrupt the signal at it's source. Ha, that would be to well protected. Isolate and capture the signal somewhere along the mediums path. In the old Cable connection days, freq where pushed through filters either and/or at the company's  pud and/or at users coax cable signal output point. But those days are long gone. So, now... where is that single signal (a channel) being controlled at? The box. The cable company box which is connected to the TV. 

TV, which actually today SMART TV is just a computer with a massive screen.

Oh did I mention, I have several SMART TV operating off of several boxes and when the FOX NEWS channel gets scrambled, it's on all TV's. [Edited}

Have a good one. Cheers.
