Recurring pixelation sometimes occurring along with momentary loss of sound!

@XfinityDena​, this issue popped up last night during the live broadcast of the MLB All-Star game on Fox. I believe now, as I did when the problem arose back in May, that there is a direct correlation to the weather conditions and the problem. All day yesterday and last night we experienced periods of heavy rain in our area and suddenly the pixelation, along with a temporary loss of audio, began.
Today it is dry and sunny, and I've not seen the pixelation.
Previously back in May when I contacted Comcast/Xfinity to get repair service scheduled, this issue was affecting everything: broadcast live TV channels, cable, and DVR recordings. The issue persisted for a couple of weeks before I called Comcast for assistance.
I told the service tech who came in the middle of May (a young kid recently hired by Comcast) that I felt like weather was the culprit and that maybe the cable line needed to be replaced with a new one, but he said his diagnostic equipment showed otherwise.
I want this remedied, and I request a credit of the $80 I was charged for the previous "service repair" I was charged in May (2025). My patience is at its end.
Please respond and help.

Charges may apply for service visits when Comcast-owned facilities or equipment rented to you by Comcast are not the source of the problem with your service. For instance, you may incur a charge for a service visit by a technician to your home in order to diagnose and repair problems with the In-Home Wiring used with your Xfinity services, or for the diagnosis of issues relating to the connection between Customer Equipment and your Xfinity services.

What troubleshooting have you completed since the issue started? @user_b318db

I am having the same problem with pixelation on certain channels for the last 3 days.  We have had this before.   It is not our equipment as it was just checked not long ago for another issue.  Also numerous people in neighborhood have same problem.  Please fix this.  

Pixel glitching on MOST of our channels now.  This problem started about 6 months ago and has gotten steadily WORSE since then.  Have called Xfinity/Comcast more than once about this issue and have found them both disingenuous about this WIDESPREAD problem throughout Salt Lake (dishonest, really, putting the onus on the customer!)

Customer Service (HA!) asks us to jump through hoops at home to “fix the problem,” a TOTAL WASTE of our time, has the NERVE to try to SELL us a STILL more EXPENSIVE PRODUCT !!!!! Keeps us on the phone for more than 1 1/4 hours, solves NOTHING !!!!!  For 6+ months of terrible, unviewable pixelated programming on a majority of channels (for which we pay $200+ per month, we are offered a $5 credit and NO RESOLUTION to the PROBLEM.  Is this some sort of sick joke?  EVERY Comcast 
/Xfinity customer who has experienced this nightmare should receive a full refund for the last six months of horrendous service and a thorough apology.  This is OUTRAGEOUS!!!!!!
