My living room TV screen just fried again!

So, my living room TV screen just fried again! It is the ONLY one connected to the main Xfinity box. Here's the thing: this is the second TV in 10 years (one on my account, one that was on the same account when it was in my mothers name) that has been located in the living room on the main TV box to lose its screen. They still power up, but the screen is fried. The kicker is that every time I get a new TV, I buy two of the same brand—one for the living room and one for the den. Sometimes I get three (one for the master bedroom). Last time, it was two Westinghouse TVs, and the time before that, three Samsung TVs. Now, here's the other interesting thing: the TV in the den gets like 10 times the usage, but they are only hooked up to video game systems, and my Mac for video editing computer for the second display. They are not on the Xfinity box or cable line at all. The TVs in the den get significantly more "on time," for sure. The one in the bedroom is on a ROKU for watching Netflix and Disney+, There is a one of the small xfinity boxes on there but its never really used. ALL of the other TVs are working fine. They are all still working great, but each one of the same exact brand and model that was in the living room connected to the main Xfinity box has died within a few years. The last time this happened, we replaced the surge protector, so there's no issue with power there. Also, my buddy is a master electrician, and he has checked all our power; we are good. This is the guy who is my studio electrician, the one who understands how to filter out 50/60 Hz electrical noise in the power, so I know there are no issues there. I have also been reading a lot on the Xfinity message board as well as on Xfinity Reddit posts, and it seems like quite a few Xfinity customers are asking similar, if not the same exact, questions about the problem I am experiencing. What can you do or suggest to remedy this, as I am now out yet another TV?
