Hi, we have had this issue for a very long time now. On our TV, often live events like sports, but can be on normal tv too, the picture pixelates and distorts randomly..
We have had many engineers out, problem has never been solved. I believe it to be a Signal issue, and something to do with the cabling from the road, that goes all the way to the tv, something wrong with one or more of those cables
We have had new boxes, new cables (internally) and multiple engineers out and no fix at all
My dad wont do anything about it or phone up , so im posting here for any advice
