If you are using the internal Freeview of the TV then it's possible there is a fault with just that.
The "fix" for that would be to get a Freeview box and see if that works.
There has been no mention of any other TVs in the household, if there are any other TVs do they work all right?”
I have a couple of old Tv/video combis that my children used to use in their bedrooms many years ago. I still use them to play videos on. One had a freeview box, so I brought that one downstairs for the grandchildren to watch their favourite videos (I'm keeping their feet on the ground, they love 'old' stuff

) But not had the patience to continue connecting up the top box when it didn't work the first time, really must give it another go as I too thought it might indicate where the fault lies.
I have my cheapo Technika TV in the lounge but want to put it in my bedroom and have a slightly larger one in the lounge, so want to buy another TV anyway.
The engineers who came to try and sort out the problem were the same ones who installed the aerial in the loft many years ago, so hopefully they gave me the right advice. Does seem strange that the Tv has worked fine for about 6 years then at the end of last year the pixillation/sound skipping began out of nowhere.
My demands are small - not even hooked up to wi fi yet, still use the wired connection on my laptop, Just want a TV that doesn't pixillate!
Thanks to all who responded, I am trying to assimilate all the info.
