Freeview reception issue

Apologies ... was posting in a rush.

Certain channels ( ITV2+1, QUEST, ITVBE, CITV) are interfering on my TV. Picture break-up and glitchy audio. But I don't know the cause and how to fix it. I have even bought a new aerial cable and it still didn't work. Is it to do with the TV itself, the aerial itself or 4G? I am out of ideas!

Just point your aerial down, facing the table. It works for me!

Any hdmi anywhere near? ....keep the aerial cable away from hdmi

Yes! that maybe why! I will try all advice.

Do you have a booster installed by any chance?

Is it an older TV you have? I was using an older TV (not sure how old, but it still automatically checked for new analogue channels every retune) that had issues with exactly the channels you've listed, but I got a newer one and it worked perfectly with the same aerial cable.

Just check the EPG at Ch 800 or above, are there duplicate versions of those channels you're having problems with up there ?
