TV Fuzzy (frequency)

[Mr Trophy]

Chaps

Wondering if some kind person can help.

My bedroom TV is showing a terrible picture (this is intermidin). I called this chap out who was in the house no more than 2 minutes (can't find it number) and said that the 4G was causing my TV to flicker, sharp sounds etc and changed the frequency and it stopped. Seems to have started again but no idea how to change?

Any ideas?

Order a free filter? You should have already received one if you're likely to be effected by 4G
