Pixels

[abstibus]

Recently my TV has started to pixellate (is that a word) on some channels (Channel 4 last night) ? I have never had this problem before. Is it the TV or the Freeview box that is at fault?
Has anyone any advice about what I can do?
Many thanks

Probably the Freeview box. Try rescanning all the channels.

Thanks, Count.
I'll try and see what happens. Is rescanning difficult? I usually get my OH to do things like this but he's away and will be for some time (no - not behind bars).
Will there be instructions in the instruction book?
I'm a total Luddite with anything like this - I can't even programme the heating, but I'm a wizard with the washing machine.

Has your area gone fully digital yet?

If not, your signal will increase by between ten and twenty times when they do, so the problem should be cured then.

Also make sure the lead from your freeview box to your TV is fully pushed in.

Thank you all for responding.
I reprogramed the Freeview box as Count advised, and so far (after 1 evening's viewing), all seems to be OK for the moment anyway.
