I don't know if this is just an issue I am having...   Since Sunday evening all channels on freeview (Terrestrial - pinehill transmitter) are pixellating & freezing then cyling through psychadelic colours then return to normal every few minutes, audio is not affected.

If this is just my problem, what is the likely culprit, I have relatively new RG6 cable from antenna to 1 splitter, then slightly older cable to stb,  I plan at this point to replace older cable asap but I'm wondering why it was fine up until the past weekend, nothing catastrophic has happened...

Any ideas?

Mark.
