Hi, channels 101, 102 and 103 intermittently keep pixilating. I’ve tried box connections, disconnecting box etc but as it’s happening on all our boxes I can’t imagine they have all developed the same fault at the same time. Running a test proves no issues and can’t get through on the phone. It’s been happening for weeks now. All other channels seem ok, and the bbc and itv HD channels don’t seem to be affected as bad but it does happen on those sometimes too. Any help would be appreciated.
