Recently I have noticed BBC1 HD and BBC HD not working and message no/bad signal. Checked the frequency 10.847V for both channels. Checked signal in dish settings strength 85% quality 40-50% and very erratic, the power bars in red (poor reception I think). Is this beacause the channels have moved or is it a problem with the dish or lnb. By the way still using 119p not had time to upgrade. Any help at all would be much appreciated.
