My DishTV T1050PVR is doing OK on TV1 - TV3 but Choice is very bad. If I play with the power in cord at the back I can sometimes get it to go but sometimes I get just the picture and not the sound and other times the lock light flickers and I keep missing bits . I tried a different power cable but it didnt help at all. Any ideas?
It could be related to your UHF aerial, it could be misaligned and out of direct sight from your local transmitter. This often reduces the reception quality on some channel groups.
You could at first, try a retune and see if the channel loads up without any interference, otherwise you may need to get someone to realign your aerial.
