I have a TM 5402 on a motorised dish and a TM500 on a static dish at 28.2.

Recently I've lost a few channels, Setanta & BT Sport etc and in the past a new scan of the boxes would bring them back. This time they've not come back and it's not just on the one box its both of them so now I have no idea what's going wrong.

On both of the boxes all the working channels have ~90% signal but when I select the non working channels the signal drops away to 10%

Any ideas?
