Not receiving services? full signal, black hole. please help!

[Fresher]

Hi, last night whilst recording a program my duo box decided to stop receiving services. I checked the sat finder and im receiving a great signal as before, i ran the manual service install but it returns no channel services at all, all the settings are the same as they were before the service drop. I then decided to try my all sky dish in my duo box and scanned for channels and it found everything? so ive been using that up til now. what could be causing the problem with my other dish?

Just to recap, the dish has a strong signal as before but when i run a channel service scan it returns nothing. The old sky dish works perfectly and installs everything fine. so its not the box. im running blackhole 1.7.8.

I appreciate any help!!! thanks again.

the dish that isnt receiving services is picking up a signal just fine, im getting around 80% solid signal.
