certain channels missing ???

[GIM]

Hi, I have a skybox f5 and a openbox running at home, but on the one downstairs all channels are working fine but upstairs sky showcase will not work also sky1 will not work but sky1+1 will work, I have tried different channel list but still the same, any ideas. thanks

Being new to this, I have realised that I might have asked something that against forum rules, if so please tell me and I will repost. thanks

Try disconnecting the LNB cable from the working box & see if the channels reappear on the non working box.

If they do, then you may need the "no signal fix" from Ebay.
