Hi did as suggested when into settings some channels has no signal strength or quality in input 1 and some in input 2. How do I correct this.  Thanks

"No Satellite Signal" usually indicates an issue with one or more of the following:

• The Dish is misaligned
• The Tuners in the sky box
• The input sockets on the Sky box
• The plugs on the cables
• The cables themselves
• The Sockets on the dishes LNB
• The dishes LNB has gone faulty for the connections the box is using

You may have to call out sky or a 3rd party satellite/aerial company

Note: If you have a communal dish then this is maintained by your landlord/building management and NOT sky
