Hoping for help….

Firstly I should point out I have. Sky+HD box and I would be pretty comfortable around the system, cabling, dish etc. I have been able to resolve a number of issues over the years on various boxes, however this one has me stumped and I am interested to hear if anyone has seen this before?

So my system is on my home and I have my own dish. Both my incoming Coaxial cables are sound and have been tested. When I connect them to the box and start it up on Channel 998 for instance, all works fine and I have two strong signals showing in Settings. 
But if I change to Channel 104 or 108 and numerous others, I immediately get the "Your Sky+HD Box isn't getting a satellite signal" message. When I now check settings I find that Input 1 has completely dropped out and I only have a signal on Input 2. If I return to a channel that is working I again go back to Settinhs to find I again have 2 Strong Inputs....????

I have carried out a number of Resets, Restarts and a Rebuild.....to no avail.

I am perplexed and would be grateful for any ideas or assistance people may have to offer. Thanks in advance for your help!!

"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

Hi Annie,

I appreciate your response but I fear I may not have adequately described the scenario....for a large number of channels I have 2 strong signals when I check in Settings. But there are certain channels that have the "No Sat Signal" message, and when I check, I find that for some reason the signal on Input 1 has just disappeared. I skip to the very next channel and I again have two strong inputs. 

This likely discounts the possibility of Dish alignment, cables and Lnb's as these are unlikely to alter simply by changing channel. 

I can record on a channel I know to be working for instance, while watching another. I believe this also would suggest that the inputs are working correctly. What I don't get is how I put 1 vanishes on certain channels?

Thank you for taking the time to reply.

The channels are spread over a cluster of satellites so you can get a loss of signal on some channels and not others, you'll need to check the transponders the failing channel are coming from to see if there is a pattern

The LNB could be faulty as some frequencies could stop working but not all, a failing tuner could also cause this kind of issue

Best get someone out to take a look
