Weird one with "no satellite signal message"

[MartinfromSurrey]

Ok for about 2 weeks Ive been having an intermitent pixelation then "no Sat sig" message on all channels in perfect wheather.  Had the enginner round who checked the cable  & changed the LNB.  It was fine for about 24 hours but now the blue no sat sig screen  has returned this time for exteneded periods.. On its last occurance Ii did a bit of investigation and this is the odd thing

 With both Satelitte cables connected blue no signal screen

Remove LNB1 cable, no signal..

Replace LHB1 cable but remove LNB2 ...picture instantly returns  replace LNB2 cable and picture goes again.

I know it sounds like the dish/cable but the cable has been checked for shorts and the LNB changed..  could it be the box?

Also If i just run with one LNB cable I assume my recording options are limited.

hi @MartinfromSurrey 

It does sound like one of the cables or possibly one connector is at fault.

On SKY Q each cable carries the channels on a different polarity - Horizontal on one & Vertical on the other.

Is it possible that when you are seeing the 'No satellite' message you are have not tried a channel on the other polarity rather than a total loss of channels ?

BTW the signal strength indicator on SKY Q only shows the status of a single channel set in the engineers menu & not the channel you are watching.

Thanks..  Just to clarify Im now watching BBC with one LNB attached and its fine, but as you suggest I cant recieve C5 for instance but if I plug in the 2nd LNB all channels disapear.

Just out of interest can you try swapping the 'working' cable to the other SKY Q input (on its own) and see if you still get  a signal- which I think should indicate if it is a cable or box problem

Thanks.. Think you right it must be the cable, the 'working' cable works in both inputs on its own , the "faulty" cable on its own doesnt work in either, however  when both cables are connected to the box,  ALL channels disapear, ( this was intermitent and just for a few seconds but now seems permanent.)

Thanks for escalating this. We’ve sent an invite to chat.

Many thanks for that - I am guessing you will need another visit from an engineer.

Anyway,   I have escalated your post to SKY who, hopefully, will be in touch to discuss further & maybe able to arrange for a visit (Edit - I see they have already invited you to chat in the time it took me to post)

Please see this link re the escalation and what you might see:

If you are using Safari I believe you must make sure that 'Hide IP adress' is not checked in settings to be able to see it - if you have difficulty finding that setting then may be try accessing here with another browser

New cable fitted  all fixed 😀

Looks like a combination of rodent damage and 15 years of weather damage.
