Sudden blue screen - no signal on any cable

 Blue Screen

We had sky + a couple of days ago and then we lost recording ability. I checked and discovered one input was not working. I rechecked each cable in a working box and confirmed we then had all 7 inputs active and working. No repairs just tightend some F connectors and replaced a loose connector.

Next thing we had blue screen on all tv's on all inputs.

If I switch on a get EPG for a second or two then blue screen.

I have done a soft reset.

I have 4 HD boxes and 7 inputs. They are unlikelyto fail all at the same moment.

I have a neighbour nearby who also lost his service to a blue screen so it is a sky fault. Has there been an upgrade recently?

Does the signal come via some uplink to the satellite which could be down?

The uplink is fine

 

where are these 7 connections? On a sat distribution box?

 

this is the Q forum by the way, not HD

There's no Sky fault.

So can you explain the blue screen? Loss of signal does not give blue screen does it? The box would still work but missing actual signals to dish.....

Not on the information you've given us. Tell us more about your setup.

1.2m dish with octo LNB

4 x HD boxes being  2 x via HDMI over cat 5  to SMART tv + 2 direct feed via RF to non SMART tv.

No signal from any of the boxes. 2 with direct feed have EPG showing so have services option . The HDMI show blank blue screen.

That would cause literally millions of Sky subscribers to lose live television, and consequently these forums would explode.  In the absence of such an event, which tends to be fairly dramatic, issues are always local to either the individual subscription address or the building fed from a communal system.

Sky+ isn't going to receive any updates (and hasn't for some time) : it's an end of life platform.

It's a bit of a mystery. I agree with you that if this was a satellite signal issue, you should still have menu access on each of the boxes. And a blue screen suggests an issue with the boxes' HDMI output. 

 

Are the boxes stacked together? I think I'd try turning them all off at the plug, and disconnecting all the HDMI outputs, except one of the directly connected TVs. Then switch that box only back on and see if it works normally. If it does, switch off and connect the other directly connected Tv and switch both boxes on etc and see at what point you get the blue screen.

I unplugged all boxes for 30 mins. I then checked the direct feed box/TV as that would eliminate the HDMI. The box shows "still initialising" and the service menu shows zero signals on either input. The other direct feed box is exactly the same.

Normally I would conclude the LNB had either got waterlogged or failed completely (lightning strike??) We did have one flash and one thunderclap the other day.

However when my "neighbour" (4 miles away) had the same problem I did not go up and start rewiring the LNB on the basis it sounded like a Sky fault.

BTW I checked the 9v feed down from the LNB and it is there.

If there is no other reason I will have to get up there and rewire with new LNB.

Sounds like the lnb or cable (if there's just one pair) to me

Re: Sudden blue screen - no signal on any cable

I have finally got up to the dish and discovered it has moved a very small amount in one of the wind gusts. I managed to move it back maybe 2-3 degrees and the signals came back 90%. I could not judge from the ground the dish had moved at all so this threw me. Having a completely blue screen problem with no EPG is because I use an HDMI over cat 5 link. So problem resolved and it was simple in the end.

Thanks for all the input. Lessons learned......
