as title, any sky installers here, basicly i have moved a dish which is pointing right again (im sure) but the 4 leads from the quatro lnb were disconnectd by my dim witt brickie and have been reconnected in the wrong order, anyone free tomorrow for a hr to sort and make my clients kids happy and make sky work again.
basicly we have reconnected the cables in the wrong order. it worked before we re routed the cables and they were definatly not dammaged, and system works via a switch which has also not been touched either.
beer tokens waiting but must be sorted tomorrow, anyone up for an hrs work

You can't really connect the cables in the wrong order, its more likely the dish has been moved smile

It doesn't matter which order you refit the cables...each output is independent of the other.
If you unplug or reconnect the LNB with the box power up you can damage them though.

Contrary to what the previous posters have stated, it DOES matter which order the cables are connected! You don't want someone from SKy - they won't have a clue how to fix it. Just use an independent - easy job to fix.

If you are certain that the problem is just that the cables are in the wrong order why dont you just work through the combinations? There are only 24 possibly permutations assuming that all 4 cables can go in any of the 4 slots.

itv1 and itv3 are on the two low bands if i remember correctly (marked VL and HL on most LNBs). Get those two working first and then just move the other two about untill all channels are working. Simples.

And dont worry about disconnecting everything for fear of damaging it, it will be fine

I'm sorry, but it really makes no difference which cable goes where - the four outputs are identical to each other.
Two cables will be for the Sky+ box (so you can record one channel and watch another) and the other two cables must be going to Sky multi-room boxes somewhere.
Each output is powered independently via the coax, and you should ensure all Sky boxes are switch off before playing with the cables.

on a quadro lnb all four are different actually (18v, 14v, 18v+22mhz and 14v+22mhz) if i remember that correctly and go through a switching box to each reciever and have to be balanced correctly, which is what i need doing, thanks for your help though

eta there is a diference between quadro and a quad

I had the same issue, and called Sky out.

It dosent matter which way round the cables are.

My problem was sorted by connecting everything up and then switching the box off at the mains for 2 mins, and then on again paperbag

Really, thats all I had to do. The Sky man reckons he does 5 a week....oops.

For the second time, yes it does matter. Hence why his Sky isn't working.

The cables should be colour coded or at least labelled at the LNB and the multi-switch.

Try this.

Put the Sky box on ITV1
Then on the multiswitch, find the 18v input, and try each cable from dish until this channel works.

Then put box on ITV3
Then on the multiswitch, find the 13v input (or 14v), and try each cable from dish until this channel works.

Then put box on Nick Junior
Then on the multiswitch, find the 18v+22khz input, and try each cable from dish until this channel works.

Then plug the other one into the only input left.

They might have changed the frequencies of these channels so it might not work, and even with the wrong input connected you might still get a weak signal on the channel. But might sort you out anyway.

The other thing is - are you sure it is pointed at the correct satellite? Not looking at 19E for example?

I would have hoped that whoever set up a quattro would have marked things.

Were the cable ends/LNB terminals adequately protected from the elements during the disconnection? A little bit of water in either can cause issues.
