No satellite signal is being received

Every now and again i get the "no satellite signal is being received" message on my digibox on various channels, (not always same ones) or my picture pixelates and freezes, when I check the signal strength and quality they are at zero,
I called Sky and they took me through a trouble shooting procedure but to no avail, when I requested a visit by an engineer they told me i would be charged £65 :mad:
This mainly happens in the evening, although not all of the time, and it makes no difference what the weather conditions are, my coaxial cable has recently been renewed, My digibox is about 2 years old, I also have a spare one which is slightly older and it happens on both, my quad LNB is around 2 years old however I dont know how old the actual dish is as it was already up when I moved in.
Anyone any ideas?

That said, Dish Alignment and/or condition of LNB are the prime suspects.
It would be good practice to re-check the alignment at the time of renewing the cable - was this not done?
The main digibox is Thompson 286_534, the older one is also Thompson but dont know the model number,
It was a sky engineer that fitted the new cable and quad LNB at the same time so I presume the dish alignment would have been checked.
Thomson boxes are prone to power supply problems giving these sort of symptoms, so it's quite possible both boxes have power supply faults.
Do you have a friend or relative with a box that's known to be fully working? if so try your box on their dish, or their box on your dish to determine which is at fault.
Sadly presumption is not enough...............
It is possible you are suffering from the occasional issue that arises after fitting a quad whereby the LNB arm has been deflected downwards (due to the additional weight) a very small amount and taken weaker Transponders to the margins.
A minute upward alteration to Dish Elevation should rectify the matter, if this is the cause.
But now that you've given us the Box details, I'm more inclined to ProDave's diagnosis - or it could be a bit of both!
Signal test shows absolutely nothing for strength and quality and lock indicator is not
locked. Network ID and Transport stream both showing four zeroes.
No idea whether it's the box, lnb or dish. I can't access the dish as it's on the roof of a block of flats. And I can't seem to get to the hidden installer menu.
Oh and I can't phone Sky as I am living - ahem - beyond their jurisdiction. All help gratefully received
I had a similar problem in the analogue days and it was the LNB had a dry joint on the connector inside,I repaired it as LNB'S were expensive in those days so it's not worth it these days try a new LNB.
