Our sky was doing that I rang them hundreds of times and have had 4 engineers out
1st time they changed the lmb (knob on dish) no good they went away it was working a few hours later it wasnt,
they came again and changed the box they left it was working a few hours later it wasnt
they came again and changed the box again and matched the card with the box...guess what ....you got it
they came again and this time put up a new dish and checked the box,so far so good and that was a few weeks ago.
We turned the box off at the wall and waited 2 mins then put the plug in got the lights on the front but didnt turn sky on for a few mins..that helps.
I couldnt really complain about sky as the set up was a few years old,they were going to charge me 65 pound to come out and fix/replace what ever was wrong...I had a moan and said I would cancel sky and guess what..................they did the lot for FREE.
