You can check the strength of your signal using your Sky remote control:
Press Services, 0,0,4, select.The grey bars displayed will show you the strength of the signal to your Sky+HD box.
If you do not have any signal strength or quality, switch the Sky+HD box and TV to standby, leave for a couple of minutes, then switch any connected items off and unplug from the mains.
Disconnect and then reconnect the cables coming from your satellite to Dish Input 1 and Dish Input 2 (brown sockets) at the back of your box. These are screw connectors; turn clockwise to tighten and anti-clockwise to loosen. Do not bend the copper wire in the middle of the satellite cable and ensure you screw the connection onto the back of the box until it is secured tightly.
Plug in and switch all products on again and confirm that the signal test screen shows the correct results by following the instructions in steps 1-4 again.

This won’t affect your saved settings and recorded programmes, but will interrupt any recordings currently in progress.
Before touching any cables, press the standby button on your Sky remote, and switch off your Sky box and any devices connected to it (TV set, DVD player, games console) at the mains Check that the power light on the front of your Sky box has gone out before proceeding.
Gently unscrew the Dish Input cables connecting your Sky box to the dish. Check the cable hasn’t come away from the metal housing and that the central nozzle isn’t bent or snapped. If the cables are damaged, call your engineer or contact us and we will recommend one.
The cable has 2 parts which must never connect. The core and the braiding, which is like a copper(sometimes aluminium) sheath. Make sure none of the braiding is touching the core. Even 1 whisker of braiding touching the core will cause you to have no signal.
If the cables look okay, carefully push them back into their sockets and screw the connectors on. Don’t use a spanner, finger-tight is sufficient.
Check also for sharp bends in the cable, that it’s not trapped (under furniture, for example) and there’s no damage to the plastic sleeve.
If after checking all of the above and you still have no signal try to locate a friend or neighbour who has Sky and temporarily swap boxes. If your box works with their dish then it’s likely you have a problem with your dish or cable and you will require an engineer. If your box doesn’t work with their dish and theirs works with your dish then it is likely that your box is faulty.
