Have you just spent ages setting your system up, but all you're getting is a pixelated or even no picture at all, or is your display showing a strong/high signal strength bar but a weak/low signal quality bar? Make sure you haven't overlooked some cruicial steps and requirements for good reception.
With digital reception, a weak signal will cause the picture and sound to block or disappear. You should check the following (in order of priority):
* Is the dish pointing at the right satellite? Check that under 'Services > System Setup > Signal Test' the Network ID reads 0002 (for Sky UK).1
* Is there a clear line-of-sight between your dish and the satellite? If not, you need to consider moving your dish.
* Is the dish size large enough for the satellite you are aiming at and for your location? Check that your location is within the footprint of the satellite transponder.
* Is the dish aligned correctly? A slight misalignment will cause a large reduction in signal strength.
* Is the skew angle of the LNB correct? A wrong skew angle will cause low signal quality even though the signal strength is high.
* Are the F-connectors fitted correctly? If the copper insulation touches the inner copper wire, or if the F-connector doesn't touch the outer shielding wires, strong interferences can occur which result in a reduction in signal quality.
* Is the coxial cable suitable for digital satellite reception? You should only use high-quality cables with proper insulation.
* Is the cable run too long? With cable runs of over 20 meters, some signal loss will occur. This can be compensated with a signal amplifier/booster.
* Is your digibox or LNB faulty? Try borrowing one from your neighbour's/friend's.
