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).
- 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.

Can you please help me with this problem. I just installed an h-h motor and as i live in malta i set the dish on hotbird true south. i can get almost all satellites but there are some like hispaat 30 w and the 5 e which i need and seem unreachable. if i tilt dish by hand from top or bottom i seem to get them but i lose all the others almost. could it be pole alignment but i could swear i fixed it properly. thanks regards.

Philip,
The pole must be absolutely vertical after everything is attached to it.
The dish elevation must be correct.
Your dish size should be suitable for receiving those satellites. Check www.dishpointer.com for footprints and dish sizes.
Hope this helps

What is a posible problem and solution for my satellite dish Tv has a difference in audio and video alignment. do not match for a fraction of seconds?

TG:
I guess that would be your receiver. Try doing a reset.

My postcode is UK :TS9 5AG - your website apparently sites me in Germany not UK with Dish calculations of Azimuth -34.7 and elevation 22.4.
However your google map set up finds me correctly at 157.3 Azimuth and 32.7 elevation !
Can you please advize which is correct, and where 157.3 Azimuth is on the compass compared to South.

GA Chase:
Not sure what you mean. If you point the marker at your house, it will give you the azimuth and elevation plus a line where to point your dish. South would be 180 degrees or straight down on the map.

Hi,
i am not sure if this is the way to start a new thread.
On holiday in austrian tirol, we unplugged the power to TV and Satellite top box. When powered up again it said “No Signal”. Local company insisted they needed to come round but we were unable to be there. It happened again with the kids unplugging, this time while all components switched on….it cost a lot each time for the company to re-set??? if that’s what they did.
Can anyone say whats going on here? and sureley it’s something we could have done ourselves?
thanks in advance

Something not right here. By unplugging the receiver, the card doesn’t get it regular updates so after a few hours or even days some channels won’t work (all the cheapo special interest ones will do though) and you need to leave the card in the digibox for about 24 hours to get it re-activated.
If it’s says no signal though then your dish is not aligned properly but since you’re in Tirol, are you sure you don’t get that only on the BBC and ITV channels? For these channels you need a bigger dish.
So, overall, I suggest you check the shopping channels first. If you don’t get a signal on those then you need to have your alignment checked.
