I installed a freeview and box a few years ago. Really easy process it worked well. In that case I was using a basic hill box and an Engel Ku Band Universal LNB. I have since moved house.

We are now installing it at a new house, using parts purchased from the freeviewshop, but I can't get it to work.

I am in greytown. The dishes Elevation is approx 40 degrees and Azimuth is approx 318 degrees, to get an approximate fix, before making fine adjustments. I have also adjusted the LNBs skew so the wire is at the '8 oclock ' position as shown in the instructions. The dish has a clear view of the sky, as it is installed on the roofing, and surrounding houses also have dishes, pointing in the same direction and angle

The freeview reciever I have, which is a basic DTV one, identical to http://www.jbhifi.co.nz/tv-lcd-led-plasma/media-players/dtv/satelite-receiver-sku-17754/

The dish and LNB I am using are as follows

http://www.freeviewshop.co.nz/noise-11300-band-p-548.html

I don't believe there is any problem with the receiver, as it boots up fine. I do also have a signal meter, and it is able to power the signal meter. However when the signal meter is connected to the LNB and receiver, whatever adjustments I make to the dishes elevation and azimuth, the needle doesn't alter. Also using the built in signal meter on the freeview receiver, this also doesn't alter, and shows 0 zero strength and 0 signal quality. I do also have the freeview receiver LNB setting set to 11300 , to match the LNB. I have also tried all other settings. I have also tried connecting the receiver directly up to the LNB, rather than using the receiver, but the receivers signal meter still shows 0, and a blind scan picks up nothing.

Anyone have any idea what could be the problem. I suspect they have sent us a faulty LNB (DOA), but unsure how to test it. It can really only be the receiver or the LNB that could be the problem, but becuase the signal meter works (powers it) when connected to the freeview box, I doubt it is the freeview box.

I have always got my stuff off trademe, but I have not usually had a problem getting the siginal.

The only thing I can think of if it is not the LNB is that the Box has not been configured yet for the TP Frequency and the Symbol rate etc as if you don't have these correct it will so no siginal.

I take it there is power going to the LNB so the sat finder at least shows it's powered on. Can you get the sat finder to react when you put your hand in front of the LNB? Does the sat finder show anything when its sensitivity is turned to max?

If not, there is a good chance the LNB is busted.
I recently came across one where the pin that connects the LNB logic board to the LNB socket had broken off, probably due to some recent disconnecting and connecting causing the socket to rotate along a bit and twist the pin until it broke.

Hi,

In the tuning part of the menu on the receiver, you should have one tuned frequency as:

12483 MHz frequency
22500 MS/s symbol rate
22kHz off
H Polarity

and the other frequency tuned to:

12456 MHz frequency
22500 MS/s symbol rate
22kHz off
H Polarity

Do your line up while in the tuning menu selected on one of these frequencies and you should find the signal.

The other possibility is a fault with the cable (possible) or the LNB or receiver (unlikely).

Some LNB's have different polarisation than they appear. Try it turned 90 degrees to where it is now.

The best way to test that the receiver is setup right is to plug it in at another house where they have freeview running on a dish already. (make sure the LNB frequencies match though).

Hope this helps.

Thanks everyone. I managed to set it all up on a neighbours aligned dish, and found the issue was a fault with the coax connectors. Due to the angle of the wire relative to the connector, sometimes there was a connection, and sometimes there wasn't. Tuning in the box on a pre aligned satelite made it a lot easier too.
