How to change the LNB settings on a Sky decoder

Thursday, March 12th, 2009

If you have moved house to one which already has a dish, plugged everything in, but get a ‘No signal, Rainfade’ message, then there is a chance you just need to change a few settings. Alternatively, you may have a holiday house, caravan, etc where you like to take your decoder to avoid missing out on the all important TV whilst on holiday, but the LNBs are of a different type.

Please note, these instructions are not for MySky and MySky HD decoders. To change the settings on these decoders you must enter a hidden technician menu, where there is too much chance of things being upset. If you wish to take your MySky with you on holiday, we suggest you have both your dishes upgraded to an LNB with an L.O. of 10750. If it is a Sky installed dish or you are moving house to one with a different LNB, contact Sky to have this done, otherwise if you are in the Manawatu region, Legion Enterprises can upgrade it for you, or supply the LNB if you want to attempt it yourself.

The are predominantly two different LNB Local Oscillator (L.O.) frequencies in use. The two used by Sky are 11300MHz for all older single LNBs (the whitish side of the LNB that faces the dish is round), and 10750MHz for the newer dual throat LNBs (oval shaped face). If you live in an apartment, then the communal building dish will most likely be fitted with a 11300MHz LNB. More information on LNB types can be found on the LNB L.O. Settings post. The steps below will enable you to change the settings in your decoder to match your LNB.

Before you move the decoder, make sure you know your pin number! The default pin codes for older decoders is ’0000′, newer slimline silver Pace decoders default to the first four digits of your account number. If you can’t remember your pin number, you can phone Sky and have them reset it as long as the decoder is still plugged in with signal! If you don’t have signal, you will have to find a friend with an LNB using the LO settings already programmed into the decoder, or borrow the card from someone who knows theirs.

To alter a Sky decoder’s LNB settings, go into the menu system by pressing the Select button on the remote and select ‘Settings’ (far left hand option with a spanner icon), then ‘Advanced Setup’, you will then be asked for a PIN, enter it then confirm with the Select button, then select ‘LNB Setup’. Use the arrow buttons, and the ‘Select’ button (central O) to move around and confirm your selections.

Sometimes it is difficult to get to the main menu when the box finds no signal, so after powerup, wait till the box passes the ‘Wait One Moment’ and then presents the ‘Rainfade’ screen, at this point press the ‘Go Back’ button, and while the screen is black quickly press the select button. The menu should then appear.

To set your decoder for a 11300MHz LNB

LNB Power: ON
Set 22kHz Tone Use: None
Set Local Oscillator Frequency: 11300MHz KU Band
Confirm the changes

This completes setup, now use the Go Back key several times to exit the Menu system then remove the power from the decoder for 10 seconds or so and re-apply, the new LO setting should now take effect.

To set  your decoder for a 10750MHz LNB

LNB Power: ON
Set 22kHz Tone Use: Satellite / LNB switching
Set Local Oscillator Low Band Frequency: 10750MHz
Set Local Oscillator High Band Frequency: 11800MHz
Enable 22kHz Tone at Orbital Position: 156.0 East – Optus D2
Confirm the changes

This completes setup, now use the Go Back key several times to exit the Menu system then remove the power from the decoder for 10 seconds or so and re-apply, the new LO setting should now take effect.

Remember what settings your other / home LNB needs to make it easier to set back when returning home.

Legion Enterprises takes no responsibility if you can’t get it working, though if you follow the instructions correctly you will be fine.

Can I use a Sky dish to get Freeview?

Sunday, January 18th, 2009

99% of the time, the answer to this is yes, you can get the Freeview Satellite service from a Sky dish. Assuming the dish is still aligned correctly, and that the (intact) cabling goes to where you wish to have your Set-Top-Box (STB) it should be fine.

The 1% of the time when it might not work is where the dish is particularly old, and it has one of the early California Amps LNBs installed (The LNB is at the end of the arm where the cable terminates into). Many of these LNBs do not function at the polarity required by Freeview and will need to be replaced.

There are predominantly two different LNB Local Oscillator (LO) frequencies in use. The two used by Sky are 11300MHz for all older single LNBs (the whitish side of the LNB that faces the dish is round), and 10750MHz for the newer dual LNBs (oval shaped face). If you’re using a non-Freeview approved STB then you may need to change this setting in order to get it working. The Freeview approved decoders will detect this setting when first setup.
