Quick question,

I had a power cut the other day and when power came back on the freeview had the "No signal" message on the screen.

I have reset the box, left it unpluged looked at differnt settings on line and still no luck. I have tested the freeview at another house and it worked.

I have now ended up finding a way to change the frequency from 12483 to 12488 and that gave me the TVNZ channels.

any ideas what I can do?

Is there an option on your box to add a transponder? If so, then you need to add 12456 H 22500, and also 12483 H 22500.

Yea thats where im changing the frequency.

I have ended up using 12460 and 12486 to get all the channels.

12483 no longer gives me any signal.

thanks for your help

I had a similar problem and found that I had to edit some sort of a frequency in the satelitte part on one of my recievers every thing was on the wrong Freq. I think it was 11300 and I changed it to 10750 I think.

Hi Munkybone,

There is a possibility that your LNB was damaged in the power cut (depends what cut the power - lightning?)

It is extremely rare but I've had two cases where the Local Oscillation (11300 or 10750) has altered slightly on an LNB meaning that you have to enter a number slightly different to the standard transponder frequency to get a signal.

In your case you are getting a signal when you enter a number 3 or 4 higher than normal suggesting that the L.O. of your LNB is now 11304 or 10754.

Try another LNB and see what happens.

Cheers,  Wild Bill.
