Some channels not working on Sky Digital since I moved house

Charles Gamble

Hi all,

I live in Rep. Of Ireland and my Sky Digital setup was working fine up
until last week when I moved house.
I could previously see the RTE channels, BBC channels, etc. via Sky
Digital no problem.

However, now in the new house, the domestic channels display an error
something like "Satellite signal not available".
The normal subscription channels on Sky Digital are working fine.
The only thing that I can see is different is that the satellite and
tv aerial are coming in on the same cable. But I can't see how this
could affect it.
Also I am getting the same error when viewing Sky Box Office channels and certain music channels.
Note, I have never connected my digibox to the phone line.
Would it be possible that there is something wrong with the decoder?
Or is there something else I should do?

Thanks a lot for the help,
Charles Gamble.

Hi Charles, did you use the same dish at your new house? What make is the digibox?

I'm just guessing here, so Tony or someone else with more knowledge than me should be able to say, but does the card revert to "default" (ie UK) settings if it's not used for a certain period. Hence, it may need to be re-activated by Sky?

Your dish needs realigining at a guess, presume you are using a dish which was already installed when you moved in and you just plugged your box and card in ?

This is not possible! There must be two cables check again

Unless it has a diplexed wall plate ?

Hi,

I am using the same dish and digibox (it is a Pace model).
I do have the diplex wall plate (I think) as the sky cable and aerial cable and an FM port are all coming from the same wall plate. But I don't think this would affect it.
Do you think the dish needs realigned?
I thought it was all or nothing with digital?

Thanks again,
Charles.

Some of the channels RTE,BBC,ITV,DISNEY,THE AMP, SCUZZ,FLAUNT,SKYTRAVEL,PREFORMANCE,CHU & SKY BOX OFFICE,SKY SPORTS EXTRA are on Eurobird at 28.5 and Astra 2D,the rest are on Astra 2A & 2B

All can be recieved with the a correctly positioned minidish no problem

If you are missing the above channels it would suggest your dish is slightly out.

Check your signal level on the default transponder (which is on astra 2A) by doing the following: Services-System Setup-Signal Test. The bars on screen will tell you what level you have on Astra 2A at 28.2

Then check 2D as follows: Services- System Setup-press 01- select-Manual Tuining-enter 10.744 - H- 22.0 - 5/6 - Find Channels.

Compare the signal bars to what you achieved on Astra 2A

If you have no signal or a very low one, your dish is out.

The only two channels from that list that are on Eurobird 1 are Channel U and Performance. There may or may not be some box office channels on Eurobird but all others are on the Astra satellites at 28.2.

EDIT

Sorry, I stand corrected (not thinking straight this evening at all !!!!!)

The chans I listed are on Astra 2D & Hotbird (Beams NW Europe & S1) and if he can recieve all the other chans on Astra2 A&B then the dish could be out of line

Charles Gamble

OK.
I tried to find channels on Eurobird using 10.744 - H- 22.0 - 5/6 - Find Channels and I got a no signal error.
Does this mean the dish is slightly out of alignment?
Also, I cannot get E4 channel either.

Thanks for the great help,
Charles.

Charles see the list here .It shows which beam each channel is on, then see which ones are missing, at a guess I would say you are missing all the channels on Eurobird(NW Europe & S1 beams) and Astra 2D which means your dish is just slightly out

Charles Gamble

Thanks a lot for the help guys.
I'll get this checked in next couple of days.

And diplexed coax sharing of UHF TV and Satellite LNB *DOES* affect some channels.

It reduces the S/N overall. It is *MOST* likely to create a problem if there is strong group C/D UHF, *OR* an aerial preamp.

Not having a separate, high quality CT100 grade LNB feed from dish to box is a common source of problems.

In Ireland the 2D satellite is actually stronger than the 2A/2B, the reverse is true in East of England. But dish alignment can cause strange problems as you may get "interference" from a same transponder on say 26 deg E affecting 2D channels.

Hi,

Excuse my ignorance, I'm not sure what you mean by "strong group C/D UHF, *OR* an aerial preamp".
The aerial is in the attic and I have a booster that is plugged in also in the attic.

List a few channels that are missing. I was missing a few (ITV, Euronews and others), searched google and came up with this page:

http://www.satcure.co.uk/digirep.htm

Go down to the "Some Channels Missing" section. Basically the digibox sends signals and power up to the LNB, and if the cable between them is poor, the LNB may not function correctly.

Refitting the f-type connectors to the cables, then rebooting the box sorted the problem.

Aerial TV channels in the 60s are Group "D". These are too close to frequencies on cable from dish (LNB converts 10.5GHz to 12.7 GHz satellite to 750MHz to 2100MHz for the coax cable to the Digibox).

Booster = "aerial preamp" These are nortorious for causing problems unless a superior quality properly installed with correct gain, a major cause of Mobile radio creating TV interference as well as TV aerial signals creating interference (harmonics) on a shared satellite coax cable.

Disconnect the TV aerial stuff and "booster" and its Power unit and loft aerial connection etc at both ends / wall plate so ONLY satelite box using the cable and see does that make a difference.
