Gilbertini 1.5m with C120 Quad LNB Triax TD110cm ,80cm,and 50cm dishes. Inverto Black Ultra and Smart Titanium LNB,s Humax HDR-1000S ,Humax PVR, Humax HD , Pace Sky Box. SilverCrest SL65 (28.2E and -5W)
My Location
Gers, S W France
A friend asked me to help, they are receiving sky news etc on the EU beam but no channels at all from the U.K. Beam. My elderly trimax meter shows 82% signal and 88% quality on sky news, but absolutely nothing on any U.K. Channels. We tried realigning the dish replacing the Lnb with a known working one but still no U.K. Beam. It apparently it did work ok until recently, do dishes themselves deteriorate ? We are in SW France, and I live relatively close and mine is ok and not noticed any deterioration of signal.

It could be any number of reasons. LNB failure, physical cable damage, water in the cable, minute misalignment, foliage growing intot he Line Of Sight of the dish, the tuner going bad on the receiver etc.....

If it was working recently (ie since the Astra 2 satellites were replaced in the last couple of years) then its a matter of working through the various possibilities one at a time.

Replaced the LNB with a known good one, can't be anything to do with Humax receiver, or cable as I receive nothing on my trimax meter no signal or picture but sky news ,pick tv etc are ok with good signals. The only thing we haven't replaced is the dish itself.

Thats probably very marginal in Gers, especially since the fec's have changed to 5/6 a while back, which needs more signal than the old 2/3.

Have a look at the map in my sig - Gers is on the borderline between 1.2m giving an acceptable signal & not receiving a signal. (The map is a few years old but its still indicative of likely dish size requirements

Since you are receiving something from around 28.2E, I speculate the dish has slipped just a tiny bit to the west.
It may now be pointing at 28.1E (or 28.2E rather than 28.35E). The BBC stuff is on 2E, which is actually at 28.5E.
If you are at 28.2E, 28.5E is more difficult to catch (the larger the dish the more pronounced this becomes.)

Taking Analoguesat's comment into account, it probably doesn't take much to upset the signal where you are.
Here in DK, reception is similar to your position:
A 1.2 will deliver, but it *must* be pointing at 28.5 for the 2E/BBC channels, 28.2E gives the HD stuff, but screws with the BBC channels.

If I am right, you should consider re-tuning the dish, and choosing between SD BBC-ITV-CH4/5 etc, and the HD stuff.
As it is only a little little bit, retuning shouldn't be a massive job. (Especially if you have a meter).

(But this is all guess-work: I will suggest retuning in any case, but you may want to exhaust other causes first)

My plan is to try my spare Triax 110 on another wall, maybe the footprint has shifted marginally We have been there for hours this afternoon, aligning skew angle etc. but not even a blip on 10803 V 22000 BBC1 SD

Trimax SM 3500 meter, 62% signal 69% quality on 10803 in the last minute at my house.

If you can't get on a 1.25, you won't get it a couple of meters away no a TD110 (which is really a 98 cm dish!).
If you spent hours, I'm sure you've tried a good deal of what people would suggest here.

But can you confirm if you tried re-aligning the dish?

Also, 10803 is H not V. But in any case, can you not try one of the other transponders with BBC1 in them (10773H or 10788V)?
You might be victim of interference at your friends house. This would explain the local-ness of the problem.
What did the spectrum look like - no bumps at all?

A typo I wrote in my notebook, but of course it is V. We tried many times to realign the dish. When we use TP 10803 22000 we cannot see a signal, when we use sky news TP 12207V we get good signal. I was told it was working OK after the satellite changes. The interference theory maybe plausible, there are overhead electricity cables nearby but they have always been there. Maybe a insulator is arcing ?anyway we will try again if only to try his single malt again

Once you get above a 1m dish then it becomes quite acute to align a dish so it wouldn't take very much movement at all to lose a signal. Have there been any strong winds since it last worked properly?

Just to eliminate the receivers try his box on your setup and vice-versa.

And when re-aligning, you had the Trimax connected directly via short (2-3m), known good cable to the LNB?
If so, then it's very puzzling if swapping the LNB for a known good one makes no difference...

You could try his receiver, on your dish, just to scan in the channels, again, and confirm that the receiver is working, also try your receiver on his dish.
Different receivers have different quality tuners, some are more capable of tuning in a lower signal quality, than others.

You might also want to try a few different transponders, on the UK beam, to check Horizontal, and Vertical polarities:

Tried another box, but irrevellent as I get no signal on EU signal on my Trimax meter.

Yes and disconnected the cable to the tv, it made about 2/3 % difference to the sky news Tp but no EU signal the New LNB was my spare black ultra quad.

It seems to me the BBC channels'reception has weakened over the las 2 weeks,
i still get bbc 1&2 on hd,but bbc4 was not watchable on hd these 2-3 past days..went fine on SD,though
Anyone noticed the same prob?
And I have lost "Yesterday" ,already for a while
This,added to a cable-to-receiver weakened connection could be a reason for your problems

Then you've ruled out a problem with the LNB, regarding Horizontal, and Vertical polarities?
You have stated that your friend gets 88% signal quality on Sky News, is this on 12207 V 27500?
What are his signal quality readings on Talking Pictures, 11538 V 22000, and Keep it Country, 11082 H 22000? Both listed on the EU beam.

That seems very low for a dish that big on a European beam transponder. How did you connect your meter to the LNB? Using a known, good patch lead? Or was some of the existing downlead used?

We tried realigning the dish replacing the Lnb with a known working one but still no U.K. Beam.
Was the known working LNB still working after it was taken away? It could have co-incidentally decided to fail just at that point!

It apparently it did work ok until recently, do dishes themselves deteriorate ? We are in SW France, and I live relatively close and mine is ok and not noticed any deterioration of signal.
Pressed steel dishes do deteriorate with rust on the reflective surface. This is normally a problem near to the sea. Other deterioration possible is distortion, say by a heavy hailstorm or vandalism. This should be obvious though. What type of dish is this 1.25m one?

When playing around with the LNBs did you make sure that the skew was correctly adjusted? Getting this wrong could have exactly the kind of effect that this setup is showing.
