Hello, I have a holiday home that I visited in March and everything was working fine. But now, when I arrived yesterday, all the channels are black. I am using Fransat, and I have a PC6 card. I checked the cable, and I didn't notice anything wrong. I tried adjusting the satellite dish, but whether I move it left, right, up, or down, I lose quality, so I set it back to where it was (installed by a specialist). I think I need to change the LNB. Do you have any ideas on how to help me? Thank you. Configuration: Android / Chrome 75.0.3770.101

This is the Cahors Veox HD decoder. There is no internet.
I reset it but it can’t find any channels. I cleaned the card. I slightly adjusted the satellite dish in all directions, and each time the power and quality dropped, sometimes even to zero. The dish is at ground level and securely fixed. I cleaned everything.
Nothing works.

How are the decoder lights turned on..?

Do you have a voltage of 13 or 18 volts powering the LNB via the coax cable..?

Are the F connectors well made, no short circuit between the casing and the core..?? No oxidation, no water.

What are the values of the signal bar graphs, for the level and quality..??

Adjusting the satellite dish is nearly impossible "by guesswork"; even a single millimeter off at the bottom and you're 700 km away from the satellite. You need a device to measure the reception, precisely, next to you while moving the dish, like the SF-500 for example. https://www.satenco.com/fr/pointeur-satellite/2845-sf-500-pointeur-satellite-3700903357757.html

Is it still connected in your absence..? Of course, the LNB could also have been affected by water or lightning...

You can detach it from the dish and connect it to the end of the coax cable of your decoder, and move it by hand in front of the satellite's direction, watching the bar graphs on your decoder to see if there's any movement, you need to do this slowly... (it's very fleeting), to check if it works...

Problem solved. Change of the LNB, the old one was making white dust when I shook it, and it was misaligned by half a millimeter downwards, and the quality jumped up suddenly.
Everything is back in order.

jeannets Posted messages 28371 Registration date Status Contributor Last intervention 6 598

White dust..?? maybe salt..?? with the storm winds and there have been strong winds, carrying spray ... or else the "Korigans"

But still, it's a story that ends well..

Exactly and the question of going green.

Hello,

it also depends on the decoder you are using...

Depending on the height of the satellite dish, it might have been misaligned by the wind... bird droppings can also block the LNB..!

What receiver are you using..? is it connected to the internet..?? what does it display..??
You can try a factory reset; personally, I've encountered that several times in the same situation as you.

Also, check the card; remove it, clean it, replace it...

As for adjusting the position of the dish, I doubt you can do that with the naked eye, without an alignment device.?

Yann

The power is 90 almost all the time, while the quality fluctuates between 40 and 50 at most.
The demodulator is unplugged when we are not here.
For the coaxial cable, I have no way to measure if it is powered, but when I unplug it, power and quality drop to zero.
To adjust the satellite dish, I really move it slightly from its original position for which I made markers because it was installed by a pro. If I shift it by a few millimeters in any direction, I lose both power and quality.

Yann

I tested a few things. The device finds the Eutelsat 5WA satellite well. But no channel.
In manual search, if I cut the power to the coax, it finds nothing. If I turn it back on, I have power 90 and quality around 50 again. So the coax is powered.
If I have the LNB in hand and aim randomly, it finds nothing; if I replace it, it still finds a signal with power 90 and quality 50.

OK.. Unplugged demodulator in absence is a good point for surges and... But for lightning, it doesn't prevent it from hitting the LNB, following the cables to the ground... But well, it seems to work a bit...

Let's say that a level of 90 is a good signal level... but 50 in quality in this nice weather is not enough, with good alignment on the satellite, it should be between 77 and 88 for quality...

For me, you are misaligned, either in Azimuth, or in position and also the tilt of the LNB

see here for example https://www.toutimages.com/google_satellite/satellite.htm

For me, it's the satellite alignment that is not precise enough... and needs to be redone.
Something mysterious must have disrupted this dish... If you don't want to buy the pointer or are impatient to get a picture, you'll have to feel your way through little steps of every tenth of a millimeter, from left to right and top to bottom... until you get a better quality signal...

Don't get the wrong satellite, Fransat is at 5° West, there's another at 7° and at 4.3° which is not very far from the ground...

It would be interesting to go to "neighbors" who are also on Fransat, with your decoder under your arm and try it out at their place... it would still be a guarantee of certainties.

For confirmation, you must be in France.

Yann

Yes, I am in Brittany. I'll see if I can get a better signal, but the satellite dish is well tightened on the pole; I had to use some product to loosen the bolts.
And according to various apps, I'm pointing in the right direction.
I really want to know what happened in 3 months.

jeannets Posted messages 28371 Registration date Status Contributor Last intervention 6 598

In three months... ??? If on June 1st, a new satellite was positioned on the same orbit to do the same job... So..?? Are there any updates on this subject? I don’t know..?? That’s why I suggest testing the receiver at a neighbor’s, since it’s not connected to the internet.

I receive the same thing before and after June 1st, I haven't had any service interruptions, I haven't noticed anything, but my receiver is connected to the internet, so it may have received updates... there’s a possibility.

Yann in Brittany is almost a pleonasm.

jeannets Posted messages 28371 Registration date Status Contributor Last intervention 6 598

The Eutelsat 5° WA satellite broadcasts the channels TF1, M6, Arte, and others on

11.096 Vertical Polarization... 29950

I think that if your receiver is not set to a frequency (a transponder), it receives nothing, so you cannot see the quality bar rise suddenly when properly pointed... so you need to provide it with one.

You should be able to go into the menus, to manual search... and enter the values of the satellite that I indicated, if the transponder doesn't already exist... then initiate a SCAN which should search on that transponder only... and save... In any case, stay on this "channel" and if you get nothing, fine-tune the orientation of the dish until you see an increase in quality... and initiate the SCAN again.

Once you have a better signal, you can go back into the menus and start an automatic scan to retrieve all the channels...

That’s the idea... because I believe you are receiving nothing, so you don’t have the quality bar at 80% or nearly..

Hello everyone,
I'm butting in, try this:

Turn on the decoder, remove the card, turn off and unplug the decoder, gently rub the card's chip on a piece of clothing, turn the decoder back on, let it fully restart, reinsert the card, do a factory reset, turn it off, then unplug it for 1 to 2 minutes, then plug it back in and reinstall the decoder.
