Just bought a new Samsung UHD tv and am keen to try and tune in the above channel just out of curiosity. I have a Humax Freesat box which receives the sound but no picture (as you would expect as it's not UHD-capable) on Freesat channel 998. However, trying to do a manual tune on my Samsung tv using what I believe to be the correct parameters (see below) gives me no signal, even though I must be able to receive the channel on my rig as I get sound on 998, as previously mentioned. Even though I don't live in the UK, I have large dish and feel fairly sure this is not a reception problem.

Here's the real sting in the tail: Doing a manual tune on the Freesat box, using the parameters below, also gives no signal, even though the very same box (while in Freesat mode) happily plays the sound for that channel.

This is beyond me... I've tried switching cables around at the LNB (an Inverto quad), but no luck. Should add here that the same thing applies when I try to manually tune in 12441 on an old Foxsat, no signal there either. So that's 3 separate pieces of equipment refusing to show a signal on 12441 during manual tuning, but with one of them playing sound and seeming to be receiving the channel ok in normal mode.

Should also add that I've taken the parameters below from at least 3 different sources, sources which all show the UHD demo channel as being in the clear.

Does anyone have any idea what might be going on here... before the men in white coats come to get me?

Channel parameters as used on Samsung TV:
Freq: 12441
Symbol: 29500
Polarisation: V
(settings for FEC, QPSK etc not available)

Channel parameters as used on Humax HDR-1000S:
Freq: 12441
Symbol: 29500
Polarisation: auto
FEC: auto
DVB-S2 QPSK

Equipment
Humax HDR-1000S (Freesat box)
Samsung UE49KS8005TXXE (UHD-capable)
Humax Foxsat (Freesat box)

Sorry to hear you are unable to receive the UHD promos on Astra2. I have just checked them here on a 60cm dish and my Samsung TV UE55JU7000TXXU. Both channels are coming in well here both sound and vision. As far as I know, the parameters you give are correct. As you get the sound OK on your Freesat box the signal is there and should be strong enough when presented to your TV. Try simplifying your LNB wiring while testing. Try just using one cable between your LNB and the TV and remove all other cables from the LNB. If that doesn't work maybe the TV is faulty?

One other thought, Corrigapp. I wonder if your TV is not feeding any volts towards your LNB. You can check this with a multimeter and, if there are no volts, go to the TV's satellite menu and make sure the LNB Power is turned ON.

That the TV is 4K (UHD), does not mean that it has a 4K tuner (UHD), I have a LG40UB800 4K (UHD) that has this problem, does not have the codecs necessary to see these channels, only 1 channel of Hispasat and Wrong, in DTT2, OK.
I leave the correct parameters of the channel, they look great the new demos, very good compared to those of 1 year ago.

Que la TV sea 4K (UHD), no quiere decir que tenga un sintonizador 4K (UHD), tengo una LG40UB800 4K (UHD) que tiene este problema, no tiene los codec necesarios para poder ver estos canales, solo 1 canal de Hispasat y mal, en TDT2, OK.
Te dejo los parametros correctos del canal, se ven muy bien las nuevas demos, muy buenas comparando con las de hace 1 años.

Hi Tururu and thanks for your reply. However, I think you may be on the wrong track here. My post is not about being able to *view* the demo channels or not, it's about getting *zero signal* from their transponder, i.e. 12441 V.

I understood the problem/Entendi el problema.

New Samsung UHD TV ....... KO (no signal).
Old Humax Freesat .............. OK, signal well, only sound when not supporting 4K (UHD).
So I indicate in the other post the parameters of the channel and search the channel on the new Samsung TV, if one has a signal, it is a problem of parameters of search of the TP/Frequency or really the tuner of the TV does not allow it to tune.

In Samsung 4K (UHD), usually have a sticker indicating that they are valid for these emissions, LG now also have a sticker to certify its correct operation from the end of 2016.

Viejo Humax Freesat...............OK, señal bien, solo sonido al no soportar 4K (UHD).
Por eso indico en el otro post los parametros del canal y realizar la busqueda del canal en la nueva TV Samsung, si uno tiene señal, es problema de parametros de busqueda del TP/Frecuencia o realmente el sintonizador de la TV no lo permite sintonizar.

En Samsung 4K (UHD), normalmente tienen una pegatina indicando que son validas para estas emisiones, LG ahora tambien tienen una pegatina para certificar su correcto funcionamiento desde finales de 2016.

Only confirm that using the connection of the satellite you use on the TV is the same, if different, check with the old Humax Freesat.
If you have doubts when setting search parameters, perform a blind search of channels if you have (of course), in LG works very well.

Solo queda confirmar que usando la conexion del satelite que usas en la TV es la misma, si es distinta, verificar con el viejo Humax Freesat.
Si tienes dudas al poner parametros de busqueda, realiza una busqueda ciega de canales si tiene (claro), en LG funciona muy bien.

PS: Sorry translations.

Problem solved, it was the LNB.

I remembered that I had a spare, a quad that I bought from Lidl for next to nothing. It works fine on 12441 V and gives me all 3 of the SES UHD demo channels (even though 2 of them seem to be identical).

Reception of the main public service channels is not quite as good as with the Inverto (IDLB-QUDL40-ULTRA), but close enough.

Thanks again to all who took the time to reply. :)
