Blocked Tuners VU+ Duo 4k SE

[peter0026]

Hi all,

I have a VU+ duo4k SE, with two FBC tuners, a dish with two SRC LNB-s (GigaBlue Ultra SCR-LNB / 24 SCR)​

On the first 2 tuner I (Tuner A) is connected Astra 28,2° (Tuners A-H) and on the second Tuner (Tuner B) Astra 1, 19.2° (Tuners I-P)

So far everything works, I can switch between the satellites.

Problem begins when I start a recording. For example, I record a program over tuner A, than is tuner B blocked and I cant watch a program on the other satellite.

During the recording, I can watch programs only over tuner A. I can also start multiple recordings.

The same issue I have, when I start a recording over tuner B. Than I have no acess to programs on tuner A.

Settings Tuner:

Tuner A_LNB1_SCR1-SCR8 (Tuner A-H), Tuner B_LNB2_SCR1-8 (Tuner I-H)

Why is this happening? Same happens if I stream a program from Tuner A, I don´t have any more acess to tuner B. (Streaming over Android app: Dream EPG Premium)

Thank you for your help!!!

How do you have the tuners setup in the image ?

You have mentioned Tuner A and Tuner B (which is actually the tuner Slots and should just be named 1 and 2 imo).

In the tuner settings, then Tuner A - H needs to be setup for 28.2E and I-P needs to be setup for 19.2E

Sorry for the misspelling. Yes I ment the Tuner slots. I configured Tuner A-H for 28,2° and I-P for 19,2°. All Tuners have a different user band.
Tuner A-H is set to LNB1 (User Bands 1-8) and Tuner I-P is set to LNB2 (also User Bands 1-8). The settings are all the same, as in the atached pic, exept every Tuner has it´s own User Band. For Slot 1 all Tuners are connected to Tuner A, for Slot2 all Tuners are connected to Tuner I. I receive all channels from both Satellites. The Tuners are blocked only if a recording is running, or I stream a channel to an android device.

Well the only thing I can think of, is if both lnb's are the same and you definitely have used the correct connector from the lnb for unicable, rather than the legacy connectors, then instead of using userband 1-8 on both lnbs, try 9 - 16 on the 2nd lnb (tuners I-P). Maybe the receiver is getting confused somehow as both lnbs are using the same userbands.

Also I assume you have no other devices connected to the lnb's using the same userbands ?

Thank you for the tip, I will do it as you suggested. No the LNB-s are not connected to any other device, the only connection is from dish to this one receiver.

I tried as you suggested, but there is no change. When a recording is active I can´t see any chanel from the other Tunerslot.

I am out of idea's then i'm afraid.

I only have 1 unicable II lnb and I can use all 16 tuners without issue.

Can you please post an image of Tuner B settings?

 

[peter0026]

Attached the setups of the Tuner. Slot 1, all Tuners are set to LNB1 with userbands 1-8. The same for Slot 2, also LNB1 with userbands 1-8. If I set the LNB (Slot2) to LNB2, nothing changes.
Slot1, all Tuners are connected to Tuner A. Slot 2, all Tuners are connected to Tuner I.

 

[Ev0]

You have all tuners set to 28.2E with the same userbands and lnb.

Tuners A - H need to be LNB 1 with userbands 1-8, tuners I - P need to be a 19.2E, LNB 2 and then as I said above, use userbands 9 - 16 (just to avoid the box getting confused).

Only today I read this. The fact is simple: even if it is possible to manage two or more SCRs LNB by a normal switch, it is not possible to use them at the same time for recording, PiP or similar. And there is no SCR switch able to do that. You need multiple phisical (not just FBC) tuners to manage two SCRs.

Your initial picture, displaying your tuners, show 2 separate tuners, yet both are set to Astra 2, 28.2E, surely the second tuner should be set to Astra 1, 19.2E.

Can you please confirm that you have two separate LNB's, 1 for 28.2E, going to Tuner a, 2 for 19.2E, going to Tuner B, using separate cables, without any Diseqc switches, or any splitters?

Also if the picture, in your first post, is of your receiver, and not just an image, off the internet.

I have a much older VU+ Duo 2, with one double tuner, which is capable of running a motorized dish, and other dishes, from either tuner, including Diseqc switches, once the tuner settings are correctly configured.

I have two slots, Slot1, with a Tuner Module, connected to 28,5° directly to a Gigablue SCR LNB, without any switches. Slot 2, is also conncted to 19,2° to a separate Gigablue SCR LNB, also directly , without any multiswitch in between. The pictures in my first post is as my receiver is really connected.

I don´t have any switches inbetween, the LNB-s are directly conncted to the receiver. LNB1 (28,5°) is conncted to SlotA upper connector and LNB2 (19,2°) is conncted to Slot B upper connector as in the pic in my first post. Slot 1 Tuner A-H/ 28,5°. Slot 2 Tuner I-P (19,2°)

You are right, the first 4 Tuners in Slot B were also set on 28°. I changed the configuration, but nothing changed.

 

[Mick12334]

You need to start testing.

First unplug both F connectors.
Then connect the cable, from 28.2E, to Tuner A, top left, and set the tuner to Tuner A, single, Astra 2, 28.2E, and scan in channels for 28.2E. If you get no signal, try the other cable.
Next remove the cable, put it in Tuner B, bottom left, Set the Tuner settings, to Tuner B, Single, Astra 2, 28.2E, and check if it's working.
Then do the same for Tuner C, top right, Tuner C, Single, Astra 2, 28.2E.
Finally do this on Tuner D, bottom right.
If everything works, then try the other cable, and change the Satellite to Astra 1, 19.2E, do a blind scan, and see if you find any channels.

Please post back, with the results.

Sorry, I think you misunderstood me. I can receive the programms on both satellites. My problem is, when I record or stream a TV channel on one satellite (SlotA 28,5°), then I can not watch or record any channel at (SlotB 19,2°). If there is no recording running, or I do not stream (over the android app Dream EPG: https://play.google.com/store/apps/details?id=de.cyberdream.dreamepg.premium&hl=de) everything is fine, I can watch both satellites.

 

[Mick12334]

I don't see how you're watching both satellites, when your Tuner settings were both set to Astra 2, 28.2E, according to the images, you uploaded, on this site, but judging by the link, you have provided, those definitely look like Astra 1, 19.2E.

If the tuners are configured correctly, then you shouldn't have a problem, with recording 1 satellite, and viewing programs from the two other satellites.

I don't know about streaming, because if you're using a plugin, like Kodi, then you can't view the tuners, until you exit the plugin.

Why not just try one tuner, the one in slot 1, set Tuner A to Astra 2, and Tuner B, to Astra 2?

Have you tried recording Astra 1, 19.2E, then checking Astra 2, 28.2E?

 

[peter0026]

Forget the photos, I already corrected the configuration. I already tried to connect LNB1 (28,5°) to the upper connector SlotA and LNB2 (19,2°) to the lower connector. Tuner A-D 28,5° and Tuner E-H 19,2° with the same result. I dont use Kodi, it is installed but not in use. I stream over the android app "dream epg premium" on a Samsung Tablet
If I have a running recording on LNB1 I cant watch any channels on LNB2 and vice versa.

 

[Mick12334]

I still think that your problem is with your tuner setup, regarding recording, and not being able to view the other satellite.

Why not try the basics, set Tuner A, to basic, single satellite, Astra 2, 28.2E, with no virtual tuners, and Tuner B to basic, single satellite, Astra 1, 19.2E, then try recording,, and viewing another satellite.

Normally the tuners will be automatically allocated, with an older LNB, so Tuner A will be top left, Tuner B, bottom left, Tuner C, top right, Tuner D, bottom right, but I don't know how your receiver allocates the tuners, which is why I asked you to try an individual cable, in each Tuner, one at a time, and configure the tuner for Single Satellite, to get them all working.
