Newbie to Octagon

[laserquest]

Hi

I've just returned to the forums, and having had a VU+Duo which has never been the same since the capacitor issue, I've just ordered an Octagon SF4008 which I'm very excited about. Any tips gratefully received.

Nice receiver, you find that its like a Ferrari compared to your old Duo.

Having a problem with the tuner on my new box. I’m using Vix and can’t pick up any freesat signals from my fixed dish at 28.2e. In fact I can’t pick up any signals at all.
Am I missing something obvious?

It's more like a Robin Reliant at the moment. Can't receive a thing on it! Tried connecting the freesat dish to both connectors and neither are showing a signal.

Could I possibly have got one with a dead tuner? Or could there be a software reason for it? Have checked connectors, patch leads etc.

Are you sure the dish is lined up correctly and that it is in working order? Its doubtful that you have received a receiver with 2 dead tuners.

Another thing it could be is if your dish has been setup for use on Sky Q as they use a different type of lnb to most satellite receivers.

How have you set the tuners up? I assume you have set them both up for a single dish on 28.2e

Hi also which version of octagon 4008 did you buy, some come with different tuners, i think, so if you ordered one that does cable TV only, you wont get any sat signal.

Not saying this has happened, just a thought

Thanks everyone for your input - I really appreciate it.

I've got a standard Sky dish with an ordinary twin LNB - I took the Sky Q LNB off. The dish works fine with the Freesat tv I have, and even receives with my old VUduo box - just not with the Octagon.
The twin tuners are both DVB-S2 on the same double module - it's this model: https://www.world-of-satellite.co.uk/satellite-and-terrestrial/digital-receivers/4k-uhd-digital-receivers/octagon-sf4008-2xdvb-s-s2-s2x.

I set the Tuners up (Vix image) with Tuner A Simple 28.2e, and then when that didn't work, tried the same with Tuner B.

The aim is to have the same setup as I did with my Vu+Duo - Tuner A - motorised dish, Tuner B, Freesat. I haven't got the motorised dish mounted yet so I'm just trying to use this time to establish that I have a working box.


I suppose my options are - a) try flashing a different image onto the box such as ATV, or b) send for a replacement.

You could also just open up the box (5 screws?) and take the tuner out and then reseat it.
I would not expect you will see any difference between ViX and ATV for the SF4008, they both work (I used to have the SF4008)
If it works with the Vu+, I assume you are using the same cables to the SF4008?

Hi folks. Many thanks for your further help and suggestions. I've now managed after 4 reboots to get a picture on Tuner A and B, but with no sound!! Also, while picture is perfect and unbroken and the signal is 93-99%, I'm getting weird AGC readings - e.g, ITV HD SNR 99% AGC 24%, or ITV4+1 - SNR 99%, AGC 0%. Is this a software fault?

I've read there have been issues with recent Vix images and no sound, but what I can't find is a way to solve the problem. I've tried toggling the audio tracks and going into the Audio settings menu. I know it's not the HDMI lead into the TV because it was working fine with the VUduo. Any suggestions?

The recent sound problems are only related to cable reception
Have you selected the mute button on the remote?

:-) Yes I've checked volume and mute settings on both box and TV too! I've also checked the settings on the Samsung tv - there's an option to switch between PCM and Bitstream sound, and I tried toggling that also. No joy. If anyone can think of a setting on the box that might be preventing audio from playing, or has any comment on the unusual AGC readings, I'd be delighted to hear from you.

[twol]

AGC is not relevant, and the SNR depends on the drivers, so is a relative thing.
Main menu/setup/audio & video/setiings
-> AC3 & DTS downmix set to Yes or No? ... depending on your connection to the TV or through an amp, you might need to change the config,

[laserquest]

Thanks for the clarity re: AGC.
On the Audio front, yes I've toggled those settings, and have just tried them again - no joy. The ACS and DTS Downmixes are both set to 'yes'. My set up is very simple - HDMI 2.0 direct into brand new Samsung 4k TV.

[twol]

Are you using the cable that came with the receiver?
When I had the SF4008, I tried through amps and direct to a 4K monitor (with sound) without issues.
Regardless I would probably try a different hdmi cable..... or send the Samsung back:):):)

[laserquest]

Have tried other HDMI cables (I had 4 installed through the wall for future proofing)
Have rebooted TV and Box, adjusted settings on both.
What I do notice is that when pressing the audio button, there's an x next to the Audio channel, no matter what channel I select. I can't recall if this is normal or not as I hadn't used my VuDuo in ages.

I think the only solution is to flash to the previous version of ViX to see if that solves it.

[laserquest]

Fixed it! It was a driver issue. I reverted to the last version of Vix for Octagon that doesn't have certain new drivers, which apparently have caused problems. I've reverted to Vix 5.0.26 and I get full sound.

Thanks to everyone for all their help! No doubt I shall be back when it's time to learn about Oscam. ;-)
