HD channel problems

[ginjaninja]

Guys need some help here before i waste money on getting a dish guy out on Saturday.

Issue started when i realised that when i was recording certain HD channels across both tuners that some would record and some would not. i checked HDD for errors and all OK.

i currently have a motorised setup on tuner A and a fixed dish on 28.2E on B.

i have now found the issue to be because when using tuner A on the motorised dish it does not tune to predominately HD channels such as BBC HD, ITV Granada HD, Channel 4 HD etc... i have found a few of the SD channels that do not work but not many.

What i can say is that the same channels when going through tuner B (Fixed Dish) all work OK.

i have a SkyBox F5 sitting around so i put the motorised dish whilst connected to VU+ solo2 and pointed it to a HD channel that does not work, i then disconnected and setup my Skybox F5 and hey presto the same HD channels work ( i even tried the other SAT cable feed to make surer i did not disconnect the wrong one. i have then tried setting the dish back up as a single non motorised dish and setup tuner B as unconfigured and still no joy

I have been running the latest blackhole image and then i have tried the latest openvix image but still no HD channels, i am at a loss and do not want to waste money when the guy turns up and he cannot get it going, as i cannot for the life of me understand why it works on one box and not the other.

could it be something interfering with the tuner or something.

any help or thoughts would be appreciated.

thank

Can you please post your signal quality readings, as different receivers have different tuners, some more sensitive than others.

Both at 0% on HD channels but 90-100 on SD

just looked at the latest catseye list after loading up and notice that FEC was 2/3 and I am sure most of the HD channels went to 3/4 a few months ago.

interesting thing is I am just running a blind scan on 28.2 and it has picked up the HD channels during the search which makes me think it has received a signal on the HD transponders as it has picked up ITV Granada HD on 11052H 23000 3/4.

50% complete so I will feedback once completed.

Thanks

Nope still no joy. No signal whatsoever.
Not even itv 2 SD itv 3 itv 4 SD are working

if your lnb on the motorised dish is a twin or quad, I'd try putting the coax cable onto another spare output.

[ginjaninja]

Single lnb I'm sad to say.

[ginjaninja]

Just tried a manual scan on 11.052H 23000 3/4 8spk and set it to network scan and it finds ITV HD and a lot more HD channels although now some of HD channels are greyed out and BBC HD is not even showing.

[ginjaninja]

Just scanned bbc hd and done a network scan found and working. However just noticed on the OSD the channel frequency is not what it should be as on lyngsat.com or king of sat.
bbc hd is showing as 10840mhz not 10847mhz, itv hd is showing as 11046mhz and not 11052.5mhz. Confused

[Mickha]

Is this scan done from the fixed dish, or the motorized dish?

[ginjaninja]

Motorised coonected setup as usals. I have totally disconnected the fixed dish

[echelon]

maybe the oscillator in the lnb has drifted ?

I would check if it works ok on the fixed dish on the correct frequency

if it does, replace the lnb on the motorised dish

[ginjaninja]

Hi echelon good to hear from you.

I was running the box with a catseye channel list with the fixed dish on tuner B and whenever that tuner was being used everything was fine but when tuner b was being used and tuner A was used to watch the current HD channel I got nothing.

Funny thing is though I disconnected the vu + and connected a skybox f5 and all channels worked fine off the the motorised dish.

thank you both for your help so far.

[Mickha]

Try disconnecting your fixed dish, from Tuner B, and connect your motorized dish, to Tuner B, and test the HD channels.
Then connect your fixed dish to Tuner A, after disconnecting Tuner B, and test that.
From memory, the Skybox F5 receivers are liked by some feed hunters, for their blind scan ability, and sensitive tuner.

You can scan in channels, when altering the frequency slightly, it was even necessary, on some channels, with identical frequencies, when using some keys.

[Mobley2]

The tuner stability on most Stb's can vary quite a bit. Some of them can show quite a variation
especially when you Blind scan, I would have thought that the VU range would be pretty stable over the frequency
range,ie 1-5mhz. People who use Biss Keys can often avail of variations in frequency, in that they can have several
channels clearing on the theoretical frequency, by altering it up or down by 3Mhz, and thus clearing several different channels.

greyed out channels usually tells me the tuner/tuners are not set correctly to an lnb...In settings check the tuners are assigned properly..

Hope this helps

right guys update this morning.

I have reloaded Catseye list 24.01.16 all sats. i have connected both tuners both set as simple, one set for single sat 28.2 (tried as tuner A) and one set as positioner tuner B.

here are my findings for when i select BBC HD England for both tuners.

Tuner A shows frequency as 10847 V 23000 2/3 clears all good, but then it gets interesting and i don't know why, if i record something on a different frequency to tie up tuner A this is what happens
Tuner B shows frequency as 10840 V and i cannot clear.

i try the same procedure for ITV Granada HD although there are 3 listed

Tuner A ITV Granada HD (1) shows frequency as 11053H 23000 3/4, Tuner A ITV Granada HD (2) shows frequency as 11053H 23000 3/4, Tuner A ITV Granada HD (3) shows frequency as 11097H 23000 3/4 all clear as expected

now when i do the same by tying up Tuner A, i get the frequency changing on ITV Granada HD (1) to 11046H and it clears but when i change channel and go back it can change to 11053 then not clear this is the same for ITV Granada CHannel (2) & (3)

puzzled to say the least.

i have in my satellite settings

motor setup set as simple and positioner
fixed setup set as simple and singel 28.2E

is this right

[Mickha]

It isn't that confusing.
When you start recording, using the fixed dish, you're limited to only channels using the same frequency, for the fixed dish, thus when you select a new channel, of a different frequency, it goes to your motorized dish, depending on your settings.
If you go into the menu, Setup, System, Customize, select Expert, and change the preferred Tuner option from Auto to B, or A, it will select this as your first choice tuner.

What you need to do is disconnect your fixed dish, from your receiver, as you know this is working, and instead check your motorized dish/LNB.
Connect this to Tuner A, go into the menu set Tuner A up as Simple, fixed, for the time being, as you have it on 28.2E, and do a manual scan, of BBC HD, then check those new channels, ensure you have the option Clear before Scan set to Yes.
Personally I would do a clean installation, of Black Hole 3.01F, without loading anything else, including any backup, or channel lists, then do a manual scan, of a few HD frequencies, on 28.2E, and check the results.

Thanks for the feedback i will try that now.

just one more thing before i do reflash the image.

i have got the box setup at present as a fixed setup using just the motorised dish.

if i reboot the box and it goes to BBC HD for example nothing clears, the frequency on the OSD displays 10847V as expected, but you leave it and nothing. However if i go into menu>system>information and click on yellow for multiplex frequency shows as 10847V, click on Blue tuner status and frequecncy shows as 10842V then after a few seconds it will clear the picture and when i press yellow and back to blue the tuner status shows 10840V. what can that mean??? just for info tried it with both tuners.

just to add something else in the pot, i have a DM800HD in the bedroom which is connected to the fixed dish (which is OK on the VU+ solo2 box downsatirs) and guess what i have similar issues as the setup downstairs on the motor dish.

thanks for helping guys i know this is long winded.

[Mickha]

Then it sounds like a problem with the motorized dish, either a faulty/failing LNB, cable/connector issues, or even a mis-aligned dish, not producing the maximum signal.
Only by testing, and checking, each component will you resolve the issue.

[ginjaninja]

thanks Mickha

I will let the dish guy come on Saturday and maybe order a new LNB for him to fit whilst he is up there, i would normally align myself but since moving in the new house i had to have it fixed on my chimney stack which i do no have ladders to access.

what is consistent the DM800HD will not receive any HD channels even on the fixed dish in the back room and the front room where the fixed dish works for the VU box.

could it also be tuner drivers with newer software although i suppose other would have the same issues.

thanks again for helping
