Tuner problem....am at my wits end....

I've posted on this previously

 

https://community.bt.com/t5/YouView-Boxes/Odd-Problem-tuning-into-BBC-HD-channels/m-p/1528446#M23059

 

but the problem has now just defeated me and I dont know what to do next

 

Heres the summary:

 

I am on the Hannington Transmitter, and I have this problem with the BBC4 and BBC News HD channels (and other channels on that MUX).

 

If I tuned into one of the above channels I got a blank screen.  An error message would come saying the signal strength is too low or non existent.  I left it a moment, and the would channel appear and play perfectly.  At this point the signal stregth is around 70% and the quality 100%.

 

However, I made the mistake the other evening of doing a rescan, at which point I lost those channels completely.  They do not appear in my EPG.

 

When the problem first appeared a few months back (when I first started using this box), a BT engineer fitted an attenuator, which helped, but now it makes no difference.

 

I have done several rescans with and without the attenuator, and with different aerial cables, but no joy.  

 

When I rescan I get the option to choose between 'South' and 'Berks and North Hampshire' areas, I normally use the Berks option, but I have tried both with no success.

 

Both the TVs in the house can get these channels using their internal tuners (one is connected through the box), and my old Youview box can pick up the channels happily (I migrated to the G$ box last April).

 

This is a plea from the heart...can anyone help?   Is it worth me trying a variable attenuator?  

 

BBC4 HD is probably the channel I watch the most.

 

Help!

 

cheers

Re: Tuner problem....am at my wits end....

 

The mux in question is Com7 HD which where I live is on channe;l 31 from Winter Hil and is also at a lower power than the other mux's. The previously recommended aerial was type C/D which is optomised for channels 48-68, luckily I have a wideband aerial for channels 21-68 so don't have any problems. I set up a TV at a friends house nearby recently and could not get BBC4 HD or BBC news HD, I'm guessing this is because they have a C/D aerial.

 

Enter your postcode on Digital UK  http://www.digitaluk.co.uk/home  and tick detailed view, this will give you the channel numbers for the various mux's you will recieve.

 

This link will show the various types of aerial and the channels they best receive.  http://www.stevelarkins.freeuk.com/triax-unix52-aerial.htm



It sounds like the G4 box needs a higher signal strenth than the Tv's to succesfully tune to a particular mux.

 

It's quite possible that this is not the case for Hannington, but I hope it helps.

Re: Tuner problem....am at my wits end....

I cannot believe that an attenuator is required for COM7 specifically as UHF Channel 32 is lower power than the other channels (and could be out of aerial group for you).

 

The engineer may have fitted an attenuator to prevent problems with the higher power channels, but inadvertently be reducing your signal for COM7 too low.

 

But you say the signal is watchable on your other TVs? What signal levels do they report?

Re: Tuner problem....am at my wits end....

Thanks...yes, my other devices have no signal problems, just my G4 box.  I'll power up the old BT Youview box again tonight and check what strength it registers.  

 

Hi Colin, the reason the attenuator was fitted was because when I first started using the G4 box back in April, I had this problem.  He thought my signal was too strong (I live less than 2 miles from the transmitter).  I had no problems with other channels.

 

When I had those channels, with the attenuator, that MUX was around 65-70%.  

 

As I say, I have scanned with and without the attenuator.  Other channels are no problem, just those on Com 7...

 

I wonder if a variable attenuator could help?  I have never use done, but it is probably a chaper option than experimenting with a new aerial....

 

looking at this site:

 

https://ukfree.tv/transmitters/tv/Hannington

 

Com7 seems to be broadcast at a middling power compared to the others, but its only Com7 I have a problem with.

 

I wonder if the mods know of any other tuner probs with this model?

 

cheers

Re: Tuner problem....am at my wits end....

A quick google reveals I am not alone with this problem, and many other forums are dscussing it, such as:

 

https://community.youview.com/youview/topics/hannington-com7-problems

 

They also reveal this link

 

http://www.bbc.co.uk/faqs/loss_bbchd_channels

 

I am not sure if our box is litsed on the BBC page (is the G4 still a Humax box?).

 

It looks like a software update *may* be required.  

 

I'm not sure how to contact the mods to see if 'the powers that be' are aware or have an opinion?

 

cheers

Would the Mods have any comment on this stream?

 

I might log a ticket with BT

The G4 is a Humaxbox as far as I know. Have you tried the manual option as described by the BBC link?

If you are able a factory reset might be worth it doing to see if that will bring them back.

Re: Tuner problem....am at my wits end....

This is the trouble that the youview boxes can not  pick which channel to scan like so many freeview boxes and TV's do in that they allow the viewer to pick between auto scan or to pick a channel to scan.

 

It may be down to that box has find Internet channel too, but if customers  are having trouble in finding channels / muxes and having to call out BT staff to fix box troubles which they can only test signals by a box which scans a Mux at a time, why can't the box be made to do the same ????

Re: Tuner problem....am at my wits end....

Any thoughts on this from the Mods?  Is there any way I can get BT to help me?
