HD channels missing after retune on 31July2019

bobthegas — Sun, 11 Aug 2019 15:39:51 GMT

Both BBC NewsHD and BBC4 HD are missing after a recent retune on 31 July 2019.

How do I re over them?

Those channels are carried on multiplexes COM 7 and COM 8 respectively.

Using this list, can you please look and see if you have lost any or all of the channels also carried on these two muxes?

Can you please also put your postcode and house number into this link, select detailed view, and see which transmitter you are probably using, and if it, or an alternative transmitter you might be able to use, carries these muxes?

And let us know what you find....

The digital clearances have robbed some viewers of COM 7 and COM 8 on their current transmitter, so it may be a case of switching to an alternate transmitter, by aerial realignment or replacement, if this is indeed at all possible where you are.

I am not receiving any of the channels listed under Com7 & Com8. I receive signal from Caldbeck transmitter. There are no other suitable Tx that carry Com7&8.

Who do I complain to re loss of service?

Hi @bobthegas

Looking at your Signal Diagnostics (Remote HELP, Signal diagnostics normally at the bottom under Troubleshooting and system information. What is your Signal quality and Signal level.

For example I am only 8 miles from the transmitter and mine is.

Signal quality: 100

Signal level: 94

Both are 100%. I can see the lights on Caldbeck Tx at night.

@bobthegas

According to this page, (and touch/click Caldbeck there for the details) there was a retune event for Caldbeck on 31st July, but no loss of muxes, and no actual change except to the channel carrying the BBC B HD mux.

Try another retune.

If still no go, try forcing a complete retune by disconnecting your aerial and then tuning, which will clear everything. Then plug the aerial back in, and tune again, see if you get everything back.

If you do, fine, though it would indicate these sets have a faulty retuning algorithm.

If still no go, then I suggest you contact a local aerial fitter and seek advice; they should know if something is not right up there at the Caldbeck transmitter, or if your aerial setup is no longer optimum, and they can fix that for you.

The people you complain to, if necessary, are Ofcom, but they will likely want you to have done all of the above first.

I returned with aerial disconnected, powered off a TV, repowered it and all the original channels were still available! I then retuned again to no effect as all Mux Com 7&8 channels still missing.

So we are saying that the set’s response to being tuned with no aerial in is to preserve the existing tunings?

Logical, but only if the channel following logic in a dynamic retune is perfect, which I have seen it not be on Sony digital tuning.

Could you bear to Factory Reset it? That would certainly force a complete retune.

It might also be worth asking any near neighbours with HD TVs if they have lost these muxes/channels or not.

Yes existing tuning was preserved.

I was at friends last night who lives a little closer to the Caldbeck transmitter but to the west. He had not retuned his Sony TV recently(not Android). After retuning his TV he too had lost all the stations on Com 7 & 8.

I will try a factory reset later today.

Hi @bobthegas

If I am understanding you correctly. Your friend has the same problem using the same transmitter so this points to a problem with the transmitter. Performing a TV Factory Reset is unlikely to help.

Or possibly it points to a problem with Sony TVs.

It sounds from the above that his friend’s TV was fine, still pulling in COM 7 and COM 8 even after the 31 July event, until he retuned it, when the set no longer detected these unchanged muxes on their unchanged channels.

At the risk of spoiling all his neighbours’ reception, @bobthegas needs to find somebody with a Samsung or other make of HD TV, and see how this behaves.

The thing I’m slightly wondering is if these TVs have locked on to a relay rather than the main transmitter.

Bob, can you check and see if you have:-

21	5 USA	Entertainment	SDN
22	Ideal World	Entertainment	ARQ B
23	Create & Craft	Entertainment	ARQ A

as these are channels that the main transmitter should have, but relay transmitters won’t.

Best now I think to talk to a local aerial fitter, as these are likely to know what is going on here.

My friends Sony TV was showing BBC News HD in the guide before he retuned, but on selecting the station there was no signal.

i have checked a neighbours Samsung TV. And he is missing all those channels on Com 7&8.

I rang the local Sony shop this morning and they confirm that the loss of channels is universal in the Cumbrian area using Caldbeck.

i am receiving channels 21,22 and 23 OK

Hi @bobthegas

Here’s the bad news:-

https://www.freeview.co.uk/tvchanges/caldbeck

So Digital UK had it wrong, and those muxes are gone 😰

Edit: I’ve let them know, but it seems to have been fixed now, and those two muxes are no longer shown.

The good news, if good news there be, is that it is not a Sony TV problem.

I think a complaint to Ofcom may be merited, but I don’t know how far you will get.
