Sounds like it has the 'Split NIT' problem, basically not enough allocated memory to order the channels in the correct positions. In 2008 the NIT table was split, because the total amount of channels on Freeview forced the situation.

A number of receivers from the early 00s suffer from this problem, there might be an upgrade available from the manufacturer, but it's most unlikely. Even early Sony models affected, have no available fix

Chrisjnr, thanks for that. I didn't look for a "delete all channels" option but simply did a factory reset on the TV before the scan. I'll try removing the TVonics box and seeing if that makes any difference.

Mark C, your point about the Split NIT problem sounds like it might be the cause but the TV is a bit later than the early 00s, having been bought in 2006.

Do you also have a Q321? I don't recall anything being tickable: I just selected IDTV as the source then carried out the autoscan.

The TVonics box found 73 TV channels and 24 radio channels which it dutifully put into the usual order, with BBC1 BBC2 ITV1 Ch4 and Five heading the list. I didn't check the signal strengths. My impression was that the TVonics' picture quality was better than the TV's.

So there was nothing fundamentally wrong and it's a happy ending for my relative. Thanks to everyone who contributed thoughts and ideas.

My TVOnics DTR HV250 finds 115 channels in all

TV Channes: 75 (those two different from your count might well be the two Sky Sports Channels?)
Radio Channels: 24
Data Channels: 16

What's on each mux?
See here. for the lists of what channels are where.

Is you relative using HDMI or SCART to connect the TVOnics to the Hyundai, by the way?

I did notice that there was no detection of BBC3 and BBC4 - possibly because they weren't transmitting at the time I did the scan?

After posting my previous reply I also discovered a (well hidden) method of rearranging the channels on the TV, so at least things are a tad more logical now.

They should still be detected, on LCN 7 and 9, even when they are not broadcasting.

Ah. I'm pretty sure they weren't, at least by the TV.

no i have a LG TV not Hyundai ,,

[freeviewhd]

I live on the Romney Marsh. Since switch over I now get French HD channels as well through my standard Freeview box but the UK Freeview box channel signal is irratic. One minute they are high, then low, then no signal, 10 mins later high signal again, the whole things rubbish, the service is worse now. I have a brand new tv, a 2 yr old large aerial on my roof, all new cabling and up to yesterday had every freeview channel full strength. Now, since the so called Boost, its worse... but I can now get channels from Europe, how can that be, the UK signal is boosted but channels are lost but I can now get French channels, something is WRONG

You may be tuned in to Margate, Heathfield or Blueberry Hill instead of Dover or as weel as Dover and the better signals may be further down your channel list.

The 5 UHF frequencies for Dover are 50, 51, 55, 59 and 48. Hopefully there is a signal detection menu on your STB which will give you the UHF number for the current channel you are attempting to watch. It should match one of those 5.
(Details of the UHF frequency numbers can be found at http://www.digitaluk.co.uk/postcodec...29+0SE/NA/0/NA. On the link you will need to page down a bit to see them.)

By signal being high or low are you referring to the STB's signal meters? If you are referring to the quality meter another possibility is that your aerial system is too good and it is overpowering the STB's tuner. If that is the case then if your STB has a signal strength meter then that will be showing 100%. When a tuner is swamped by the strength STB's don’t go any higher than 100%!
But if are referring to the signal strength meter then obviously that is not your current issue.

If you have some sort of signal booster or amplifier either inside the house or on your aerial mast then that may not be helping. If you have it could be the cause of picking up too many confusing signals and it also can be a cause of tuner overload for signals that do not need a helping hand.

As Luis says, the problem is likely to be the tuner overloading due to the much stronger freeview signals since DSO.
If you can, remove the preamp from the system. There's no need for all that gain now.

To the OP

Does the Hyundai come with a manual tune option once you've done a retune without any aerial or booster?

If you put your relative's postcode and house name or number into www.digitaluk.co.uk and tick the detailed view option, it will say which transmitters serve the property.

For the sake of an example, The Ship Inn in New Romney according to DUK gets DTV Dover on 50, 51, 55, 59 and 48 for SD and 53 for HD (though I think the landlord/lady uses D-SAT!

Yes, it does but I haven't looked at it yet.

...once you've done a retune without any aerial or booster?

Ah, you've lost me there. I can understand doing a retune without any booster (though in fact my relative doesn't have one as far as I know) but how would it be possible without an aerial?

If you put your relative's postcode and house name or number into www.digitaluk.co.uk and tick the detailed view option, it will say which transmitters serve the property.

Thanks for that: the principal one seems to be Dover. I'm not clear yet on how the detailed information relates to carrying out a manual search, though; I'll investigate further.

Well, it's to clear the memory, to be honest.

Sorry to be a cause of confusion

On the TVonics, if you bring up Manual Tune on BBC One, it will hepfully say 50 so you'lll know you need a manual tune on the Hyundai to Dover as the TVonics does go for the strongest signals.

Signing off from this thread:all the best

Bert

The numbers in grey under the N column header are the UHF channel numbers for each mux. In manual tuning mode you enter each of these numbers in turn into the appropriate section of the screen.

The TV/STB then goes directly to that channel and just loads whatever programme services it finds. You repeat for each of the muxes.

By the way if you do not have a Freeview HD receiver don't bother with the BBC B HD mux as your TV/STB will never tune into it unless it is a Freeview HD set (which is not the same as being Full HD or HD Ready by the way)

[albertd]

The UHF Channel Numbers which should be needed for a manual tune on Dover are:

50
51
55
59
48

Plus 53 if you have HD.

These should be the numbers on the Digital UK checker result, referred to in Post #40 by chrisjr and also mentioned in Posts #35 and 37

[Bert Coules]

I just did a manual search on channels 50, 51, 55, 59 and 48.

Still no BBC3 and BBC4!

But it has just occured to me that I didn't delete the results of the previous autoscan first. Perhaps that might have made a difference.

They ought to be there - But wait until after 18 58 tonight and they may appear!
