Richard Sutton: Yes, but have you as yet carried out the "factory default" procedure on your Humax?, this procedure always being one of the last resort as far as a viewer is concerned, as its the only way of correcting any data errors that may have occurred in the system, this action being even more effective if the mains supply to the box is switched off (rear switch?) after having carried out said procedure, "before" any attempt is made at retuning.
I did not initially mention this procedure simply because of it deleting any personal settings that you might have made on the box, whereas an auto-tune minus the aerial doesn't, likewise that had to be tried first. However as that procedure failed to make any difference to the situation, factory default "is" now the last resort.
By the way, this is also known under other names (factory reset / first time installation, etc, etc) dependant on the brand of equipment, but most Humax devices generally refer to it as "factory default", usually accessed via: Menu / Settings / Installation / Factory Default.

jb38: Surely D3&4 UHF25 carries the same services, on the same LCNs, as D3&4 UHF29. If both are scanned in, wouldn't the missing channels appear in the 800s because of LCN collision?

js: Yes, that's quite correct, and admittedly I suppose I could have suggested checking this out, but the reason for emphasising carrying out the reset procedure, is because of Richard having already scrubbed that stored in the tuner by carrying out an auto-tune minus the aerial, witnessing the result by a "no signal" warning on any attempt to select a programme channel.
If though the default procedure also fails to rectify the situation, then its time to look at other possible reasons for the problem, such as that suggested by the Freeview help desk of possible water contamination in the coax, although the symptoms experienced with that type of problem usually varies between different devices, seldom the same on more than one.

Yes. I don't know if this helps but that's exactly what happened with the Toshiba TV. When I scanned C29 it picked up only ITV exactly the same as the Sony TV and the Humax FVP-4000T but it put the new ITV on number 800. I then did the aerial unplug and rescan and a fresh manual scan and this time it put the C29 ITV into 3 as expected.
The Sony and the Humax seem to be smarter than the Toshiba and seemed to understand that the new ITV on C29 needs to replace the old ITV on C25. However, since those early experiments they've all been unplugged and rescanned as suggested by JB38. ITV is the only station on C29 that is ever picked up.
I'll do the factory reset today with the Sony and see what happens.
Many thanks for you help.

Richard Sutton: After the factory reset, carry out a manual scan of UHF29 alone and tell us what services are present. A signal strength/quality report would be useful.

Thanks for helping me with this guys.
OK, I did afactory reset on the Sony HD TV which means that after a few minutes it started by asking me for the language, then country etc. When it asked whether I wanted to do an auto tune I said no. I then did a manual tune for C29 scanning Up followed by a manual tune of C29 scanning Down. Each time is scans for a 15 seconds or so and then says "1 services found on CH 29" - ITV.
The listing at the side of this dialogue say Prog 001, 002 No Service Started. 003 CH29 ITV. Prog 004, 005 No Service Started. If I scroll down all the Progs below 005 they all say No Service Started.
When I go back to normal TV, ITV is playing "The Mummy Returns" and if I Prog + or Prog - it just flickers and goes back to ITV.
If I go into System Information it says:
Frequency 538.172 MHz
Signal Quality 100
Signal Strength 100
Pre Viterbi flashing 2.00ish to 3.50ish e-4
C/N 54
UEC 0
Post Viterbi 0
5s 0
AGC 157
I've no idea what any of that means of course!

PS I'll just leave the Sony as it is with only C29 ITV scanned in case you want me to try something else. In the meantime we can watch live TV through the Humax.
Many thanks

Richard Sutton: It seems pretty clear from that, and your first message, that ITV1 is the only service to be found on the UHF29.multiplex.
I did search for info on this, but found no indication that the multiplex is anything other than a normal D3&4. I would need a sample of the transport stream to know exactly what is happening here. This is what's so annoying about DTT - lack of access and information. On satellite, everyone sees every part of the network.

Richard Sutton : The readings taken from your Sony TV would appear to be perfectly OK, Post Verbi 0 indicating that the errors on the incoming signal have been corrected in the TV's processing circuitry.
Purely out of curiosity, as your Humax PVR is of the latest variety capable of being connected into the internet via Wi-Fi, is the coax feeding the Freeview signal into the Humax / TV positioned well away from the router or any ethernet cables connected into same?, likewise the HDMI cable connecting your Humax into the TV being well away from the coax?.
Another thing I was wondering about being, are you using a powered signal splitter?

jb38:
Thanks for the feedback on those Sony figures.
I'm using the Humax over ethernet so the wifi is not enabled. The Humax is below the Sony Smart TV and both the Humax and the TV use ethernet. The BT wifi router used for our laptops and smart-phones is not nearby. The various ethernet and coax cables are quite close but that's inevitable as, for example, the Humax is only a small box and the ethernet and coax inputs are only a couple of inches apart. However none of the cables run parallel to each other and are not cable-tied together.
The mains-powered booster / splitter in the loft space is fed by the coax which goes up to the arial on the roof which is on a very high pole. This is a bad signal area and without the booster we stuggle to get a watchable picture from any transmitter. Over the years I've tried Sutton Coldfield, Lark Stoke and Ridge Hill but settled on Ridge Hill a few years ago because the various on-line guides suggest it will be best for WR11 4HQ even though we don't have line of sight to any transmitter. I'm tempted to get Mark, the aerial man, back again to align us back to Sutton Coldfield which is a "simpler" transmitter although at 50 a time it's not something I like to do very often!
Having said all that, I don't think the cabling etc is the problem because the Toshiba Smart TV is at the other end of the house and does use the wifi but shows exactly the same issue with C29 and no problem with any of the other muxes. It is connected to the same booster in the loft so I'll have a go at removing the booster and using the straight signal down the coax which goes to the Toshiba. I'll leave the Sony and Humax disconnected in the loft to maximise the signal to the Toshiba. I don't think the picture will be very good but I will be able to see if it picks up all the C29 stations or not.
Once again, thanks for persevering with this!
Richard
