Colin T: Well if the problem is purely connected to the issue of 8K operation then you shouldn't by rights be able to get anything at all from Hannington, but I have had instances in the past where a device fitted with a so called upgraded tuner behaved erratically by intermittently failing some 8k channels but never on 2k ones for no apparent reason, this giving rise to the suspicion that the problem was that of a two fold one insomuch still that of the 8K issue but coupled to a possible intermittent fault in the tuners PLL oscillator circuit, tuners never really being repaired because of their critical nature and as such are just replaced as a complete unit, tuner replacement is only a 15 / 20 minute job anyway.
However it this particular case it was strongly suspected by more than myself that the problem had most likely been caused by a bug in the newly developed software used at the time by the manufacturer and something very few will ever admit to, at least openly anyway!
With regards to your software download query, I really don't think there is anything you can do about this as Toshiba would be almost certain to say that it doesn't require it, and although these devices are well out of any period of warranty its almost guaranteed that if they weren't, and Toshiba had one returned for that problem, then the first thing they would do is to either replace the tuner or even the complete set, as a number of these imported devices are always held by service depots purely for the purpose of being used as a replacement, this done rather than stocking a multitude of spares.

We live at Holton Heath and have previously had decent reception from Rowridge. Since switchover, the new mux on C24 has been okay, but since yesterday afternoon we have had intermittent poor/no reception on this mux (others are fine). Is this something to do with the switchover process?
The signal power is at a constant 76%, but the quality is single digit - yet yesterday evening it was much higher.

...Thinking about it, could it be co-channel interference from France?

The whole of MUX-C has gone walkabout again. Everything else is fine but C is non existent and has been all day.

Solent Viewer.I would look up inversion effect.Also there is a possibility as you mentioned that Rowridge's Mux C on channel 37 may have been temporarily swamped by the analogue Channel 5 signal from Crystal Palace.It is a possibility !

Solent Viewer.What i forgot to add is that the analogue Channel 5 signal from Crystal Palace uses channel 37 as well !

jb38 I think you are right about not getting Hannington on the old Tosh. Here in Winchester we can get both Rowridge and Hannington, and looking at the signal strength I think I was probably getting Rowridge (after DSO1 but before DSO2)from the back of the aerial pointing at Hannington, rather than anything from Hannington post DSO2. Anyway, the Tosh is now definitely for the tip, and many thanks for your knowledgeable and timely advice

Solent-Viewer I think Roweridge has been having intermittent problems since Monday (the 12th.)
On that Monday afternoon (14:00hrs) I was watching a film on 4+1 and after about twenty minutes started getting pixelation and the 'no signal' warning problems forever appearing. I thought it was just that channel but after about five minutes I flicked through every station and found everything was screwed up in a similar way (and the only channel I could get was Film 4.) I had to give up watching but left my set on and checked it from time to time and at around 17:00hrs everything was back to normal.
Now weather would not have affected every channel with interference as I experienced it and my belief is something is wrong with the transmitter and they try to fix it outside of peak time viewing which is why you could well be having some reception problems.
I may be wrong..and if I am good..but my feeling is all will be sorted out come the next retune on the 21st..we'll see.
Just thought I'd mention my experience in view of your troubles.

Colin T: Thanks for your update, as I am always extremely interested to know the outcome of situations such as yours, and with this irrespective of whether or not it might confirm my suspicions about the cause of a problem.
Its a bit unfortunate about your Toshiba as its one of the brands I rather approve of, but it would still make a good monitor if used with a cheap Freeview box coupled into it via a scart lead, or alternatively it being used on its analogue setting to view a Sky boxes RF modulators output.
Anyway, much obliged for your update.
Regards / jb.
