The symbol shows the location of the Rowridge (Isle Of Wight, England) transmitter which serves 620,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Rowridge (Isle Of Wight, England) mast?

Colin T: Regarding the 8K issue on that model of TV which by the way it its original fashion dates back to 2004, and although its tuner might well have been updated and factory fitted with an 8K capable chip, something which the Toshiba customer services is aware of hence the statement made by them, but whether or not this technical update had actually been activated when being set up in the factory is another matter altogether, because as you have obviously noticed yourself there are just too many people reporting this type of problem with that model for the fault to be one caused by the viewers installation.
Still, one never knows what will happen when you carry out the full factory reset, as that might trigger things into action.

Curiouser and curiouser! I swapped the Tosh 17WLT46B for a Wharfedale LCD1710AF, which appears to be a rebadged version of the same chassis, with identical on-screen graphics and all the controls in the same relative position. It tuned in a treat, and Mother-in-law is now sorted. I brought the Tosh home where we watch Hannington. On retuning, it failed to find channels 1-8, and only started on channel 9, though the Wharfedale that was there before was fine. I fear Tosh is destined for the tip!

Hi there,
I have today noticed that I have many of the BBC channels on my freeview recorder box no longer work (BBC1, BBC2, BBC News, CBBC...). The box is a Wharfedale 160DTRHDMI. It 'finds' the channels and the Programme Guide keeps it to date and accurate, however the channels stay blank with no sound or picture.
I have turned it off and on at the wall, done a first-tiem installation and even tried to search for them manually on Mux C24 as stated above but with no luck.
I have a small TV in my bedroom in in-built Freeview and that is working fine, so I guess my aerial must be getting a good enough signal.
Can anybody help me? x

Jessica: The problem you are having is most likely being caused by the Vestel T825 chassis used in the Wharfedale not having the latest software installed thereby not being able to respond to the new transmission modes being used when transmitters switch to high powered operation.
The real problem with this situation being that its no longer broadcast as an "over air" download because of these PVRs being much older models, with the only other way of getting the software being a somewhat tedious (and risky) exercise of downloading it into a PC and then the transferring it into the PVR via a cable between both, anything glitching during the process rendering the PVR totally useless.
Sometimes though and even without a software update, if when on BBC2 you flick the channel selector up to ITV then immediately down again to BB2 it sometimes triggers the receiver into operation, but its never really a satisfactory solution in the long term, as any recordings made are frequently found to suffer from skipping and jumping at random.
As a matter of interest, if it is the 2K / 8K issue (as described) that's causing the problem then you will likely find that ITV etc also vanishes from Wednesday.
The point is that you should really provide your location (pref: post code) with these type of problems so that the signal levels expected in your area can be assessed, especially where transmitters as powerful as Rowridge are involved, at least on the BBC that is until Wednesday when ITV etc also
increases its power.

Colin T: Well your latest findings could possibly back up what I mentioned about uprated IC's having been fitted but not necessarily activated by the aligners / testers at the end of the production line, this done by a direct connection onto the the appropriate PCB test points.

Hi jb38,
That doesn't sound great but thanks for your reply. My postcode is SO30.
I've tried flicking up and down to the BBC channels but no luck! x

jb38. Thanks for your interest and knowledgeable comments. It seems to me that this all comes back to the 2k/8k issue, and that perhaps on DSO2 at Rowridge I would have lost Channels 3-8 as well as 1-2 which disappeared at DSO1. This would perhaps explain why I can't get 1-8 on Hannington, which is now fully switched. Does this make sense? Is there any way of downloading new software to upgrade the Toshiba?

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.
