Bill: AVC's "not insured for roof work" excuse seems to be widespread, as a friend of mine in the Lincolnshire area was also given the same story, with me thinking exactly the same as you when I heard about it, quite outrageous!!

Roger: Here is a few more Sharp TV codes that you could try out. 0064 0332 0554 0221 1221 0519 0880.

david c / Richard: I think that my last comment to you is very much applying with david c's problem, insomuch that any RF signal no matter of what composition can get warped by reflections or obstructions, reflections being the most likely in david c's case, or to be more accurate the lack of! as I feel that they are in evidence when the reception is good.
Analogue TV signals can vary up and down quite a bit without much being noticed on the screen, the only clue being that the picture might turn a little grainy in the evenings or whatever, however in the case of digital as soon as the signal starts to go downward and be hovering anywhere near the cut off threshold, known as the digital cliff", then pixilation and other problems start to show up, after which any further drop in signal strength will cause it to fall under the receiving threshold of the equipment in use, this varying dependant on the sensitivity etc of the TV or PVR in use, Panasonic and Humax being particularly good in this respect.
To be honest about it nothing can really be done, but it would be interesting if you david c could take a note of the signal strength before then after the picture cuts out, as even although it may have cut out the signal strength / quality indications will still be shown in the appropriate section of the tuning menu.

If this repeatedly happens it could suggest that there is possibly a fault in the memory store system in the equipment you are using, that is taking it that whatever it is automatically stores the channels shown after a scan, as some doesn't and you have to select "store".
Maybe you could mention what device you are referring to.

Peter: I found your posting interesting insomuch that in the case of my own Panasonic (G20B TV, believe same tuner) when I went into the menu to carry out a "manual mode" retune 23000 wasn't one of the options, however although not seen as a choice in the manual-tune mode this setting must have been stored within the sets auto-tune memory ( with no choices possible) as when I carried that out magically BBC HD returned.
A subsequent check in the signal strength / quality section revealed that 23000 had been entered automatically.
If you have already carried out another auto-tune and it didn't correct the problem, then it makes me wonder if Panasonics "over air" download of updates did not include your model, the operation being quite lengthy as it took approximately 40 minutes to complete on my set, with the set automatically re-booting on completion, me having taken it that the download was concerning this issue.

David: The event referred to must have been about two or three months ago now, and to be quite honest I dont really know exactly what the software update was installing, as when I arrived back at the house my wife said that it had just suddenly started about 10 minutes or so prior to me arriving, with about a further 30 minutes passing before it completed its task, the only thing I seen mentioned on the screen being the usual "do not switch off" etc before the "download complete - set will now re-boot" warning.
I didnt have time to delve any further into the details of the lengthy download, but suspect it may well have been connected with the BBC's proposed Symbol Rate changing activities, especially as this setting (23) was not evident in the manual selection list and yet it appeared during an auto-tune from the hidden "automatic detect" list.
By the way, the download took place whilst the set was running on Freeview BBC1.

John Keegan: Just out of curiosity, what is the signal / quality level showing at when checked in the tuning menu section? with the test also being carried out if the picture vanishes, as even although there isn't anything on the screen the signal / quality level will still be there, and its the difference from the previous indications I am interested in knowing.

david c: Without wishing to go on about it but just to clarify a point I was attempting to make, reception of any signals across an expanse of water can cause them to suffer from considerable levels of multipath reflections, and although in many cases this type of situation can actually be a plus point to the level of signal received, however signals received this way can also be dramatically affected by tide level variations.
RF signals can vary considerably during a 24 hour period, and as previously aforementioned not that noticeable on analogue reception, and although you report having periods of good reception the actual levels involved at the time "might" not be that terribly much above the cut off threshold, albeit what is received being of a reasonably stable nature.
The problem is that non line-of-site installations all rely up to a point on varying elements of reflections, and in your case I feel that its likely the combination of tidal effects coupled to normal minor seasonal atmospheric changes taking place that's the root cause of your problem, needless to say both being totally out of your control.

Mike Dimmick: Yes, and speaking as a long (very) term RF communications service engineer I did consider that factor, although I felt that conditions would have to really be good for that to apply at approximately 34 miles away from a 20Kw transmitter, still one never knows! as signals being received over water can sometimes have the effect as though having been boosted as well as the reverse.
By the way KA27 8AA (Arran post office) used for checking purposes, and so will possibly represent in excess of david c's actual mileage from Darvel.

John shaw: You are really referring to two different things here, but as far as the Freesat box is concerned if you have (or had) an operational Sky dish then the Freesat box will work perfectly OK with it, as indeed it will with your TV, as the Freesat box would be coupled to it using a scart connector, the existing normal aerial would not be required.
As far as Freeview on your TV goes, you don't mention where you are located so its impossible to know what kind of signal you would receive strength wise.
