The symbol shows the location of the Sudbury (Suffolk, England) transmitter which serves 440,000 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 Sudbury (Suffolk, England) mast?

nick: If you do not see any choices being offered on the TV then you are likely to be using composite video, but on the subject of the potentiometer, pin 17 is the common ground and so it should be connected to one side of the potentiometer and with scart pin 19 (comp out) being connected onto the other end, the wire that was "originally" connected to pin19 and which goes into the TV being connected into the potentiometers middle tag, this then enabling the comp output to the TV to sweep from zero signal to full strength.

thanks JB. This should reduce the sound buzz AND the picture 'overload?'

nick: Yes, it should do, but with the proviso being that you have verified the problem is not being caused by a faulty connection on any of scart pin numbers 4 / 17 /18 / or 21 all of being grounding pins, because all you are effectively doing is reducing the video drive level being fed into the TV's comp video input.
But please note the following, that said concerning the mod refers to the scart plug that's connected into the box and not the TV (different pin numbers) as its easier to observe what's happening on the screen this way, but what to do first of all is remove the casing from the scart connector and for ease of identification mark the wires (using Tippex or similar) connected to pin 19 and also 16 then plug the connector back into the box.
Next, switch the TV and box on and select any channel whose picture content results in an element of buzz being heard then carry out the following test, carefully snip the wire where it joins pin 19's tag which should result in the picture vanishing as well as the buzz on the audio, albeit that the audio content of the channel the box is sitting on will still be heard, however if the picture did not vanish when you snipped 19 then the TV must be using its RGB input, and if the input mode is not selectable via the TV's set up menu then the way to force it to switch to comp is by snipping the wire on pin 16, you could check this before doing so by temporarily shorting pin 16 onto one of the ground pins, the only problem there being that you "might" have to switch the TV to standby then back on again "whilst holding the short in place" before it will switch.
The final point being, that although I mentioned using a 1k pot this is because that any enthusiast in this field is more likely to have this (or a higher) value kicking around, whereas a much lower value of say about 200 ohms (or slightly less) would be better by it give a more even sweep across the adjustment range as you are only dealing with a low impedance circuit, the effect of a pot being too high a value being that it acts more like an on / off switch rather than a variable.

nick: Re: subject of the potentiometer, if you are acquaint with soldering on smaller items then you could use a skeleton preset of the smaller variety and solder its two fixed tags directly across pins 17 & 19 on the scart plug, the wire previously removed from 19 being soldered onto the presets variable tag, this making a really neat job of it.
The advantage with skeleton presets being that they can easily be obtained in a range of lower values plus of course they are really cheap!

thanks JB, I have several second hand ones, don't know what you call them, about 1cm square.

BBC Red Button HD (303) seems to have disappeared from the EPG. Is this related to the introduction of the new BBC HD channels?

CBBC HD and BBC Three HD currently show up on the EPG. Do you know if the others (BBC Four and News) will be also be available from the 10th Dec, or are they not for this region?
