The symbol shows the location of the Crystal Palace (Greater London, England) transmitter which serves 4,490,000 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 Crystal Palace (Greater London, England) mast?

martyh: LED illuminated LCD sets are getting to be the in thing as they allow the TV to be thinner compared to slightly older types fitted with cold cathode types, but as far as the actual picture is concerned there is virtually no noticeable difference, although I do have reservations about just how reliable LED types will be, as LED strips being used in important positions is tempting fate as its nearly always the case that one in the strip will go down.
I can forecast one thing though! being, that if you do take the plunge and purchase a new flat screen set that its almost guaranteed that you will be adjusting its picture settings every other day to try and make it appear like the CRT set, as everyone of a more critical nature I know does it, because as was mentioned in a previous reply CRT images have a lively presence attached to them that you just do not get from LCD sets irrespective of what type screen illumination method they use, otherwise though they do give very high quality images so long as they aren't priced in the lower end ranges, as pictures I have seen on some of these types can be quite appalling, and I will refrain from mentioning names.

Jb38 I suspect most people find the image on flat-panel TVs less lively because they do not have the problems inherent to CRT TVs such as slight size-change with brightness, blurred peak whites, poorly focussed corners, indifferent vertical & horizontal linearity, iffy grey-scale consistency, inaccurate & less stable colour-tracking, relatively low definition and so on. Although these are not major issues with more recent and better CRT TVs; nevertheless they still exist and can surprisingly contribute to an apparently livelier, deeper looking image until you get used to the tecnically much superior but subjectively blander image of most decent flat-screen TVs. It is a bit like preferring deeply flawed Vinyl to less flawed CDs.
It is also true that greater viewing pleasure is obtained by much larger displays with flat-screen TVs. I would suggest the largest that doesn't look overwhelming in its setting - and this is because the absence of "liney-ness" & inherent deficiencies that limit CRT TVs.
The major problem with flat screen TVs of even the highest standard/price is the impossibility of squeezing reasonable in-built sound from cabinets a couple of centimeters deep containing tiny speakers formerly found only in small portable radios and facing in any direction except towards the viewer. Sadly, this is even worse with recent LED-lit models which can be (and are) made even less deep. This can at least be resolved with "sound bars" or more physically intrusive "Home Cinema" systems.

jb38. I was really mentioning LED TV's is respect to their energy efficiency. Thanks for the extra stuff though. It's good to know my gripes are shared and it's not just me. When one considers the advances in technology, I think we have every right to expect good quality pictures, even colour balance etc, especially when one looks at the sales blurb/pitch manufacturers band about their latest TV's! Personally, I have noticed that a couple of my friends' flat TV's don't seem to give that great a picture - one looks very 'soft', or you might even say blurred - or woolly, compared to mine. ie: a bit like my computer screen if I set the sharpness to the 'soft' setting. Weirdly, setting it to 'sharp' (settings go from 1 to 5) is very hard to focus on. I hope they find a happy medium for everyone, one day.

martyh: On the angle of energy efficiency, between LED and cold cathode illumination, there is very little in it unless a person is seeking to splits hairs, as you can have two LED illumination LCD type flat screen TV's of the same screen size and both will consume different levels of power, let alone any difference between LED and CC.

Crystal Palace transmitter: no signal at all on C30 (HD channels). Tried returning yesterday and today's even adjusted the aeriel, but still no signal at all.
No mention anywhere that the Mux is down!

jb38. The energy efficiency of comparable LED lit screens is very susbstantially better than with CC illumination. When they first appeared, the quoted reliability was however worse, but has exceeded it now. However, the technology is as yet not as well refined and the LED backlight/LCD picture-element types often suffer with difficulty in achieving a true reference white colour - perhaps because LED doping/filtering technology has not has had as long as the phosphors in CC illuminators to mature. The net result is that whites on LED sets often look a slightly blueish "Persil White" rather than the correct fresh milk colour.
Most flat screen TVs are supplied with default settings which do them no favours - usually giving pictures on the gaudy side that look good in the shop. They also have a multiplicity of user settings and optimising adjustements that most users do not understand and are not competent to use. My own LG stores 161 individual picture settings for each input and within that for each resolution of signal source and then automatically applies them as appropriate. However it looked dreadful on the factory settings and this capability was miserably described in the user documentation such that few without some technical expertise and knowledge of video parameters could have successfully set the thing up to do its best. The average user has to rely on an "idiot-guide/procedure" which will achieve just passable results & is unlikely to realise that he can separately optimise it for SD, HD, DVD & BluRay etc.
Most CRT TVs were just internally set up to do the best they could with the TV signal and applied this to everything with results that often looked better - or more correctly, nicer.

Thanks jb38,FJC. I concur with everything you've said. Let's hope, that in the coming years these issues will be resolved, so jo average can get great pictures without having to fiddle around too much, or be bombarded with a plethora of settings, which most people don't know how to use let alone understand!

weare getting problems intemitantly and
Weak or no signal keeps coming. This has been happening for the las week or so and sometimes last at least 30 minutes. We had this trouble costantly before thedigital signal was switched on and we were always told it would all be ok when analogue was switched on.
can nothing be got right in this country

Re: Goodmans GDB5
I had the same problem.
I went to Signal Strength. Then using the right & left arrow keys you can toggle through the channels until you get to 28.
I left it on channel 28 for a few minutes and eventually the strength bar went green and to 100%.
I then performed a channel scan and all the channels were found.
Hope you have the same luck,
Paul.
