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,

Hi, seem to be suffering a similar problem to that descibed by Terry J Russell. I'm at SG12 0XY and my freeview HD signal (CH30, 545.841 MHz) keeps dropping, causing no signal to be displayed on my TV. This happens on a Sony 32EX403, I can watch the signal quality bar drop from 100% to 0, bounce around 30 and then back to 100% when the picture comes back. The strength sits at 100% all the time. I have no issues with SD reception.

I also have Freeview HD PVR, which does not seem to be as sensitive, but I do get some breakup. Not sure if this is interference, or the TC itself.

Luke Bellamy.Ware,SG12 0XY.
Your second and last paragraph at least could be down to atmospherics/inversion effect due to the recent brief settled spell due to end very soon.
As for your first paragraph if you do receive transmissions directly from Crystal Palace itself is your aerial horizontally polarised and if so is it a group A type Yagi or group A type X-Beam aerial as such (red coloured tips).One possibility could be that BBCB (HD) multiplex generally are more prone to picture pixellations,break ups and No Signal mode than the present five remaining SD multiplexes.

This evening (29 June) after about 22.30 the signal strength on Ch 25 (10 ITV 3, 27 ITV 2 +1, 30 5*, 31 5USA, 38 Quest, 39 The Zone, 44 Channel 5 +1, 72 CITV, 16 QVC, 23 Bid TV, 60) declined and the picture became unuseable. Crystal Palace report "no problems". Is this interference from an outside source on just one channel or something else?

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
