Nick: it sounds like you just have a rubbish LCD set. Mine, which is a cheap LG, has an excellent picture on the Sky channels connected via SCART. I DO have the output on the Sky box set to RGB. The analogue channels are very blurred but they go soon so haven't worried.
Despite what Brian says above, everyone I know agrees that the picture on an old CRT screen is much better defined than on an LCD : the best comparison I would make is that an SD picture on a CRT is equivalent to an HD picture on an LCD. So, yes, once again the British public have been conned into thinking that 'new' means 'improved'.

Dear Dale,
thank you so much for that. As I had only just got the lcd, I took it back to Bennetts yesterday.
If you don't mind my asking, please would you explain this rgb? This is not a setting on the tv, but on the Sky box? How do I find it on the Sky box?
Does your tv have phono sockets so you can connect a good old fashioned amp with speakers in wooden cabinets?
Those flat screens look marvellous in the shop, but when you get them home they are a bitter disappointment, awful sound and you have to sit in only one chair in the room to see the picture properly, and if you cannot get the inbuilt freeview tuner to pick something up, you have had it.
I wonder if freesat connected to my tv would have been any better than Sky.
Many thanks.

Nick: SCART can carry video in (at least) two ways - either as composite signals, or as separate Red, Green and Blue signals. Separate RGB should give a better picture. Composite (also shown as CVBS) is basically the same as a demodulated, baseband, PAL TV signal, so the colour information is still carried on a modulated subcarrier. The extra modulation and demodulation adds noise, and phase shifts can be introduced which introduce colour errors.
The RGB signals were originally intended for subtitle decoder boxes, so some old CRT TVs do overlay the RGB signals from SCART on top of whatever analogue channel is being watched. Also, they may have only some SCART sockets that support RGB input, the others only supporting composite.
You might also find support for S-Video, where brightness (luma) is on one pin, called Y, and colour on another, called C.
Check your box's manual for what the options are and how to set them. My Humax PVR-9200T defaults to doing RGB on the SCART socket labelled 'TV' and CVBS on the socket labelled 'VCR'. It can be changed to do CVBS on TV and S-Video on VCR.

Dale: I agree that for small sets or long-distance viewing, you can't tell the difference between SD and HD. However, for larger sets, if you can't tell the difference, you probably have it connected by SCART.
SCART cannot carry HD signals. You must either use component video - three phono plugs, one for brightness, one for the red difference and one for the blue difference - or a digital connection, to get actual HD display.

Thanks Mike, this is getting quite complex. If I can't find what I want in the manual, will get back to you.

Nick : the RGB setting on Sky is on System Settings, Picture.
And, no, there are no phono output sockets on my LG LCD. This was quite annoying because, as you say, the sound on many of these sets is appalling. I have had to 'waste' one of the SCART output sockets on the set by connecting a SCART to Phono adaptor into it and then connecting phone leads back into my hi-fi amp.
As I say above, I am happy with the picture on my set on all digital sources (Built-in Freeview ; Sky ; External Freeview PVR ; DVD) but the analogue picture is poor.
Mine is only a 22" : larger ones make more of HD as stated above. Smaller ones, though , seem very poor : a friend of mine bought a 19" cheapo from Tesco and it was so bad she returned it and got her money back.

Thanks Dale, picture size makes all the difference, mine was 32 ins.
There is no RGB on my picture settings, only scart on/off.
Do you know what 'second location picture format' is meant to do?
Best wishes.

Nick : on my Sky Box (non-HD) the RGB setting is under System Settings:Picture Settings:Video Output. You can set it to PAL or RGB.
The Second Location Picture Format is for watching on a 2nd set using the 2nd RF out, not if you're connected via SCART. I have a long wire running upstairs to my bedroom portable and it uses that setting to have a 4:3 picture instead of 16:9, via a Magic Eye.

Found it! Thanks Dale. It does not make any difference either way now that I am back on the crt. I must set to rgb when I have to get a flat screen I suppose. Incidentally, I thought we used PAL, or does that only apply to analogue? Your help is much appreciated.
