As per subject, full colour picture on all menus but moving pics on live tv or any other moving image have colour distortion. Have tried looking in settings but not many options to fault find.

Any ideas on what this might be?

What settings resolution do have the box output set to. Try 1080p.

Home - Settings - Picture and Sound -

Screen ratio 16:9 Display Format Auto - Resolution 1080p Audio Type Stereo. Digital Audio Out - Stereo if TV used for sound - Mutichannel if box is connected to AV receiver with Dolby Digital 5.1 speakers. The HDR-1000S normally has an excellent picture especially when tuned to a HD channel.
 
Is the OP using an HDMI connection, or some analogue link?

I don't know the specifics of the HDR-1000S, but it's hard to see where it could introduce image artefacts such as this. Far more likely there is some kind of motion processing setting for that specific input on the TV.

Is this a new problem with a system that was working OK or is a new combination that has been like this from the start?
 
Suspect this is a issue with the HDMI settings on the LG TV. The Menu overlays are 720p (1280 x 720 scaled by the output resolution settings on the box 1080p50 if set to 1080p). Some TV's have the option to display enhanced the full 256 black levels of a 8 bit source If the source uses the much smaller 12 bit Y/CB/Cr (component colour space ) this often causes issues like the OP posts. All Full HD broadcasts use the 12 bit component colour space to save bandwidth as do Blu-ray discs compressed with the H264/AVC codec. Users that really don't understand choose the enhanced option in the mistaken belief that this will give the best possible picture.

Not having the TV can only go on the options on my Panasonic TV. Selecting the enhanced version creates obvious artefacts especially on scrolling white titles on a black background as the TV tries to display black levels not available in the source data.

The colour effects you get by setting the wrong gamut are generally called "solarisation", but it's much worse if you have the TV set to "TV" and input full cinema than if you have the TV set to cinema and input a broadcast source (as would be the case here).
