I have recently bought an 42lg6000 lcd tv and i have noticed that on fast moving images (football, or even just a person turning around) there is a blur around the image, sometimes it looks like heat waves coming from the image. this happens on hd programs and blu ray movies but also on regular films. do you know what causes this. and what would be the best tv settings be to resolve this. Thank you for your help.

This is a problem that will pretty much just be there on this TV. I know it has an awesome picture...as long as nothing moves. You can try putting it in "Game Mode" in the user menu and that usually takes care of it but you didn't buy the 120/240 Hz tv to watch it in 60Hz. I would say exchange it, and in my opinion buy a good plasma :)
This is probably a combination of 2 things. In both causes 1 and 2 below, I would suggest checking the TV with a BluRay Player with BluRay disc connected using an HDMI Cable. If you complain about this, then the TV is probably not that great. Expect a $200 jump to a better model at the least (but this depends on what you have now). Honestly, this is fairly normal and wont change much with the next TV.
CAUSE 1: Motion BLUR
Motion blur occurs when fast moving objects are displayed on LCD TVs. Basically, it takes time for the LED lights that make up the picture to turn ON and OFF, when and object shown on the TV is moving faster than the LCD TV can turn these lights ON and OFF, you see the trail left behind as the lights dim to OFF. This look like blur because you see the current image and the trail of the old images. 120HZ and 240HZ LCD TV are supposed to improve this but honestly, they are at times 300+ dollars more and not really worth it. Very little difference except in some few cases.
CAUSE 2: Digital TV
Digital signals are hit or miss. Good or BAD. If you are watching Cable, Satelite or Antenna; it is likely you are seeing some BLOCK NOISE. This block noise is caused by missing information or Noise in the video signal. This will cause the picture to Pixilate (you see blocks and things start looking blurry too). This happens with poor signals. This also happens with the HD channels when they have more information than bandwidth (more data than that have space to send it...image shoving an elephant into a VolksWagon Beetle)
Yes, it's not uncommon. It also depends a bit on the TV. Some are better than others. There is a connection between price and quality, although it is not absolute. What kind of equipment are you using? DVD, satelite tuner etc, and how is it connected? (scart etc)
Colors can be adjusted from the menus (se your manual for reference). I've never seen a TV that don't need color adjusting before it gets good, as color experience will vary with room coloring and light, etc.
