I have a panny TH42PX600B Viera and it's only a year old but i have noticed that the colour gradation on the screen is pretty bad, where instead of the colours gently fading from light to dark or vice versa, they step in blocks of colour, also when watching a film etc containing a lot of dark areas or shadows, instead of it being black it shows various shades of red along with the dark areas.

Anyone any idea what is going on??????
