Re: TV buzzing when showing whites and bright colours
I had the same problem when I connected my new At&T cable to the tv card in my PC. I did a little internet research and found out that the problem is called "video buzz". It is where the video signal bleeds into the audio signal. I was connect via coax to the cable box. I was able to fix it on my system by "fine tuning" channel three (my TV card has this capablility). Your system may or may not have this feature. If you are connecting using the A/V input it may be something else.

I assume your DVD is coming up in colour when you plug it into a standard scart connector? Have you tried using a different S-Video cable because this sound symptomatic of a dodgy lead?
Check the SCART end of your lead for any bent or broken pins.
Failing that if the problem lies with the TV itself I'd really recommend having a pro look at it. Plasma's are expensive and opening it up if you don't know what you are doing is a bad idea.
It could be the tint settings on your TV. Check your TV's settings menu for color/tint options. If you can't find it, break out the manual and look in the index for tint or color, then locate the page and it'll tell you how to get there.
Make sure the tint slider is in the middle, 0 or 50%, depending on your TV.
Best of luck.

I've been looking into this myself as I've also recently purchased the KDL-40W4000. I was watching a murky old film and was getting a bit of sludgy ghosting but found that by reducing the contrast to 25, setting the backlight on low, colour on neutral and the brightness about 40-60 (and taking ALL advanced noise functions off), this reduced the ghosting considerably.
BUT, this is quite a cool and dark image. If you watch standard TV and films mainly, a variation of the Cinema setting is probably the best overall setting i.e.
colour temp: Warm 2 (although Warm 1 is less yellow and still fine)
noise reduction: off
mpeg nr: off
contrast enhancer: off
colour space: standard
it depends on what your using it for, adjust colour tones to what you think looks natural, contrast between 80-90, keep sharpness below 30. just have a play around till you find what best suits the source material.
