Plasma colour purity .....

Does anyone have problems with colour purity on their plasma? I have a
Sony 42-inch (my second, the first was replaced in less than a week
because of a duff pixel) and I'm seeing a couple of 'funnies', but I
can't work-out if this is a duff panel, incorrect set-up or a 'nature of
the beast' type of thing. I'm seeing three issues:

1) The top left hand corner of the panel seems brighter to me. It's
noticeable on sky scenes in particular - that part of the sky often
appears washed out.

2) A white colour imbalance - this is only really noticeable on
b&w/white background stuff. It seems like the left-hand half of the
picture has an off-white cast, the right-hand a slightly blue cast (my
colour balance is set to 'cool').

3) Occasionally, I see a pinkish stain about midway down on the left
hand side of the screen, usually after something bright has been
displayed or sometimes during a b&w film. It reminds me of a CRT being
over-driven.

I see the problems on my $ky digibox, my Freeview box (both RGB scart)
and my DVD player (component) - it seems the least noticeable on DVD,
where I only recall seeing problem (1) so far.

My wife can't seem to see anything really amiss .....

A colleague who has an NEC panel reckons that he's seen the colour
imbalance/staining on his panel in the past via his $ky box. I've
checked-out (as best I can) a couple of identical model Sony panels in
the likes of Comet & Curry and whilst they don't seem 100% pure, they
don't seem to have the problems that I'm seeing - that said, they
weren't really showing stuff that would show the problems that I'm
seeing either.

I've heard reports that Panasonic plasmas can give an off-white white,
but nothing like what I'm seeing.

There's a vague possibility that the plasma could be picking-up mains
interference from my a/v kit, which is right next to the l/h side of the
panel. Moving it would confirm/deny this of course, but because of the
size of my living room, that's not an option.

It's possible that these issues were on the first panel that I had, but
because your eye was always being drawn to the area of the panel that
had the duff pixel, I don't recall seeing it. It's possible that my
particular choice of colour balance and screen settings could be adding
to the problem, although that shouldn't normally be the case as I see it.

As the panel is only a couple of weeks old I've spoken to my dealer
about this, who in turn is going to talk to the Sony rep. The really
galling thing is that these irritations aside, the picture is absolutely
brilliant!

Does anyone have anything similar with their kit? Are panels variable
like this? Anyone have any comments/suggestions?

TIA

Well you can rule that out because Plasmas are unaffected by electrical or
magnetic interference. Colour impurities in the panel sound more like
factory faults, I'd discuss the issues with the Dealer.

Well, according to Sony via my dealer, plasmas *ARE* affected by stray
magnetic fields! Sony stipulate that all connected equipment should be
at least 18 inches away from the unit - my DVD player & recorder are
less than 6 inches away. Now, I don't know if this a lame excuse, but
the manual does state that connected equipment should not be near the
plasma - it just doesn't say how far.

Sony use their own engineers to sort-out plasma problems and this is one
of the pre-checks that they do before going out to a customer.

Seems like I've got to move my kit, if only to prove them wrong or
right, as the case may be.

Sure - the signal may be affected but the brilliance shouldn't

Best cure - get a pukka screen. Sony use phillips glass and their own
electronics.
Panny or Pioneer - can't go wrong!
