PW6 ghosting/smearing?

Apologies for the title, but I'm not sure what to actually call what I'm seeing...

It's most noticeable on end credits - you know...black screen, white text going up the screen. I'm seeing a horizontal "band" of grey/white (smeared from the right hand side of each line of text to the right hand side of the screen) that moves up the screen with the text. So multiple bands...one for each line. Know what I mean?

It's something I used to see often with CRTs. I figured it was something to do with the scanning they do, but surely it's a problem a plasma shouldn't get?

My other thought is that it's just interference on the signal somewhere. I'm seeing it with both PC VGA and component from a PS2. Both analogue signals obviously.

Any thoughts?

The screen will be out of warranty in a month, so if it is a problem I'd like to get it sorted soonish.

Thanks

On VGA, cinema mode, with:
contrast=-10
brightness=0
sharpness=1
white balance=normal

On component (where the effect seems more noticable with PS2 games):

Cinema again:
contrast=-5
brightness=-7
colour=10
tint=0
sharpness=3
white balance=normal

The component lead is a decent make. VGA lead is just bog standard.

Hmm, I get that on my PS2 via crappy scart on my current CRT, maybe its just the PS2

What are you doing with colour on 10?!!!

I would say that colour needs to be around -4 to -6 on the panels, andything more and smearing is exactly what happens.

That is why I prefer the JS YUV converter it means you can adjust the colour easily.

You can go into the service menu and knock down the RGB to get it looking more natural and less processed, but be careful in there.

I prefer slightly over saturated colours when playing games.

It's been like that since day 1, but it's only recently I've noticed this problem though.

I'll reduce the setting and see if it improves. Thanks for the advice.

Slightly!? :)

By upping the saturation you are causing more problems. Let us know the results mate.

Imilne,

Does the on-screen menu have any smearing on it?

Is there any way you can take a picture of the problem and post here.

I can't see how having the colour saturation set too high could cause white text to smear to the right on a black background - especially when connected via VGA or component.

I am suspicious that you do indeed have a problem with your panel.

Oh yeah, I forgot you said originally that the smearing was on white text against a black background.

What happens when you reduce the brightness?

I've tried taking some pictures, but my camera just isn't sensitive enough to pick up the effect. I guess it's not helped by the fact that you only tend to see it with stuff that is moving. The difference between what should be there and what shouldn't be there is very faint on static images.

Reducing brightness/colour etc made no difference. You can see it even on the darkest of screens.

The other place I've seen this before is with PC monitors (LCD ones too). Sometimes when moving a window around (with its contents painted), you can see smears off to the right-hand side of it.

Guess I'm just going to have to learn to live with it.

What's actually more worrying is that while fiddling around with all this I've just noticed a flickering pixel! Shows up grey on all coloured backgrounds apart from red and black. Hopefully it'll sort itself out and not die on me completely!
