Hi there Vincent,
Just finished reading your excellent (as always) Pioneer 5090 review. I've had the set myself for about 5 weeks and while I'm really happy with it, I recently discovered what has been bugging me since I got it - the dreaded dirty screen...
I was just wondering if when you say in the cons section:
"Subtle uneven blotches/ streaks on screen (mostly invisible during normal viewing)"
Is this what people normally refer to as 'dirty screen'? It was good to see you have put this as I think it's what I've been seeing.
The only thing is I'm not finding it that subtle although I think I may just be very aware of it now.. It's very clear when playing GTA 4 on the PS3 and I move the view across the sky for instance. Also easy to see on DTV via my HTPC. On lower quality sources like Sky via RGB Scart I see it all the time.
It's like looking through a windscreen with dirt on it.
I was just wondering if you would be willing to carry out a little test for me if you still have the 5090?
It's a test using the PS3 picture viewer in 200% zoom mode while panning over a photo with a skyline shown. This shows the problem very clearly on my set and it looks quite pronouced (like the image is being scrolled beind a mesh or filter on the screen which has dirty black patches on it and some faint vertical black lines and certain intervals).

I know it's asking a lot for you to take the time to try this but I would *really* appreciate hearing what you make of the effect you see, as I massively respect your skill and knowledge in this area.
I am basically trying to work out how bad my set is in regards to the dirty screen to determine whether it's worth getting a replacement. If you don't see much of an effect when trying the above test I may have reason to do this..
Massive thanks in advance if you can do this for me but I totally understand if you don't have the time or if the 5090 has gone back now.
Thanks again for a top review - you really do offer a superb resource and service to the community... Especially to us overly 'enthusiastic' users..
