Your post is very discouraging, apark5.
BTW, apark5, I viewed 2 50" Elite demo models in 2 different stores (had the rep play the break-in disc through it) and they were both free of "dirty screen effect."
I probably will still try to wash my 5020 myself before returning it, the sales rep told me he will try to find me another 5020 at another store and have it shipped locally, but he said they may already be gone and they will not be getting any more in after that.
Honestly, Pioneer is so full of BS. I called them and the rep said, "dirty screen effect? Never heard of that." Then when I explained it to him and told him I would try to wash the screen, he said not to bother, as the problem is likely due to uneven application of the AR filter, like he really had heard of the problem before but didn't want to admit it. He also said there is no fix to it.
The problem is, the tv is amazing, black levels and everything else IMO blows away the nearest competitor (Panasonic 800 or 850 series), it would be the perfect tv for me except they had to screw up the filter. If I had to swap out for another model, it would definately be a downgrade.
I'm waiting to see what the new Panny G10 is going to be like, if it's not much of a noticable difference I may just swap out for one of those, depending on the cost. At least Panasonic's customer service will be better.
I wonder, is there anything a bunch of us new Pioneer owners can do if we get together against Pioneer on this?
