Whaat?? That's terrible. Retailers should have some stock aside for exchanges of a product like this!
My replacement just arrived and is sitting boxed up on my floor. I'm going to make coffee and then I'm going to carefully open it and set it all up and compare it to the old screen.
Will post results here shortly. Wish me lukck!!
Playing my vita now and the screen seems perfect. Damn daylight making the lines go away. I do think you will have dark patches but you won't notice a small quantity of them until you play in the dark (if you ever do lol).
