My new PRS700 replacement has dust spots right out of the box. Only three, one medium bright one and two dim ones, all at the bottom centre of the screen.
Again, only noticeable when reading in the dark with the sidelights on. Reading in the daylight there is no problem.
I'm disappointed, but willing to live with these few since they are in a place that isn't too distracting and since there are only three. Hopefully they won't multiply. I plan on keeping this one unless there is some kind of recall or trade-in on a newer model.
SOny really has to get some quality control going here. How much would it take to put someone in a dark room and test these out before they ship them out.
WDE.
