I call it 'rainbow screen'. Mine is not that bad, and sometimes it seems to be getting less pronounced, but it really hard to tell. I have put it out for a couple of 'tanning sessions' (in full sun) in hopes that the screen will 'cure' faster. I'll give it some more time before making a decision to exchange. As convenient as Amazon makes it to exchange, it is still a hassle, and there's no guarantee the replacement unit will be better. I just want to be reading.
So it would be better for all concerned if there's a spontaneous healing!
