I had a week 12 iPad 2 and when I put it under a bright light with the screen off I can see the dots and lines of the LCD screen easily. But my 2 week 18 iPad 2s I can't. Can anyone else see these dots and lines on their LCD under a bright light? Make sure the screen is off. Original was week 18. 1st replacement was week 12. 2nd replacement was week 18.
