    I just bought a second refurb imac 27 and today when i received it and i started transfering the information from time machine i saw 3 little black dots on the middle of the screen, now i thought dust behind the screen? but i also consider maybe dead pixels? :confused: a scratch?

    Here are the pictures i took from the imac.

    How do i know for sure if these are dead or stuck pixels? i called apple care but it will take one week or more if i send it to check, so i wonder if there is something i can do to verify if these 3 dots are really dead pixels? or if it is dust behind the screen?

    What are these 3 points?

    Its hard to tell in the picture, but it looks like dust/debris of some sort... looks bigger than a pixel.

    RE: is this dust? dead pixels? scratch?

    It is difficult to tell from the photos, but in your image iMac06, where it's zoomed in pretty well, the black "dots" appear to be the same size as the individual white pixels of the background which leads me to believe that they are "dead" pixels.

    Now, in the "old" days of matte screens, one could lightly "rub" across the area and sometimes "unstick" the pixels and they would be fine. However, you may be able to use something like "Pixel Fix" (http://www.apple.com/downloads/dashboard/status/pixelfix.html) to hopefully unstick those pixels...if indeed they are stuck pixels and not dust under the glass.

    You can also google "mac pixel fixer" and look at other options. Let us know the results.

    EDIT: here's another option to try: http://www.jscreenfix.com/basic.php
