How to remove display glass from iMac Pro?

[chaunce322]

I have an iMac Pro I was getting ready to sell when I noticed, what appeared to be, some dust behind the display glass, on top of the display.

I checked ifixit's website, and saw the display removal process to be within my skillset, so I purchased the replacement adhesive strips and got to work removing the display.

I was able to remove the display without issue, but it would appear the display glass is somehow affixed to the display itself, so there's no way for me to get to the troublesome dust.

Does anyone have any good links, tutorials, articles, etc. on how to separate the glass from the display screen?

Thanks in advance for any tips!

Starting around 2012 or so, the glass it glued to the screen. Prior to that, it was held magnetically so you could easily clean things out.

Now, being glued, not sure how any dust got in there.

The process of fixing this involves getting the glue out, so it'll be ugly and likely potentially damaging. So depending on how visible that dust is, you might want to see if it's worth it.

****, I was afraid of that... thanks for confirming the display is glued down.

I'm a bit puzzles myself on the dust...maybe I should take a closer look to see if it's an issue with the display itself.

Thanks!

Yeah, you might be looking at a stuck pixel(s) than dust. But yes, lots of people were annoyed when the glue came into effect.

I saw a bunch of videos of people using heat guns to allow for the glass to be separated and enough videos of the heat cracking the glass requiring a full new screen (glass and LCD) to replace it.

Maybe you could find a nice desktop photo to use that might mask or cover the apparent dust specks so that they are hardly noticed???

I just recently changed my desktop to a much darker photo which increases the contrast of what I might have on my desktop and makes it much easier to see and read.

Of course I have some trouble with my eyes and just had some recent eye surgery as well, but the darker desktop photo improves things dramatically, along with a lower resolution I have been using for some time.

I'm not sure how the dust gets into the display, likely through the display rear metal shielding, but it certainly does. It's usually very fine, mainly causing dark patches in the display corners. It's quite common. I see it more in iMac's that are extremely dusty inside. The only solution I have is to replace the display when economically viable. If you can see individual dust specks it's not what I'm used to seeing. I have also seen some large chunks of debris in the display, along with clusters of dead pixels, not so common.

Dust ingress in the iMac displays from 2009-2011 would look like a cloudy sky when powered up on a white or light coloured image. The dust would be within the display, not behind the glass.
