I have dust AND an insect between the glass and LCD panel on a 27" Late-2013 iMac which was gifted to me.
I have already upgraded the CPU in it to an Intel i7-4771, but held off re-gluing the display panel back on prior to evaluating the stability of the system with a much higher powered CPU than it originally shipped to me with.
The cooling solution is actually inadequate for the beefier CPU when it runs for a significant time, despite maxing out the fans, it still throttles way down.
I will probably have another go to get rid of this beastie:
and the dust:
Both are absolutely beneath the glass and above the LCD.
I know how to take off the screen, but the problem is: how to disassemble the screen itself to clean the outer panel?
Hello, I have the same issue, it would be great to find out if the screen/foils can be taken apart after the removal from the bezel. Thank you!
The cover glass and the LCD assembly are glued together. Its just not possible to take apart without making a bigger mess.
A problem people think is dust is in fact screen burn in. I'm sure thats your issue here.
Screen burn-in is NOT possible on a LCD panel! Dead or stuck pixels can be a problem on a LCD panel, but not burn-in. If the panels were OLED, which they are not, you would experience color fade and burn-in. Because it uses organic dyes that fad over time, especially the blue for some reason. Unlike LCD panels, OLED panels will not stand the test of time. 20 years later the LCD will work, where as the OLED will be hard to watch what it’s displaying! My point is that you are incorrect on it being burn-in and most likely it is indeed dust under the screen!
@helliant1 Actually, that is incorrect. LCDs can get screen burn in just as easily as any other display can.
