iMac 27″ screen displays dark stains, spots and patches

November 15, 2010 30 comments

My iMac 27″ which has performed flawlessly since I acquired it in March of 2009, has started to develop dark patches here and there, across its once pristine façade. And this pisses me off, mightily.

It all started in summer of 2008 when my first iMac (the new Intel Aluminium 24″ iMac) started to develop dark stains on the screen…

There were various theories bandied about, such as overheating, condensation leading to mould, dust sucked into the system, etc… But my  room is airconditioned and on the 9th floor of an apartment, above the majority of dust and grime. And although the room sometimes reached 35 degrees (right on the edge of operating spec) or so, there was never any condensation and I always used air conditioning when I with operating the computer.

Before discussing, let me fill you in on a little background with this post:

So you can see that I have a history of nasty screenage.

The effects are not so great that the screen is unusable, but in my experience these things never improve with age.

So, here we go again, it is with a sense of deja vu and disdain that I contact Apple this afternoon to see what can be done.

Here’s the money shot:
