Hi guys.

I have an iMac and have started to notice dust collecting in the corners of my screen.

It is a slightly darker area on the screen and I think it is dust or some form of marking - i do not think it is a backlight problem.

The unit is far out of warrenty - does anybody have a good guide on opening + cleaning the inside of an iMac screen?

Cheers,

What year/model is it? (Makes a difference)

Contains: FCC ID:QDS-BRCM1024

2006 I think...

No help with this then?

I've got no experience with that model... I stayed silent hoping someone that knows more would chime in, and they likely will still All I could find from a quick google search was this... Installing iMac Intel 17" Display - iFixit Now... I am not suggesting you follow the guides there, I have never used them, but it's the best I can offer with no experience on that model iMac. Hopefully someone else will chime in with a better answer for you

Some air from the fans might be coming inside the computer through the LCD screen. The glass is really easy to take out and clean it out with a really thin cloth.

Ok - can you post a guide on how to get into the screen and clean it safely? It may well be easy - but only when you know how!

Already did above but will again now.... Installing iMac Intel 20" EMC 2105 and 2118 Display - iFixit

Unless of course that's not the same model you have?

(I realize that guide goes deeper than you need to, but I believe it shows how to get the front off, and get at the glass )

Hmmm... Looking through that guide, it looks like the display/glass are one unit on that model? I thought the glass came off with the front bezel... Similar to how on the newer iMacs the glass is independent from the display underneath it... Apologies if I was wrong.

Having taken the main casing off I have decided its probably screen bleed So it will be a replacement panel if it becomes a problem - which it doesnt look like it will be at the moment.

Oh, sorry to hear that I hope it won't be a problem! Was it difficult to get the casing off? ( Just curious )

It was a bit of a pain getting the 2 top latches undone to be honest but what more to expect - its about as much of a pain as undoing an xbox 360 case if you have ever done that!
