Chosen Solution

I have an intel 2.16 24" iMac and at the top of the screen there is an upside-down sun burst of dirt between the LCD and the protective plastic that covers it. Is it possible to separate the actual LCD from the plastic so I can clean the stripes? This is the older white plastic “Pizza Box” version.

On this iMac model there is no extra part between the LCD and protective film. This seems like something on the LCD. I would think you have to change the LCD. This is not very difficult and you can find a good used on on ebay. I found some for you here: http://shop.ebay.com/i.html?_from=R40&_t… The Apple part no. is 661-4184 (see the parts here: http://www.welovemacs.com/apim242inco2.h… ) Here is the guide. Take your time and use your fingers a lot, don’t be tempted to use force. iMac Intel 24" EMC 2111 LCD Replacement
