Hello all I am having some difficulties right now with some apple products and I am running out of options. I have been building and repairing PC computers for years, I don't do it as a job but as a hobby. I am no where near an expert or anything. A coworker who noticed I know computers a bit asked me recently if I could fix his iMac 21.5 / 3.06 / 2x2gb / 500gb ----- (So the MC508CA). So the iMac has this screen issue where it powers up and gets to a kind of weird multicolor screen, then it turns gray and it turns blue. I did some reading online and apparently this model had some factory hardware screen problems with some connectors/transistors which does that to the screen...They were suggesting changing some physical stuff inside on the mother board. I did not feel like opening it since it seems pretty complicated, so I just ordered a cable online that would take the iMac screen image and put it on another screen. So his iMac would become like a tower computer with another screen. Problem is... It copies the buggy image =( I was sure it would project a non buggy image on the other screen. So I don't know what to do anymore. It seems the hardware is broken and I can't project the image '' correctly '' on another screen... Anyone have any idea what to do with this?
