Right, I've currently had my iMac for at least half a year now (I think it was August last year i bought it) and I've been throughly happy with it until now. I've noticed something that resembles screen burn at the top left corner of my screen (it's like a gray and black Aurora effect) and I've also noticed that the colour tone (correct me if I'm wrong) when viewing a gray screen seems wrong towards the right of the screen, almost like water splashed on paper. Secondly, I'm having problems trying to run Windows, I've started another thread where it's properly due named "Crashed Screen when booting any DVD Disc except Mac OS X" in the Windows on Mac category. So my questions are: 1. Should I take my iMac in for Repair? As there is both screen burn and problems installing other OS's 2. If so, would it be a good enough problem for repair? It's still under warranty 3. If not, is there anything i can do to fix the screen problem? As i said the other problem is in a different post, might get an answer there Thank you for your time. NOTE: The pictures were taken while the screen is off, iMac turned off so the burn could be seen better.
