Hello, I have an iMac (Intel Core Duo, EMC:2104) that seems to have a broken screen. Here are some pictures. Note that the screens in the pictures somewhat differ from one another. It flickers in some areas (usually in the black part) especially when I run my mouse over the area. I connected the computer to another monitor and it works fine that way. Does anyone have an idea what could be broken? Is it the inverter or is the panel broken? Or could it be that some cables just got loose?
