So my iMac took a power surge and stopped booting. I believed the problem was the power supply. I ordered the proper power supply replacement from iFixit (my EMC number is 2134, which led me to order a power supply for EMC 2211)) and it came today. The iMac is a 2008 2.4ghz 24", and that is exactly what it says on the package. Just a few minutes ago I installed it, and voila, she booted up! But then, smoke started pouring out from under the display. I immediately disconnected the power and removed the display to find that a piece on a pcb that appears to be the graphics card is burned and smoking. The part, pcb and back side of the display are scorched. Can anyone tell me what the problem might be? I could only imagine that this is the wrong power supply and it is over powering the graphics card, but iFixit's website said that this is the right one, and the packaging matches. I hope I haven't burned out the graphics card now, and if so, I'm thinking that it will be on iFixit to replace it. I'm going to send them an email tonight or tomorrow, once I figure out what exactly is going on here. Thanks for any help that you can provide! This is the back of the display. You can see in the center what is burned. Close up.
