The 24-inch 2007 iMac has four diagnostic LEDs on the logic board that can help to troubleshoot the computer. The four LEDs are located to the right of the memory slot, between the memory slot and the HDD SATA connector. A little disassembly is required to be able to easily observe the LED's. ** LED interpretation is also applicable to the iMac Intel 20" EMC 2133 and 2210**
