Will not boot/Black screen
I have a late 2006 white 20" Intel 2.16 iMac that will not boot. LCD stays black and there is no chime during the boot process. The first 2 diagnostic LED's both come on but the 3rd never lights up. I have attempted to hook an external monitor up and still no video is displayed. At this point I have replaced the logic board, the inverter, and the power supply. Any thoughts on where to go from here? Is it the LCD display itself of a possible dead CPU?
Is this a good question?
