[QUOTE="chscag, post: 889279, member: 46727"] You could have fried something when replacing the power supply if you hooked it up incorrectly but I would think you would find that out immediately after turning on power. Hopefully you made a diagram of the old wiring and placement before removing the original PS? If anything, the inverter (which supplies power to the backlight) may have been zapped or not hooked up to the power supply. Or, power to the display itself may not be hooked up correctly. That's why you need to go over the wiring again. As for attaching an external display, your G5 supports video mirroring only but that will be good enough. If everything else is OK (power supply hookups) and the video is working, an external monitor should work. Normally, you will have to go into System Preferences, Displays, and setup the external monitor. What version of OS X is the machine running? Regards. [/QUOTE]
