Computer won't boot if PSU is plugged into LCD screen
Hey all,
I'm trying to repair a late 2007 intel iMac 24", EMC 2134. I opened it up and checked the LED lights: they were all off. Because of this, I thought it needed a new power supply unit, so I ordered one on ebay and thought I was good to go.
Cut to this afternoon. I replaced the PSU, plugged in the appropriate AC in, DC out, and thermal sensor ports, but I left the LCD screen unplugged from the PSU. The computer boots fine, and all diagnostic LEDs are green. In fact, the PSU wasn't the problem at all - the old one works great. However, when I plug the LCD screen into the PSU, the computer is totally non-responsive, won't boot, and none of the diagnostic LEDs are on.
So I'm guessing something in the LCD is shorting out the rest of the computer. Is there a way to fix whatever individual component is fried, or do I have to replace the screen? And if so, does anyone know where I can find that part?
Thanks again!

any chance you can find a manufacturers number or a model number on the panel? That would allow us to find a datasheet and we could check on that to see what might give you the problem. of course, do check your connector on the board, just to make sure that it is okay.
