I replaced a power supply that failed. The onboard LED indicators are telling me that everything is functioning until I connect the LCD display power cable. Then the power supply fails and all of the LED’s turn off.
Do I need to replace the display or is there another issue?
From what I’ve read it seems the issue could also be the inverter. I don't know enough about computer hardware to know what the inverter looks like or how to test it.

The inverter for the CCFL lamps is part of the front display assembly. Its the same layout as seen here: iMac Intel 24" EMC 2111 Inverter Board Replacement. Apple never offered it as a replacement part. But here’s one source iMac 24" Inverter Board - Mid 07/Early 08 - Recycled
