Plugged display cable backwards after cleaning, screen won't turn on

Hey guys,

I was cleaning my iMac and took the screen off to air out all the dust. When putting it back together I plugged the display power cable backwards. Now screen won't turn on and there's burn marks below. I can hear the computer start and the boot sound plays. Screen stays off all the time. Any hope to get it back working?

EDIT: Based on this thread Damaged display power header whilst replacing hard disk drive it's the ferrite chip that is blown. Is this computer repairable?

Tommy. it is indeed the L9000 250 Ohm Filter in what looks like a 0805 package (measure to confirm), that was destroyed. It is vital to the internal display power circuity. Yes it is repairable, but you will have to know how to solder SMD components. The component itself is readily available at multiple places like Digikey.com and others. Hope this helps, good luck.
