its most likely the backlighting fuse, or its possible that the LED driver may have taken damage when the cable was broke.
The quick way to tell is boot the machine, and hold a flashlight up to the apple logo on back of the display housing. If you see an apple logo, good news. You have video, but no backlight.
If you can find a local place that repairs computers to the component level its an easy fix. If you can give me the serial number off the logic board I can tell you where they can find it and replace it.
hey trent you got the right numbers. You clearly have video information, what's missing is backlight. The most likely cause is the backlighting fuse, but the LED driver also could have issues. I can post where it is from a photo on this site, however, Scott D told me that I could direct you to my email in situations where what I need to give you isn't something they want posted publicly. if you checkout my profile you can find the email.
unfortunately you pretty much have two options:
1. replace the logic board..you are looking for: LOGIC BOARD 820-2530-A
here is a link to one I found on ebay at a reputable dealer. http://cgi.ebay.com/APPLE-MACBOOK-PRO-A1...
2. find a shop that does component level repair on mac's and they can fix it. You will most likely pay the cost of a liquid spill, but this will warranty the item and assure any other area's affected are fixed. However, depending where you are from you may be able to find a computer repair show that would replace the fuse for you for under $100
3. Attempt to fix the board yourself.
