Backlight failed, need help identifying fuse or capacitor


I purchased this laptop with a problem (green line on left side of display) and decided to change the lvds cable since reconnecting the original cable improved the problem almost all the way. I changed the lvds cable and found that the backlight did not work so I changed back to the original which produced the same result (Computer boots, image on screen, works fine connected to external display, just no backlight). After close inspection of the new lvds cable, I noticed that two of the pins on the right side (if holding connector so pins are pointing away from you) of the connector end that plugs into the logic board are damaged. I should have checked before inserting the new cable :( Anyways, I removed the logic board and inspected it. On the side opposite of the board mounted lvds connector, and directly opposite of where the damaged pins connect is a shorted fuse or capacitor I need help identifying (please see photo). Please help, and please let me know if you need more information. Thanks in advance!

Thanks for your help! Do you have access to some kind of schematic? I'm interested in learning where the WLED chip and fuse are located as well.
