Why do I have no backlight after replacing the LCD?

+Hello and thank you for you help!
I'm working on a friends Mid 2011 EMC 2353-1 MacBook (for free) because it seemed to be a simple fix. It had a slight crack in the glass cover of the LCD from being closed with something laying on the keyboard. A few moths later she reported the display stopped turning on. The laptop seemed to turn on and make the starting chime but still no display.
So taking a quick look at it with a flash light I noticed the backlight was the only thing not working so it must have just needed the LCD and glass to be replaced. I've done it before and it was no problem (I love my Ifixit tool and repair kit). After replacing everything and doing the test start I still have no backlight...
After doing some more research it seems that some similar models have some type of problem with a circuit on the mobo that can be replaced but none of the diagrams or forums really depicted or directed to one for this model.
Could anyone point me in the right direction of what to do next? Thanks again! -John
P.S.
I looked up the serial number and it says "EMC 2353-1", But it says "EMC: 2417" on the motherboards RAM slot.
