Display backlighting does not work
I have a penryn (early 2008) 2.5 ghz 15" MacBook Pro that I was replacing the rear bezel on. Very simple and straightforward stuff, but now my display backlighting doesn't work, making it nearly impossible to display anything. Nothing seems to be wrong with my assembly, and I'm at a loss as to what could be wrong. Obviously it was something I did, as it operated perfectly before.
Does anyone have any experience with this problem, or have any ideas of things to check?
<Edit>
My LED driver board does not have any outward signs of damage, and I don't think I touched it at all with my spudger, but seeing as its the LED driver board and its in a rather exposed spot, I'm inclined to suspect it. Is there any other trouble spots I should be thinking about?
Es esta una buena pregunta?

The inverter cable seems fine, insulation is intact, all connectors are secure and free from damage, I also replaced the LED driver board. No change in status, the display still has no backlighting. no bright white background on startup (which if I remember right, should be bright regardless of brightness setting). after booting up my brightness is set at max.
obviously its a possibility that it could be the display itself, is there a way to check that short of putting the display in another A1260 MBP?
Could it be on the end of the left I/O board (seems logical possibility as the inverter cable plugs in there)
My multi meter is not small enough, but I will try to check the inverter cable, even though it seems to be in perfect shape.
Thanks for the help, any further advice would be helpful.
