HP DV5000 inverter board pins

Thread Starter 
I've got an HP dv5000 laptop with a backlight that won't light up, (but is known to be good).  I've also got an inverter board which is good, but isn't getting power from the mobo.  So, my question is, would it be possible to bypass the original power source, and hack together some type of externally powered input just for the backlight?
 
If so, does anybody know the input voltage and meaning for the 7 input pins for the inverter board, or how to find out?

Don't know specific to your queries but I personally feel that it is cheaper just to replace the whole inverter, and less headache

cheers ...

Well, that's the problem - the inverter board is good, it's just that the voltage isn't getting to the inverter board.  Unfortunately, I'm well past the headache stage, and am just trying to turn this into a salvageable hack and learning experiance.

 

Happily, in doing some more testing, I found that augmenting pin #1, (which was previously getting zero volts of input), with 18v dc did make the backlight turn on successfully!
