I just ordered the CCFL at $10 plus $10 for shipping. I will give it a
try.

There are four wires from the board to the inverter.
I only get reading from the red and black wire, 12v dc. No reading for
the other.
Is it possible to make it active high in case it is the controller
problem?

Yes, it's possible. However, there are two wires for control; most likely,
one is used for dimming, and the other for switching on and off the
inverter. I may be able to help you, but I would need the data sheet for
the inverter - a schematic would be best, but even the pinout would
probably suffice.

A search on the part #KUBNKM011A you gave revealed nothing except places
that are selling them. If you can find a pinout, I could probably help you
further. As a last resort, you could isolate the two signal wires one at a
time, and try connecting them to +5 volts one at a time. You've already
located the +12. I would not assume that the black is ground (I remember
the good old days when this was almost always true. *sigh*), do a
continuity test between the three remaining wires to ground - a negative
lead on a surface mount cap is usually a good point for this, as is a
shield on a connector housing. This will leave you with the two control
wires to experiment with.

Good luck.
