Default ATTN NOTEBOOK Repair WIZARDS----------Anyone know how a Notebook Screen backlight circuit works?

I have a notebook with a bad backlight. I can trace small level
signals on the 6 pins into the inverter board but have no high voltage
output. This notebook has capability to dim/brighten the backlight.

The inverter costs $100 so I would like some way to verify signals
into the inverter are what they should be but have no idea what they
would be. Can anybody enlighten me please?
