Hi,

The brightness control bottons are no longer working anymore on my powerbook Duo 280C.

I opened up the LCD housing as I though it was probably the brightness actuator but it tests good.

I had a spare logic board from a duo 280 so took a shot and swapped it to no avail, but we can exclude the logic board now.

I only see 2 possible options left: the inverter board or the LCD cable.

I'm toast anyway as these parts never come for sale on Ebay xx(

Anyone else with this problem ?
