If so, replacing the inverter board is a good starting point. Doesn't the
inverter board also control the backlight? If not, why does Apple
recommend replacing the inverter board when you have a faint picture with
no backlight?

As far as I can remember, if following the Apple repair manual, you have
to remove the display and motherboard. Not necessary?
