Screen goes dim after 10 seconds.
I have a Macbook A1181 which starts up okay but after about 10 seconds (just after the apple logo appears on the grey background)the screen goes dim.
I can see the picture faintly on the screen and if I turn the screen brightness right down and then back up the screen is lit but then goes dim again. I've changed the inverter and the problem persists.
Is there a sensor or switch that may be at fault or could the screen be at fault?
