Brightness Shutdown Problem (Even After Inverter Replacement)
i have a white Macbook Core 2 Duo, model A1181 (Santa Rosa i think), with a brightness problem. it all started when it would shutdown the brightness randomly when it was active or idle. after doing some tests and research, i've noticed that, after the brightness shutdown, decreasing the brightness (via keyboard) to it's minimum and then increase it (via keyboard) would turn the brightness on again. i've also noticed that if i put the brightness to it's maximum that would shutdown the brightness after a few seconds, if it stays one level before the maximum (or lower) it stays on until i do something like touch or move the screen lid (up and down). if i have the power adapter connected it's more difficult to make it shutdown the brightness...only with hard screen lid/notebook movement. connected to an external monitor , the problem only happens to notebook's screen as expected.
i've read many pages and forums and it seems the common procedure for this problem is to replace the inverter. so i've replaced it but the problem didn't go away. so i might try to switch the inverter cable now, but maybe you have a better suggestion.
Is this a good question?
