This is a fairly common problem, generally caused by a flaky connection somewhere. This diagnosis becomes much more certain if (gentle!) flexing of the display frame changes things. Often, simply removing and reinstalling the cable(s) (at the panel, and at the motherboard) fixes this problem. In other cases, the contrast control itself develops a problem. Vigorously moving the slider back and forth will frequently fix that. The inverter board controls power to the backlight, which does not appear to be your problem. Resetting the power manager will not help, unfortunately. But doing so is easy and harms nothing, so go ahead and give it a shot. :-) --Cheers, Tom -- Prof. Thomas H.
