iBook display problems


The LCD on my original (Tangerine) iBook is having problems. It's as though the power is fading - little brownout-like burps in brightness. It does seem to get a little better after warming up but the problems don't go away. They just get less frequent.

I've observed the behavior with the battery and with AC power. I've followed the instructions to reset the power management, but it seems to have had no effect.

The problems are new. They began about a week ago, just after returning from a vacation. We flew, but I kept the iBook with me (not checked) so I don't think there were any pressure or temperature issues. It is the first time in a long while that I used the battery for extended periods, but not more than about an hour or two.

Any ideas for a solution? If not, any ideas regarding repair/replacement?

Thanks in advance,
