I used to be on this forum way back in the day (early '00s) under a different username, when I was in high school. Crazy to see that it's still around, and so active!
Anyways, I recently got my first classic Mac in a long time, a clamshell iBook that someone gave me for free as not working. A reinstall of Mac OS 9.2.2 seemed to get things going again, and then I upgraded the hard drive and resoldered a couple of broken connections on the single USB port. Back in Mac heaven, right? Not quite.
Almost every time I boot it now, the display backlight does not come on. It used to work right almost every time, and now it fails almost every time. When it fails, it boots properly, and I can see everything come up super dim. This seems odd to me, as when it works, it works great, with plenty of brightness. Resetting the PRAM (Cmd-Opt-P-R) and resetting the power module with the little pen switch near the power button does not seem to help. The only other symptom I've noticed is that when the backlight does not come on, the computer seems to get hung up for a long time when shutting down (hit power button and hit enter, or select from Special menu).
Any ideas? Does this seem like an issue with the 0.33F supercapacitor, the inverter cable or board, the backlight tube itself, or something else?
Thanks!
