For what it's worth, this (for me) is the way pb100's seem to die. It's like the contrast is "stuck" all the way up, right? All the pixels on the display are "on". Brightness works OK. I have 2 in a drawer that did this. I've swapped motherboard and lids around with working units, and thought I'd decided it was MB related, but other people on the pb100 list (the Stanford one) reached the opposite conclusion :) (it's been a long time, I think that was my conclusion anyway ;) I have disassembled the display on the 100 and turned the contrast knob, and the pot did still work, but I have no idea about any other little components. There may have been a couple resistors on that circuit board (with the controls) I could have checked, but I didn't check them. The only fix so far for me, for this: ship it across the country UPS :) My father sent me his pb100 with the contrast problem, it worked for a couple weeks afterwards then the issue came back. Lots of joggling around might have fixed it so I resoldered every solder connection on the MB, etc, similar logical things to check for bad contacts throughout the machine but nothing really helped. Good luck, I think you get to open it up and poke around, or you could try the UPS thing :) Brian -- PowerBooks is sponsored by <http://lowendmac.com/> and...
