You are so right about that, the rosin core flux actually spilled a bit into the screen and it looked like a small blob on the screen ( I always taught you can never use too much flux but in this case i did lol). I didn't realize this until i turned it on, the fix up actually made it look worse! I taught I messed up the polarity of one of the capacitors initially since it looked like a burned spot. I was about to give it up when i decided to pull the whole thing apart, the flux actually got sucked up behind the glass and the paper cover sheet. Took me a while to clean up but screen looked good as new once i did. I would have been easier to solder with the plastic piece removed but that is also a hassle on the LCD since I didn't want to deal with dirt getting on the glass. Regarding the original caps I always clean up with cotton swabs and make the original pads and surrounding areas as clean as possible so shouldn't be an issue there. btw I pulled a third powerbook and the LCD screen looks like it has a pink spot on it I hear this is common for the powerbook 100's from an old thread on here.
I didn't realize there were multiple versions of this board. I think mine are newer since nothing looked like it was modified or tweaked. Both original hard drives still boot and have some nice old games I was fiddling with. I also took 3 of the power bricks with me to work last friday and cracked them open using a technique from a user on 68klma here, plastic didn't break! Still on my waiting list for recap, Sometimes I wish I had more time for this hobby!
