I'm hoping this can be a repository for specific repair help/information for the Powerbook 3400c. Macdrone has been doing sort of research/experimentation on repairing some of his logic boards. I now have two 3400c's and various associated stuff.
First off, at least for me, is the power board. The two I have whine when plugged in. The one I just got has the caps light come on when plugged in, and a sort of speaker pop that my other one does also. So I'd bet the 'new' one also has power board issues, although I'm hoping it doesn't. Based on visual inspection, I had assumed some of my rectangular ceramic (i think?) [C2 and C4, and C27-C29] caps had gone but Macdrone suggested C49 and C15 - the big and little cylindrical ones on the top.
I'll report back when I get the new 3400c. And I'll report back again when I'm able to get a new soldering iron.
