Powerbook 160/ 165 capacitors

[jwse30]

So I've been reading about capacitors failing in well, everything Mac made way back when. I see lots of threads (here and elsewhere) about Powerbook 1xx screens needing to be recapped, but I don't see much about the logicboards or anything else under the keys. Are they built with different caps? I saw one thread about a 180 that said it was all solid state, so it had no caps. Is that the case with the 160 and/ or the 165?

Thanks,

There are no electrolytic caps on the mother or daughter boards, just on the trackball assembly, inverter/converter board (for brightness/contrast controls), and the display inverter board.

That probably explains why I've never heard of problems with them

i mean i had a 180 that had a tunnel screen and one that was completely fried so the activematrix screens that tunnel make these useless in my opinion

As noted though the screens do need to be recapped. There are 9 plastic encased electrolytics that 100% for sure are leaking.  At lease one of the caps on the inverter is polymer (Oscon) but I usually still replace those as a matter of course.
