WOW! you always seem to find working machines, or have you repaired them ? Those power caps on the invertor board should be replaced, they will blow the invertor if the fuse doesn’t catch them first. The PowerBook 160 and 180 are very well built and the design is really nice. The trackball is great to use, I had a 180C but had to sell it in favour of a Compaq 5280.
Your photographic skills are great, how do you get such clear photos, I guess you are using a lightbox.
This one had broken display – I replaced LA5316 power regulator chip (from broken Toshiba T1200XE screen – it is where cross brand hobby pays off 🙂 and of course I recap all the electrolytic capacitors. But I try to make photos of the original boards before recapping. Thanks for the good words about my pictures, I do appreciate that. I use also vintage these days Nikon D80 with SB-600 flash which I turn back and this is in a small attic room so light gets well dispersed. But this camera lenses start having uneven focus. I plan to upgrade to D7500, but there is always something more important to buy, like, a new computer 🙂
How did the broken display issues manifest? I’m having screen trouble (serious intermittent distortions) with my PB 160 after recap and this makes me curious if it might be the LA5316.
As far as I can remember it did not show anything at all. If you experienced horizontal portions or lines of the screen black or off, this is likely one the driver chips that are around the screen that control these lines. Or a connection of the screen to the chip. Hard to fix and maybe impossible depending on how well everything is integrated together.
In this screen the troubles will be likely in vertical parts not horizontal.
