    PowerBook 540c screen issue

    Caps are ruled out then. It's either the panel itself or a connection somewhere.

    Clamshell Keyboard

    If there's evidence of a liquid, the tracks in question are likely broken and not just dirty.

    PowerBook 540c screen issue

    That definitely appeared to be an active matrix screen. If it's a 540c, it almost certainly is. Someone COULD have swapped a 520c panel in, but that's extremely unlikely. The screen in that unit should either be a Sharp LQ94D041, a Toshiba LTM09C017, or a Hosiden LCD without a model number...

    Clamshell Keyboard

    Membrane keyboards are extremely difficult to repair, if possible at all. I'd recommend just waiting for a keyboard to show up, I'm sure you'll be able to find one eventually.

    PB 100: Another victim of vinegar syndrome?

    Ugh, yes, it is. It really sucks, because you can't get the right film to repair those. TFT Color displays can be fixed but passive matrix can't. You can sort of fix them, and they will work with the film you CAN get, but they won't look quite right. The only storage practices I know of are to...

    PowerBook 540c screen issue

    That sort of color flickering doesn’t look like it has to do with the backlight, I think that’s a video signal issue of some sort.

    PowerBook 540c screen issue

    My first guess would actually be a video issue on the logic board. It could absolutely be the screen though, so try a recap if it’s a Sharp display. If it’s a Toshiba, or if the recap doesn’t help, it’s gonna either be the screen itself or the logic board. You also have two issues there - the...

    Pin-out M7783 power supply Duo 230

    All with that connector are the same pinout.

    PowerBook 500 Series Battery Rebuild Failure (Oops, all dead EMMs!)

    Pretty sure mine were Panasonic.

    Macintosh PowerBook 145/160/170 battery replacement

    You should really add that thermal fuse, especially if it’s getting toasty. Good work though, I need to rebuild one of mine as well.

    IIsi fault ...

    I do not necessarily think the PSU is at fault for this particular issue, but it MUST be recapped. The IIsi PSU uses ELNA LongLife Series caps which are the single worst in terms of leakage out of any I’ve ever seen. They’re replace on sight and you’ll regret not doing so later if you leave them...

    Compatible PSU for Lombard/Bronze Keyboard PowerBook G3

    Any of the following: PowerBook Duo (all models) - not recommended because they have a Rifa cap in them PowerBook 1400 PowerBook 2400 PowerBook 3400 PowerBook G3 (all) iBook G3 Clamshell The G3 Snow models use the later connector that’s smaller.

    Powerbook Duo 2300c - power on chimes but nothing else...

    Those legs just look like they're bent backwards, I think that's fine. Only booting one in 20 times is textbook bad capacitors. Get 'em changed and it should be stable again, hopefully. They don't have to look bad to be bad.

    SE/30 turning on very slowly

    A PSU taking a while to start up sounds like a textbook case of weak capacitors to me, but with power supplies it could always be something else. Unless you're really good at troubleshooting switch mode power supplies, I'd recommend just recapping it. Console5 has cap kits...

    Apple didn’t get it in their laptops till 1999, they were late in that regard. Apple was never early to adopt USB, they were just early to remove legacy ports (iMac). Most PC laptops from late 1997 like this WinBook is from had USB. 2 ports was rather uncommon though.
