  1. Another update: the new speaker drivers I ordered on ebay arrived recently and I was able to install them successfully! (When installing any new drivers, make sure that the red wire is on the left side for each one while you face the speaker assemblies as they would be installed in the iMac, at least for the Graphite iMac G3/400 DV SE). My only comment is that they are very loud, I had to turn the speakers down individually all the way from within the Sound control panel, otherwise, even with the master volume set to near minimum, they were quite blasting. Perhaps 4Ω is too low an impedan
  2. I can now confirm that all three of the iMac G3s are alive and well, but the third's revival was a bit more dramatic than the others, although it may perhaps point to the actual problem with these things (to someone more knowledgeable than myself). It took almost a week to start up stably. When it started turning on, at first all seemed well, but then there were snaps/pops and momentary distortions in the CRT raster. I was worried something was shorting, but I never caught it visually inside and it eventually stopped. (At this point it was not reliably staying on.) However, the display wo
  3. I can now confirm that one of the iMac G3/400s that I had previously revived started right up again after several days of being unplugged. This was the one that had had most of its capacitors replaced though, so I will check the 2nd one soon to compare. Meanwhile, the 3rd one has not been revived just yet, but I installed a fresh battery and reset the PMU, so hopefully that will speed things along. (It's possible it may have revived eventually without, but it has already been a few days).
  4. I really want to know too! I really feel like the PMU chip is to blame, but is it recalibrating or something? Who knows, but it really does take several days, whatever it is... And resetting the PMU by pressing that button by the RAM slots seems to have little effect, at least as far as I can tell. Currently letting the third sit over the weekend without resetting the PMU or even installing a new battery (currently empty).
  5. They are indeed magnetic, but it took more than a firm whack... Definitely glued on as well, but once separated from the original speaker drivers, they should hold on to the new ones with just the magnets.
  6. Just bought a pair the other day actually! The ones that people have linked elsewhere have angled terminals, and those won't fit inside the speaker bubbles from what I gather. Maybe should grab these too, since they only have one pair left currently... I was also able to chisel off the magnetic mounts from the old speakers from one of my units, so we'll see how they fit! Gosh, they are glued on super tight! D:
  7. I have now revived a second of the three iMac G3/400 slotloaders I acquired, using the plug-it-and-leave it method as described above. The second one, not having had its capacitors replaced at all, took a little bit longer, between 4-5 days. I can't say for sure if that's the reason, but I have the third plugged in now, so we shall see how long that one takes!
  8. I have not tried this just yet, but I will report my findings once I do!
  9. It lives! After cross-posting on the Mac Garden's Discord, a fellow user suggested that they had experienced the same thing, but that simply leaving the iMac plugged into the outlet for awhile seemed to resolve the power-on issue. I decided to give this a shot and, after a few days (with intermittent testing), it suddenly sprang to life today! At first it struggled to stay on past the Disk First Aid screen, but after waiting until later in the evening, it turned on—and stayed on! I've navigated around the old hard drive, even run a DVD, and it all seems to be working great. Hard drive is
  10. I'm having the same issue with my newly acquired iMac G3 DV SEs. I have acquired three of them that seem to have been stored for about 20 years inside of a warehouse (two in their original boxes), and which were used perhaps only a few times before being shelved. Unfortunately, all three have exhibited the symptoms as described by @IlikeTech whereby the CRT attempts to power up, and there's a pop in the speakers, but nothing else happens. I actually have replaced nearly every capacitor in one of the iMacs for its logic board, the PSU, the downconverter board, AND the CRT board. Having don
  11. Wow, getting it to work with 7.1.x would be a dream!
  12. @equant Did you end up having any luck with this?
