Well, I wound up using this machine as a CRT donor to fix his other machine that had a CRT with some deep gouges in the front glass from being set down screen side down on the ground at the dump where it was found. That machine is a tray-loader and should be much more reliable in the grand...
I'm going to try heating the board up with a hairdryer, I can see if getting things warm allows it to power on. If it does, I'll go ahead and replace the caps. If not, It's likely the flyback and that's unobtainium unfortunately.
Hi all, I'm looking at a 350MHz iMac for a friend. It doesn't power on when the button is pressed at all. I can hear the high voltage come up for a second, and then slowly discharge when the button is pressed. The Power LED doesn't come on, or even flash. I don't hear the CRT degauss. I do...
Yes, if the hard drive shows up on the desktop. Open the hard drive, and then the System folder, and then Control Panels. Remove anything related to the screensaver (I would move it, not delete it, just outside the system folder). Then, do the same thing in extensions. Then see if it boots.
Not sure why it failed, but those voltages look normal to me, as lead acid is normally higher nominally than the 6 volt label, and charge voltage a bit higher than that.
Is this on your Quadra 650? If so, it has onboard Ethernet. You should get an AAUI to RJ45 transciever so you can use Ethernet instead of burning CD coasters.
TattleTech. Super useful for hardware related stuff. Also the SetDate utility, because otherwise you can’t set the correct date and time on anything older than OS 9.
Also, please use sockets for swapping chips like this. Much less damage to the board if you have to make changes and makes finding bad chips much faster.
