So, I got this nice iMac Bondi Blue, free, from my school. The only thing wrong with it is that, you guessed it, the flyback transformer is shot.
This is a Rev. A, tray-loading G3 at an incredible 233 MHz (don't worry, I'm posting this from a Mac Mini, with 1 GB RAM), and I get the Mac-VGA adaptor, plug it into a monitor, power it on-and-the external monitor doesn't wake up from sleep, just plays the test pattern. Tried it with several monitors, new and old.
Can someone show me the proper setup for this? I've never seen an actual picture of what you're supposed to do.
That'd be great, and if you'd like, I can show you my current setup, too.
Thanks, guys. This is my first post, I hope you can help me and I can help you.

A couple suggestions:
1: Make sure you have "multisync" Mac/VGA connector, like one included with a "recent" (last most-of-a-decade, basically) monitor. The dirt-common VGA-res-only ones floating around for Macintosh LCs might not work, as might not the complicated switchy-dial ones.
2: When you first hook this up the Mac will output an oddball refresh-rate display. Old "cheap" monitors, particularly 14" ones, will probably have issues syncing with it. Although I haven't tried it my guess is there's a good chance you'll have problems with an LCD monitor as well. Your best chance of success will be with a new-ish 17" or larger CRT. Once you've gotten it up with that you should be able to set a more sane and compatible display mode.

(Edit: Note when I say "I haven't tried it" I mean I haven't tried hooking an LCD monitor up to an iMac motherboard immediately after it's been running the internal monitor. I've done it with CRTs many a time, alas.)
M'kay. Well, I've tried it with 5 different monitors now, LCD, CRT, all the same thing. No effect.
I've got a dead iMac, and it's got a brand new flyback transformer in it. I'm thinking its the power supply.
What does your iMac do when you start it up with the internal monitor plugged in? If it does absolutely nothing, I'd guess it's a power supply issue. If it begins starting up, gives a pop, then shuts down, that's the flyback. And if you've got a dead PS, it won't matter what monitor you hook up to it.
It's definitely the flyback.
I'd give a video, but that would just waste web space.
Actually, the computer boots up fine with an external monitor, the apple noise happens, it boots up, you can hear the OS booting, the monitor just doesn't turn on.
So I'm thinking it's something to do with the video card, or something.
Yeah, that's what is does. I know it's the flyback in the internal monitor, just don't know about the external.
EDIT: And obviously these monitors work outside of the iMac, xP
