This guy knows the deal >>8567937, I never actually dealt with any back in the day, but I was a kid using my Mom's Mac and Macs at school. As far as your iMac, the CRT would be dead, but as someone else mentioned interally they use VGA, and some actually have a VGA port on the back under a door, I would see if you have the latter and if so, plug it into another display to verify if the logic-board is happy. Unfortunately I don't think you're going to want to replace a CRT, but if it's working otherwise you could remove it and replace with an LCD or just run external if possible. I did that with a Mac Plus recently, just turned it into a really ugly minitower since the CRT and analog-board had died.
