iMac G3 Screen Doesn't Work.

[RaptorX]

Alrighty, long story.

I installed Ubuntu Hoary Hedgehog on an iMac G3 a while ago. It had problems with the time (since the battery that keeps the time there is dead), so I re-installed Mac OS 9.

It went fine until restart, and the screen didn't work. I've just been using it with an external screen attached to it.

Sometimes, if you boot it up, you will get the screen to work but with only one color (every thing's red, blue, or green). These occurences usually are after 50 or so bootups. Also, when the screen is working in one color, it never can display anything graphical, only text.

So, I'm just wondering if there's a way to reset the screen by software. Can any of you guys help me?

Thanks.

Sorry for bumping, but I'd really like this problem fixed.

Do you know what model it is? The Slot-loading ones had a daughterboard style screen controller that was a bit flaky.

Yes, it's a slot-loading blueberry iMac.

Is there any way to reset the screen through like Open Firmware or something?

Do you know what version of the firmware it's running? It's possible that the Linux install has similar effects to an OSX one, in which case the iMac needs Firmware version 4.1.9.

I'm running Kubuntu Linux on it right now.

Is there any quicker option? If not, I'll just go back to Mac OS 9.2.

Could you not make an OS9 boot disk rather than rebuild it? A Zip drive is perfect if you still have one of those knocking about.

Not that I know of. I'll just start over.

I'll report back with my results

Interesting.

I reinstalled Mac OS 9 and it completely fixed the screen. But, when I shut it down and rebooted it, it is back to where it was before. I've rebooted it six times no to no avail.

Okay, sorry for the triple post, but I fixed it!

Thanks, man for helping me!
