iMac G3 - not booting (6 sec shutdown)

Ok, I've been looking around on a few forums, and I've tried to reset PMU, hold the programmer key, take out battery let it be, external screen,...

None of it worked for me.

I have tried to install Os X Jaguar without upgrading firmware, so it told me that it needed to upgrade.

But I can't do that since it doesn't boot anymore. I tried disconnecting the harddrive and boot it without it, it still turns off.

I even made a video about the problem:

yes looks like the power supply , otherwise the cd would come out again when you press this small button like you did
and never ever pull the plug as long as the light is on thats deadly for the iMac ..in fact for any computer ,
think of it as the life support machine , if you pull it out the patient dies
Intelligence does not need Intel inside,
All it needs is good sense outside.
