I just got an iMac G3 400MHz DV Indigo at a garage sale. I wanted to try out a Mac and wanted to see what OS X was like.
I turned on the computer, and all I got was a click like sound from the speakers and a click like sound from what I think was the CRT. The led on the power button does NOT light up. That's all that happens. I can hit the button forever and thats all that will happen.
So I got the service manuals from the web and took it apart and read the section on checking power voltages. I checked the current of the PRAM battery. It registered as 3.63v so the battery is working. Then I hit the reset button for the PMU chip. When this didn't do anything I continued with the voltage tests.
I checked the +5v trickle power, the Down Converter On voltage, and I checked the Power Board Fuse. All are ok.
The service manual says that after all those the next thing could be that the Power/LED switch board is defective.
Could that be it? I don't have any discs for the computer as the seller couldn't find them. I think the computer is on OS 9. I want to try out this Mac so badly.
