Discharging the CRT is quite tricky and dangerous, it should only be carried out by a qualified mac tech.

Never work on a mac with the power connected!

The gear you need is safty glasses, ungrounded foam pad, needlnose pliars, wire lead with alligator clip at both ends and a CRT discharge tool (if you do not have a discharge tool you can use a insulated srewdriver attached to a wire lead with alligator clips on both ends)

Use one hand keeping the other behind your back. Do not touch anything with the other had while you are discharging.

Once you have taken off the casing connect the alligator clip from the lead to the ground lug on the all-in-one system. Then slide the discharge tool under the anode cap into the anode aperture. As soon as you feel the metal of the probe touching the metal of the aperture, the CTR is discharged.

Try not to leave the machine open for any lenght of time.

Imac 499 mhz boots but no screen display


Hi there
This looks dangerously like a mac I had and it died in my hands because I had it on standby for too long.
Have you looked in all programs and there look for screen-display?
I would try to work it from there. Try to get a brighter screen and so on.
all the best

When I turn on my mac g3 works but the screen stays


Some models of G3 iMac have an external display connector under the rear belly plate. Connect a monitor to this connector. If that monitor shows your desktop, your main CRT is blown. The cost of replacing a CRT in this model is almost certainly more than the residual value of the machine.

IMac G3 Not Starting


Hey, RexKing:

Your problem is hard to diagnose with your current description without knowing where the clicking sound is coming from or exactly what it sounds like, but most likely the problem resides either with the power supply or its connection to the circuit boards. If you have access to any scrapped G3 iMacs to cannibalize for parts at an E-recycling depot, you can probably find just about anything you need, as long as you get the right model, as they changed key components a few times, but, like cars, a lot of parts cross over. The exact model description is on the bottom in really fine print.

In any case, you will have to take it apart to check out the power supply and/or other components, which is a bit tricky without a guide. You can find a really comprehensive Apple iMac G3 service document, for many of the later models, posted at this URL as an 11 Mb PDF file:

http://www.scribd.com/doc/103447/iMac-G3-Disassembly-Guide?autodown=pdf

Only catch is that to download it you need to sign up for a free SCRIBD account. (It's a document sharing co-op site.) Hopefully this won't result in years of spam. Good luck, and if you figure out the cause, please let me know. (I have about a dozen iMac G3s that I am gradually refurbishing.)
