Hello:
Here is my (strange?) advice. Get a grounding bracelet. Ground the computer. Take your clothes off so they do not generate any static charges. At least take your shoes and socks off. Plug your grounding bracelet into the ground pin receptacle in the AC power wall receptacle. You and the computer should be grounded now so it is safe to the computer to be touched. NEVER TOUCH THE C R T! Death may result if you touch the CRT. Make sure that any parts that you are putting into the computer are not put into a dangerous spot such as on a carpet or other potential static charge holding materials. If you do these steps you should cause no damage. Most people do not go this far. When I was working in an Instructional Television facility at a University I decided to start wearing leather sole shoes because I did not like walking across the room and then being shocked when I would touch the case of some electronic device. Such a charge on a memory card or CPU or other internal part would kill your computer.

Sorry to reply to my own post, but I had a further question.... I have another iMac (G3/333, Grape, Tray-loader) I want to upgrade, but can I expect the same results if I pull the electronics tray on the other system? Anything I need to be careful about when I pull the tray from the system?

Many thanks for any ideas!

Not long ago, I got an iMac from a friend (G3/266 Blueberry, Tray-loader). It worked just fine, except for the CD-Rom. I pulled the motherboard/drive package to see if there were any loose connections and see what kind of drive I might have to replace.
Put it back together and it wouldn't start up again.
Symptoms:
Push the power button, it turns orange and the startup chime sounds. After about 10 seconds the power button turns green and then the system powers down. After this happens, the system is completely dead. If I disconnect the power cord and disconnect the internal,15 pin video cable for a minute or so, I can get the system to go through the cycle above.

If I connect an external monitor, the system works okay. I =know= this appears to be the "dreaded flyback" problem, but how can removing and re-installing the electronics tray cause this problem? I called a Mac repair tech and he said I "probably damaged a wire". Okay... what wire? Do y'all think this is a simple problem or do I have a major repair on my hands?

Appreciate any and all suggestions.

Thanks,

Amanda
