I have a 2.4 G iMac that apparently was struck by lighting, I've replaced it through insurance with the 2.8 G (of which I have another small problem) Anywho, I found a service manual and tried the RAM didn't work. Opened it up, I have the first LED on the MB when I go to power it lights # 2 & 3 flash and 1,2 & 3 go out. Any suggestions before I part with it?

one more time but faster...

Can you explain it in a bit more details?

The machine at first sign of the problem. When you pushed the power button you could hear fans, but no gong, no screen. You had to hold the power until the machine shut down, about the third time of trying there was no response at all. This is when I took it for repair, they said it was struck by lightning which we did have a storm that day. (I don't know how well they looked at it!)
After finding a service manual I walked through the steps in the manual:
1. Replaced the RAM, still no response.
2. Open the machine to view the 4 LED lights on the MB.
3. Connect the Power Cord and LED #1 comes on.
4. Depress the Power Button, LED #2 & #3 flash and as #2 & #3 go out #1 goes out as well.

Another note when the power button is depressed the screen does slightly flash.

I'm a newbie at this... never had an iMac apart so I don't know what other details I can give you. It was deemed irrepairable so I thought I had nothing to lose.

Have you tried resetting the PRam, (Command + Option + P + R) right after you press the power button (keep em held down til you hear 3 gong sounds).

Not able to zap the PRAM as soon the Power Button is touched the power to the machine is non existant.

Sounds like it needs a new power supply, by the looks of it. (Though it should be examined by an AASP prior to spending money on any replacement parts.)

It has been looked at by a AASP but I have my doubts as to how in depth they looked into it as my mistake was telling them off the bat that I need to know whether or not I should claim it on insurance.

I would also like to know, if the hard drive is OK will it work if I put it into a G4 Blue Tower.

No. The iMac uses Serial ATA drives whereas the Blue and White G3 uses standard PATA drives.

Thank you Lars,
Do you have an idea of what a power supply is worth?
Thats what service manual said it is too, but I needed someone else to think the same.
The machine is only 5 months old and if I can get running myself would be super.
