    What iMac do you have, G4, G5?  Do you know the model identifier for it?  If not, how old is it? 

     

    If you have a G5 iMac, any model except the iSight version, you can take the back off the iMac pretty easily, and visually inspect the capacitors to see if they are okay.  There is a high probability that you have ruptured, leaking, or bulging capacitors, and they are the problem.

     

    Apple will not work on this computer as they consider it obsolete.  Google G5 capacitor kits, G5 capacitor repair, and you can find info on fixing this by yourself, or through a non-apple third party.

     

    Good luck.

    Try running the Apple Hardware Test that came with the iMac.

     

    1) Insert the Install Disc 1 DVD that came with your computer into its optical drive.

     

    2) Restart your Mac by either:

            Selecting Restart in the Apple menu.

            Pressing the Command-Control-Eject keyboard shortcut.

     

    3) Immediately press and hold the Option key on the keyboard. This invokes the Startup Manager.

     

    4) Release the Option key after the Startup Manager appears on your display.

     

    5) When the wristwatch progress indicator disappears — indicating that the Startup Manager's scan for bootable volumes has completed — select the Apple Hardware Test volume.

     

    6) Click the right-pointing arrow. Your Mac will start up from the Apple Hardware Test volume.

     

    That should indicate exactly where the problem is.  It might be bad RAM, Graphics Card, LCD Screen, etc.

     

    Good luck.

    That's not a user-fixable problem. A number of iMac G5s have this issue; see this overcrowded thread:

     

    Vertical line issue - How can we get Apple to address this?

     

    Most of the affected models has serial numbers starting with "W8." It's a major repair taht may not be cost-eddective today.
