Question about Apple Computers & Internet
This could be any of a few problems. Firstly, re-set the SMC. If there is no change to the display proplem, connect an external screen to the iMac to see if there is any display shown on that. If there is, the iMac screen or the inverter is the probable cause. If there is no display on the external screen, then the graphics chip has failed and you will need a new logic board

Check for a failing hard drive
Trying booting from the Mac OS X install disc.
insert the Mac OS X install disc.
press the start button, while holding down the "C" key on the keyboard
Once you are running from the disc. go to Disk Utilities select the hard drive click the "repair permissions" button at the bottom.
If you get any red errors listed or it doesn't seem to finish repairing the permissions you have a failing hard drive and it will need to be replaced.
