After replacing the hard drive, the LCD lights but shows nothing.

Disk Utility indicated mechanical failure in the iMac internal hard drive: "back up everything you can." I installed a new hard drive, but when I turn on the iMac I immediately got a solid white screen.

I booted from an OSX install disk, but still got the same solid white screen.

I started it up in FireWire target disk mode, connected to a MacBookPro. Using Disk Utility on the MacBookPro, I was able to eject the OSX install disk from the iMac. I was also able to successfully install OSX Snow Leopard on the new hard drive in the iMac. But even in target disk mode, the iMac screen remains white - no blue screen with yellow target disk icon.

Now the iMac boots up fine, I hear the "Welcome to OSX" music (doot doot da do-do) but the screen is solid white.

I reset the parameter RAM 7 or 8 times. I've checked all cables inside the iMac. I booted up in safe mode and verbose mode. Always the same result - everything works, but nothing appears on the iMac screen - no spinning startup wheel, no question mark, no text in safe mode. The display lights up, but nothing appears on it.

Unplug all peripherals, unplug the machine, press and hold the power button for 10 seconds. Plug it back in and give it a try. If this fails, plug it into an external monitor to try to isolate the problem.

Unplugging everything and following the above steps: no change.

However, I finally obtained a MiniDVI to VGA adapter, and the remote monitor works fine.

The main screen is still solid light gray all the time...

I appreciate your help!
