Just prise off the cover over the external monitor port, remove the outer 2 of the 4 screws now visible, remove the 2 screws by the tilt foot. Lift up the the base from the back, you will feel resistance then hear a cracking noise as it comes away, this is normal. Turn the iMac the right way up. When facing the iMac look down the left side. You will see 2 black plastic adjusters on the side of the flyback transformer. The bottom one is the Screen adjust, the to Focus. Power on the iMac and adjust with an insulated handle screwdriver. Prior to doing that I would look in System Profiler to see what firmware version is installed, it should be ver 4.1.9f. If not You will need OS 9.1, 9.2.1 or 9.2.2 installed to run the firmware updater, available from Apples web site. If the previous owner attempted to install OSX Jaguar they could have created these problems, it's worth checking first before opening up and adjusting. 10.3 Panther warns you when you have old firmware, Jaguar didn't and caused lots of grief. Your older 333 MHz iMac has a completely different insides and boards are not compatible with the slot loaders. Steve Bell -- The iMac List is sponsored by <http://lowendmac.com/> and...
