I just purchased a used Snow CRT iMac (Summer 2001), and the screen is
blurry in the center (but sharp on the edges). It's also fairly dark,
even with the brightness all the way up.
I'dbe very surprised if there isn't a focus adjustment knob somewhere inside, just like on a TV set. Question is, where? Are there any websites that would show that kind of info?

The Focus and Screen (for brightness adjustment) are easy to access. Turn
the iMac upside down. 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.
Thank you Steve, that's exactly what I was hoping for. I'll give it a try on my next day off! The firmware is current - I looked at that first before I wiped the drive and installed fresh copies of OS 9.2.2 and Panther.
