I have an Eizo F55S monitor and the image is not very sharp. I guess it
is a low contrast problem. I have adjusted the contrast to 100%, but
this does not eliminate the problem. Are there any internal switches
that could help?

I have read the monitor repair FAQ and it says that some monitors have
a hole that permits adjustment with a screwdriver without actually
opening the monitor. Could that be done with this monitor? Is there any
way to get a sharp image (vivid colors, etc.) out of an aged monitor?

Your monitor might just be a tad out of focus. If that is the case, adjusting
the contrast won't have any effect on the focus.
Check to see if it has a focus adjustment control somewhere on the rear or side
of the monitor. If you can find it, tweak it just a little and see if it makes
a difference. If it does, continue adjusting until the image is sharply in
focus.
If it doesn't have any effect, or doesn't bring the display into sharp focus,
your monitor might have a problem in the high voltage area. At this point, it's
probably best to take it to a shop that can repair monitors, or junk it and buy
a new monitor.

Any idea how many hours are on the monitor? After several years of heavy
use the tubes do go soft and you get the results you describe. At that
point the monitor has reached end of life.

You can try adjusting the focus control. This is usually located on
the high voltage multiplier, or on the CRT curcuit board.

In aged monitors, poor focus is normaly caused by the CRT going weak
from age. On some occasions, a defect in the high voltage multiplier
can cause poor focus.

Thanks everyone who offered to help.

I think the problem is not the focus as there is no image blurring, but
the contrast/colors. Anyway, i found 2 holes on the left side of the
monitor, does anyone know what they are used for?

Probably focus 1 and focus 2, could be focus and G2 (master brightness).
You can try tweaking them, just remember where they were. Sounds like
the monitor is probably shot though.
