Focus on Gateway Vivitron 1100 21" monitor

[Andrew]

Have a GW Vivitron 1100 21" monitor (mitsubishi?) that's been in storage
for about 12 mths. Worked fine going in. Now its focus(?) is poor to the
point of being unuseable. Colour, brightness, contrast, position adjustment
all work fine. The image is just very fuzzy. No external focus adjustment
obvious. Tried different different resolutions, colour depth, other high
quality cables, powerpoints, different pc's, reloaded drivers all without
sucess.

Anyone suggest what might cause this, and how I might correct it. Cannot
find a schematic or anyone local (Tampa FL) able to service it it seems.

thanks

seems unlikely but easy to check, look at the defection yoke
and focus magnets. maybe it got slammed going into or out
of storage, or the environment in storage caused some adhesive
to fail? good luck, --Loren
