The SMs for the earlier -- & higher end -- Apple monitors (like the 13" RGB,
Macintosh Color Display, etc.) tend to have fairly elaborate instructions on
take-apart, adjustments to inside pots, etc. -- everything but a circuit
schematic. The Performa Plus display SM, however, has much the same wording
as the 14" Color Plus 1: if it's broke, send it back. (The Performa Plus is,
apparently, the same tube in a slightly different-looking housing.)
I found a Color Plus Monitor in alley once, & fiddled with the color
adjustments to amke it look good before I donated it. If you open up the
housing (usual precautions apply, no responsibility here assumed for damage
to monitor or self, etc...) & look at the main board from the back, I seem
to recall that there is a row of plastic pots (potentiomenters) across the
back (or is it the side? -- I may be confusing it with the Mac Color
Display).
If I remember correctly, there are even icons molded into the plastic in the
back showing you what the various pots do (pincushion, convergence, etc.) Or
there may be lettering, I'm not clear which monitor I'm thinking of now, but
anyway, these pots are the kind you can use a (small) metal screwdriver to
turn (I think). I'm pretty sure there is 1 for horizontal size.
BTW, I seem to recall that there was a trick to opening the housing -- there
are 2 (?) screws on the bottom, & (maybe) 2 on the side, but with the top
you have to press down with your thumbs just behind the edge between the
front bezel & the back housing that you're removing, an inch or 2 from the
sides of the monitor, until some kind of catch on the interior plastic
releases.
Good luck.
