     If none of the knob/shaft controls you can reach will not do the job,
the fix may require removing the case. If you do this, be careful: WEAR
GOGGLES. Work on a plastic or wooden table with ample space. Avoid
touching metal contacts, circuit points, the back of the CRT, etc.. Do not
stress the CRT's neck!

     Once the back is off, have the monitor placed so that it is not about
to tump over. Have a mirror placed so you can see the screen when you make
adjustments. 

     Some monitors allow adjusting position via mini-switches near the
back of the circuit board. You can try moving these using a plastic rod.
(Perhaps a mini-switch is making poor contact in the correct position and
needs to be diddled.)

     Some monitors allow adjusting display position via metal tabs on flat
rings around the CRT neck. Whenever you get anywhere near the neck of the
CRT,  be careful. You do NOT want to bonk it with some heavy metal tool
(like a screwdriver).  You do not want to get popped by an arc from the
High Voltage power supply or the fat Anode lead that plugs into the back
of the CRT and bump the CRT neck.

    (There may be some other way to adjust display position on the Apple
Green Monitor. If so, perhaps someone who has adjusted this particular
monitor will post a message here.)
