At the back of the CRT neck, there is a screw and metal clamp which
keeps the deflection coil (yoke) in position on the tube. You need to
loosen this screw to rotate the deflection coil either direction to
correct the problem. Once you get the picture straightened out,
tighten the screw and you should be good to go.
I had to do this on one of my LIsa systems.
Of course, the usual disclaimers when dealing with CRTs apply. Watch
out for shocks! :)
