I'm not sure what you mean by "scattered".

Does the IIgs monitor have a horizontal position control?  It sounds
like it does, and if by "scattered" you mean that it is jumping
back and forth, then that control may be noisy and need cleaning with
potentiometer cleaning fluid.

Position controls for magnetic deflection monitors are low-resistance
units, often wire-wound, and are prone to developing electrical "noise"
due to the accumulation of dust and other contaminants between the
winding/element and the wiper.  Cleaning usually does the trick.

If the raster is tilted ("leans"?) instead of simply horizontally
displaced, then the yoke has been twisted on the neck of the CRT and
will need to be readjusted after opening the case.

Some monitors (not sure about the IIgs RGB monitor) have horizontal
and vertical positioning magnets near the yoke that can be adjusted.
