SYMPTOM No or poor east/west correction.
CAUSE
Various components.
ACTION
Before replacing any components for no or poor east/west correction, check that the
waveform  on  the  east/west  control  pin  of  IC201  (pin  45)  is  changing  when  the
geometry setting is adjusted in the service mode.  The waveform on this pin will be a
parabola at vertical rate.
If the waveform does not change, or changes by only a small amount, it is likely that
either the NVM (IC104) or the VDP (IC201) is faulty.
If the waveform does change, then the fault is likely to be in the region of either the
drive or output circuit.  R519 (100k, 05.W) has been known to go open circuit.
