| Comments on vertical prob.. >>
This usually indicates a fault in the vertical output circuit. If it uses
an IC for this, then the chip could be bad. It could also be a bad capacitor
or other component in this circuit. It is probably caused by a fault in
the flyback portion of the vertical deflection circuit - a charge pump that
generates a high voltage spike to return the beam to the top of the screen.
Test components in the vertical output stage or substitute for good ones.
