You usually have red and blue wires to the H coils. The "pin" ckt is usually on
the blue one. Through a coil or some other stuff you'll get to a transistor or
fet that should have either vertical parabola fed to the base, or Hrate PWM
modulated by the vertical parabola.

Ninety nine percent of the time, if the picture is too narrow something is
open, if too wide shorted. This does not apply to the capacitors in the ckt. It
mainly applies to the semiconductors, the pin modulator or the bottom diode. As
far as the caps go, you'll have to check them if the ohmmeter doesn't prove
anything.
