ABSTRACT:
A deflection yoke adjustment apparatus for adjusting a yoke on a kinescope comprises independent coil holders for supporting the horizontal and vertical deflection coils of the yoke. Six elongated positioning rods are attached to particular locations on each coil holder. Actuators, for example stepping motors, move selected ones of the rods to cause translation of the coil holders along a vertical, horizontal or longitudinal axis, or rotation of the coil holder about any of the aforementioned axes. The vertical and horizontal coils may be moved independently to provide an optimum kinescope display. The apparatus also comprises coil alignment devices associated with each positioning rod to maintain coil orientation during movement and force limiting means to protect the kinescope against damage during coil movement.
