convergence first. (Press front panel MAGIC
FOCUS switch when in normal customer mode).
This can eliminate the need for a complete digi-
tal convergence alignment.
Adjustment preparation

(2) Set controls to factory preset.

ment point viewed) and actual point that is
adjusted and displayed by the video signal.
(5) Press the service
POWER/DEFLECTION PWB). The pattern dis-
played is now the digital convergence mode.
(6) When performing a complete digital conver-
gence adjustment CLEAR DATA in RAM. (With
