2.12 Digital convergence adjustment
Note: If replacing a PRT, DY, etc. perform auto-digital
convergence first. (Press front panel MAGIC
FOCUS switch when in normal customer mode).
This can eliminate the need for a complete
digital convergence alignment.
Adjustment preparation
(1) Receive an RF or video signal.
(2) Set controls to factory preset.
(3) Install jig screen on the set.
(4) Note the center of the video pattern displayed.
This is necessary to match dotted lines
(adjustment point viewed) and actual point that
is adjusted and displayed by the video signal.
(5) Press the service only switch (on
POWER/DEFLECTION PWB). The pattern
displayed is now the digital convergence mode.
(6) When performing a complete digital
convergence adjustment CLEAR DATA in RAM.
(With the TV set off, press and hold the service
switch located on the Power/Deflection P.W.B.
and then press the POWER button).
