Drive Auto Adjustment - Sony DVP-C600D Service Manual

6-5. Drive Auto Adjustment

The drive can be automatically adjusted, except disc change and
tangential skew adjustment. For a disc, use the disc for adjust-
ment.
In case of abnormality, press the [STOP] key to stop adjustment.
If the drive does not stop, prevent secondary failure by taking
proper action such as disconnection of the power cable. This ad-
justment should be made after repair is finished and no trouble is
present in the drive.
A trouble, if present, causes NG and the adjustment to be aborted.
As the secondary failure could occur, perform automatic adjust-
ment after the drive is completely repaired.
With the initial menu displayed, press [1] on standard commander,
and the screen as shown in Figure 8 will appear.

The tray opens after the [ENTER] key is pressed and the initial-
ization is finished. Then, place the disc for adjustment. If "ALL"
is selected, place three discs, DVD_SL, CD and DVD_DL for ad-
justment. Press the [ENTER] key to start adjustment. During ad-
justment, the tangential skew adjustment screen is displayed. Make
this adjustment only when the pickup was replaced.
As for adjustment, rotate the T-SKEW adjusting screw on the
pickup so that the displayed jitter becomes minimum (CCW makes
jitter smaller). Avoid extreme rotation or interference of screw-
driver with the disc. After all of the adjustments are finished, turn
off the power and unplug. Then apply a drop of locking agent to
the recess of screw.
Note that if "All" is selected, the data of previous adjustment are
erased and initial values are set.
