Automatic Adjustment Results Display Function (Self-Check Function)
On the unit (SL-SV590), each automatic adjustment result are displayed on the remote control display. This function is convenient
to check or identify which automatic adjustment circuit is incorrect.
The followings are the contents of the automatic adjustment result displays (Self-Check Function).
8.1.1.
How to display automatic adjustment results
1. Load the test disc (SZZP1054C).
2. Press the
(SKIP/SEARCH) and
(SKIP/
SEARCH) buttons simultaneously and hold them, and
additionally press the
(PLAY/PAUSE) button.
3. Press the
(STOP/TURN OFF) button once.
4. An automatic adjustment result is displayed on the
remote control display.
8.1.2.
Display of automatic adjustment results (Self-Check Function)
<Example>
Follow the below steps when E1 is displayed.
(Cause: Focus balance (FBC) is set beyond the limit.)
• Check if
1. the waveform or voltage of the focus servo circuit is
correct, and
2. the optical pick-up returns to the normal state by
exchanging the traverse deck.
Follow the below steps when E4 is displayed.
(Cause: Focus gain (FGC) is set beyond the limit.)
• Check if
1. the waveform or voltage of the focus servo circuit is
correct,
2. the focus coil of the optical pick-up is correct (around
8 ohms), and
3. the optical pick-up returns to the normal state by
exchanging the traverse deck.
Follow the below steps when EF is displayed.
(Cause: All adjustments (TGC, FGC, TBC, FBC) are set
beyond the limit.)
• Check if
1. the optical pick-up returns to the normal state by
exchanging the traverse deck, and
2. the waveform or voltage of the servo ICs are correct.
Note:
It is not always necessary to exchange the traverse deck
when an error message is displayed.
Be sure to check if the circuit is defective or not before
exchanging the traverse deck.
Note:
If any other disc than the test disc (SZZP1054C) is used, an
error message may be displayed.
This is not a malfunction.
