ELECTRICAL  ADJUSTMENTS
In making adjustment, refer to 5-2. Adjustment
Related Parts Arrangement.
Note: During diagnostic check, the characters and color bars can
be seen only with the NTSC monitor. Therefore, for diag-
nostic check, use the monitor that supports both NTSC and
PAL modes
This section describes procedures and instructions necessary for
adjusting electrical circuits in this set.
Instruments required:
1) Color monitor TV
2) Oscilloscope 1 or 2 phenomena, band width over 100 MHz,
with delay mode
3) Frequency counter (over 8 digits)
4) Digital voltmeter
5) Standard commander
 * RM-SS300 (1-418-838-11)
6) DVD reference disc
HLX-501 (J-6090-071-A) (dual layer)
HLX-503 (J-6090-069-A) (single layer)
HLX-504 (J-6090-088-A) (single layer)
HLX-505 (J-6090-089-A) (dual layer)
7) SACD reference disc
HLXA-509 (J-6090-090-A)
* Use only the designated remote control when adjusting this
system component.
5-1. ADJUSTMENT  OF  VIDEO  SYSTEM

Adjusting method:
1) In the test mode initial menu “6” Video Level Adjustment, set
so that color bars are generated.
2) Adjust the RV401 to attain 1.0 
± 0.02 Vp-p.

2. S-terminal Output Check (DVD BOARD)
<Purpose>
Check S-terminal video output.  If it is incorrect, pictures will not
be displayed correctly in spite of connection to the TV with a S-
terminal cable.

RE-ADJUSTMENT OF THE SERVO CIRCUIT
The re-adjustment of the servo circuit is necessary
when the part which relates to the servo circuit is
replaced.
Referring to ”4-4. DRIVE AUTO ADJUSTMENT” (see
page 12), Choose ALL and do the re-adjustment of
each item of DVD-SL, CD and DVD-DL.
THE PART THAT THE RE-ADJUSTMENT OF THE
SERVO CIRCUIT IS NECESSARY
1. Optical pick-up
2. RF AMP (IC001)
3. DSP IC (IC701)
4. Motor driver IC (IC801,802)
5. EEPROM (IC201)

3. Checking S Video Output S-C (DVD BOARD)
<Purpose>
This checks whether the S-C satisfies the NTSC Standard.  If it is
not correct, the colors will be too dark or light.
