ELECTRICAL ADJUSTMENT
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
diagnostic 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-SS800 (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
