In making adjustment, refer to 7-4. 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.
Use the reference disc for PAL for check, and use the
reference disc for NTSC for adjustment.
This section describes procedures and instructions necessary for
adjusting electrical circuits in this set.
Instruments required:
1)
Color monitor TV
2)
Single or dual trace oscilloscope, band width over 100 MHz,
with delay mode
3)
Frequency counter (over 8 digits)
4)
Digital voltmeter
5)
Standard commander (RMT-D126A/D126E/D126P)
6)
DVD reference disc
HLX-501 (J-6090-071-A) (dual layer) (NTSC)
HLX-503 (J-6090-069-A) (single layer) (NTSC)
HLX-504 (J-6090-088-A) (single layer) (NTSC)
HLX-505 (J-6090-089-A) (dual layer) (NTSC)
HLX-506 (J-6090-077-A) (single layer) (PAL)
HLX-507 (J-6090-078-A) (dual layer) (PAL)
