DVP-NC615/NC655P
In making adjustment, refer to 7-3. 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.
Use the reference disc for PAL for check, and use the refer-ence
disc for NTSC for adjustment.
This section describes procedures and instructions necessary for
adjusting electrical circuits in this unit.
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)
