SECTION 7
ELECTRICAL ADJUSTMENT
DVP-NS705V/NS755V/NS905V/NS915V
In making adjustment, refer to 7-6. 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 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 (RMT-D146P/D147A/D147E/D1470/
D147P)
6) DVD reference disc
