Checking method:
1) Confirm that each voltage satisfies the specification.
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 diag-
nostic check, use the monitor that supports both NTSC
and PAL modes.
Use the reference disc for PAL for check, and use the ref-
erence 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-D107E/D107P)
6) DVD reference disc
