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
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-D108A/D109A/D111A/D111E)
6) DVD reference disc
HLX-501 (J-6090-071-A) (dual layer)
HLX-503 (J-6090-069-A) (single layer)
