Checking method:
1) Confirm that each voltage satisfies the specification.

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.

1) Color monitor TV
2) Oscilloscope 1 or 2 phenomena, band width over 100 MHz,
