(R/C, Service
mode V113) 1. Connect the oscilloscope probe between TP1801
and GND.
2. In the twin-picture mode, receive the NTSC stand-
ard half color bar signal for the left-side screen (Main
Screen).
3. Using the VOLUME UP/DOWN keys in the Service
mode V113, adjust the waveform amplitude of the
main luminance signal at TP1801 to 0.5±0.05 Vp-p.
Note: The amplitude must be measured from the
black level to the white peak.
