2. When the probe
of oscilloscope is connected,
disconnect it.
3. Press the TEST button
on the remote control.
4. Press
the WB-HIGH button on it.
5. By using the color analyzer, adjust DAC values of (R)
and (8) at WB-HIGH mode so that white chromaticity
coordinates on the screen
may be "x,.O.3180 and
y=O.3540.
However, adjustment of DAC value of (G) is not
required.
6.
Press the WB-LOW
button
on it.
7. Adjust
each DAC value
at WB-LOW
mode to the
following values.
R = 155
G " 128
B = 225
8. Press the WB-HIGH button on it.
9. Press

buttons on the remote
controller
in the order
as shown
in Fig. 29 below.

15. Make
sure whether or not B cathode
voltage levet
exceeds 140Vp-p.
16. If 11 exceeds 140Vp-p, adjust i1 to the said value
by
using R3729 (SUB CONTRAST).
