White Balance Adjustment Method
Perform the adjustment if the white balance is apparently insufficient.
Note that the total performance will be always degraded because of this adjustment.
White Balance
Adjustment Method
Set the unit to Factory
mode for the function for
which the white balance
seems insufficient.
Use S2801 of the MAIN assy
or the Factory remote control
for projection TV servicing.
Select W/B MODE, then
select and adjust S CON
and SBRI for each color.
To select MODE, press the MUTE key.
For R SCON-1, G SCON-2, B SCON-3, R SBRI-4,
G SBRI-5 and B SBRI-6
Adjustments, use 10-step
picture quality with the signal
generator. Adjust the white
balance so that it becomes
the same in the entire range
from low to high luminance.
(Normally, the initial value
can provide the optimum
result. Note the initial value
so that it can be easily reset.
Exit Factory
mode to finish.
As for SCON and SBRI, they can have three types of memory data, COMP (1,2),
VIDEO, and VIVID that has data relative to the COMP value.
These data are independent to each other, and VIDEO can be adjusted without
affecting COMP. Perform the adjustments independently.
For the VIVID adjustment, see "6.3 Integrator Mode." If the user wants to change
the white balance even when the total balance is sufficient, it is recommended to
adjust it in VIVID mode.
78
Adjust the S CON values so
that they do not exceed 128.
(Essentially, turn down the
stronger colors, using 128 as
a reference value.)
When any S CON value
exceeds 128, the limiter
activates, and the white
balance shown by a gradation
at the peak will become
improper.
Adjustment equivalent to
that with a projection TV is
not possible.
