(8) Go back to 50% white area to check colour temperature, if out of range, please
go back to step (6).
* 12300ºK
DRI-GW = "DRI-GS" - 7
DRI-BW = "DRI-BS" - 7
Note 1: Apply this adjustment after aging 30 min or more with the beam current
DRI-GC = "DRI-GS" - 7
1700 ± 50µA.
(On the white or green monocolor screen)
DRI-RC = 25
2: The colour temperature is based on the shipment destination as shown in Table 2.1 at
* 17000ºK & 18000ºK
page 20.
DRI-GW = "DRI-GS" - 7
DRI-BW = "DRI-BS" - 7
3: Adjust DRI-GC/GW, DRI-BC/BW , CUT-RW/C and CUT-GW/C as following DATA,
DRI-GC = "DRI-GS" - 5
after finishing DRI-BS and DRI-GS DATA adjustment.
DRI-RC = 27
* 7500ºK
CUT-RW/C = CUT-RS
DRI-GW = "DRI-GS" - 5
CUT-GW/C = CUT-GS
DRI-BW = "DRI-BS" - 5
DRI-RW = 32 (FIXED), DRI-RS = 32 (FIXED)
DRI-GC = "DRI-GS" - 7
DRI-BC = "DRI-BS"
DRI-RC = 25
(For 7500ºK, 12300ºK, 17000ºK and 18000ºK Condition)
Note 1: Use the window pattern of the signal
generator SX-1006 for adjustment.

WHITE BALANCE
(1) The window pattern is received with DVD signal ( component signal).
BACKGROUND
I2C BUS
(2) Apply the adjustment in the same manners as 2 (AV-IN SIGNAL)
However please adjust Y at low bright only to become 0.281 due to the fact that when exiting
service mode, it will drop to 0.275

and subsequence above.
(DVD SIGNAL)
(DRI-GS-DVD, DRI-BS-DVD, CUT-RS-DVD, CUT-GS-DVD)
Apply the adjustment after the end of 2 (AV-IN SIGNAL).
Note: 1. All of the DRI-GW/C-DVD & DRI-BW/C-DVD can be obtain by using same
50% white
calculation as white balance adjustment above (No.2). CUT-RW/C-DVD
Dark white
and CUT-GW/C-DVD setting data are as follow.
CUT-RW/C-DVD = CUT-RS-DVD
CUT-GW/C-DVD = CUT-GS-DVD
DRI-RW-DVD = 32 (FIXED), DRI-RS-DVD = 32 (FIXED)
DRI-BC-DVD = "DRI-BS-DVD"
