[ W/B-adjustment procedures ]
The W/B adjustment can be performed with the RS232C commands with the Media Receiver not connected to this unit. The GGF1475
special communication tool and a Minolta CA-100 color difference meter are required.
1
Enter Operation-without-the-Media-Receiver mode with the "SCN" RS232C command.
2
Set the keyword for the DIGITAL VIDEO Assy to "not adjusted" with the "UAJ" RS232C command.
3
Obtain the current adjustment values in the two adjustment tables (see "6.3.1 RS232C commands").
• Shifting to Table 1: Send the "M51" and "F60" commands. Obtaining the adjustment values: Send the "GPW" command.
• Shifting to Table 2: Send the "M51" and "F75" commands. Obtaining the adjustment values: Send the "GPW" command.
4
Make settings for various functions.
Send the "PPN," "SDN," "SPN," and "WAY" commands.
Note:
After adjustment, when the POWER switch is set to OFF, these settings will be reset to the initial values.
5
For each table, set the brightness.
• Adjustment in Table 1: After sending the "F60" command, perform adjustment.
• Adjustment in Table 2: After sending the "F75" command, perform adjustment.
For each table, change the RGB parameters so that the values measured using a Minolta color difference meter (CA-100)
become as indicated below. In this case, any one of PRH, PGH, or PBH must be set to 256.
6
Check after adjustment
• Shifting to Table 1: Send the "F60" command. Obtaining the adjustment values: Send the "GPW" command.
• Shifting to Table 2: Send the "F75" command. Obtaining the adjustment values: Send the "GPW" command.
Check that the adjustment data have been changed.
7
Change the keyword for the DIGITAL VIDEO Assy to "adjusted" by sending the "FAJ" RS232C command.
Note:
Use a Minolta CA-100 color difference meter or the equivalent for measurement. Otherwise, the specifications of the product cannot be
assured.
Note:
To cancel adjusted data and return to the values before adjustment, send the "BCP" RS232C command. Turn the AC
power off then turn it back on before setting the unit to Standby OFF. The backup values are then retrieved.
If the white balance (W/B) value is largely shifted because of aging, etc., W/B adjustment is required. (As this may be a rare
case, the adjustment procedures are described below, just for your reference.)

[Clearing the data in the ROM of the DIGITAL VIDEO Assy]
After either YES or NO is selected on the display shown above, the indication shown below is automatically displayed. Move the cursor to
YES then press the Enter key. The data in the ROM of the DIGITAL VIDEO Assy become those for a service part (not adjusted).
Notes:
• Use this operation after the DIGITAL VIDEO Assy in failure is repaired and is to be reused as a service part.
• In normal replacement of the Assy with a new service part, this operation is not required. Select NO after replacement with a
service part.
