XV-Z9000U/E
1. Initializing the EEPROM
1) Press SW2002 to enter the process mode.
2) Execute the S1 command on the SSS menu. (The S1 command initializes the PC board alone. Do not
execute the S2 command because otherwise the adjustment data other than the PC board will be initialized.)
3) Make sure that the program version VER.XXX on the SPECIAL menu is the latest one.
2. Adjusting the levels
2.1 Setting the oscilloscope
Set the oscilloscope range to DC 1V/div. and 5 µsec/div.
2.2 Connecting the PC interface
1) Connect the specified cable between the analog output jack (signal generator) and the DUSB connector
(INPUT5 of the projector). Set the projector's input selector to INPUT5.
2) Set the signal generator to the XGA mode (1024x768, 60 Hz, 32 tones). Adjust the output amplitude to 700
mVp-p between the black and white levels (terminated with a 75-ohm impedance).
3) Turn on the power.
2.3 Adjusting and checking the levels
1) Press SW2002 to enter the process mode.
2) Adjust the R-BRIGHT setting of Group A/D until bit dropouts start at the black level of the red signal.
3) Adjust the B-BRIGHT setting of Group A/D until bit dropouts start at the black level of the blue signal.
4) Adjust the G-BRIGHT setting of Group A/D until bit dropouts start at the black level of the green signal.
2.4 Adjusting the DTV
1) Feed the signal to the INPUT2's RCA input terminal.
2) Set the signal generator to the 1080i 60-Hz mode with white signal. Adjust the output amplitude to 700 mVp-
p between the black and white levels.
3) Connect the specified cable between the analog output (signal generator) and the RCA connector (INPUT2
of the projector).
4) Make the G-BRIGHT setting the same as the G-BRIGHT setting of Group A/D.
5) Adjust the CB-OFFSET setting of Group DTV to 20.
6) Adjust the CR-OFFSET setting of Group DTV to 20.
7) When the CB-OFFSET and CR-OFFSET settings have been made, add 5 points to the G-BRIGHT setting for
Model XV-Z9000U and 4 points for Model XV-Z9000E.
8) Finally press SW2002 to exit from the process mode.
