ADJUSTING THE PC INTERFACE (CPCi-0054CE01/02. PC I/F Unit)
1.The initialization of the set.
1) Press the S2601 switch to go to the process mode.
2) Perform S1 of the SSS menu. (S1 initializes only a PC I/F board. Don’t perform S2 because adjustment data
2) Perform S1 of the SSS menu. (S1 initializes only a PC I/F board. Don’t perform S2 because adjustment data
except for the PC board are initialized.
3) Make sure that version of the SPECIAL program (VER.XXX) of the menu is the latest.
2.Adjusting the level.
2-1. Setting the oscilloscope
2-1. Setting the oscilloscope
Set the range to DC 1 V/div and 5
µ
/div.
2-2. Connecting the PC Interface
1) Connect the cable between the ANALOG OUTPUT (PC computer) and the DSUB connector (INPUT1 of the
proejctor).
2) Set the PC computer in the XGA mode (1024 x 768, 60 Hz, 32-step scale). Adjust the output amplitude to 700
mVp-p (terminated with 75 ohms) for the black-to-white portions.
3) Turn on the power.
2-3. Adjusting and checking the level
1) Press the S2601 switch to go to the process mode.
2) Set the SH-PHASE on the OUTPUT3 menu to 8. (Make the characters on screen clear and crisp.)
3) Adjust black level of red signal with R-BRIGHT of the A/D in a place to become bit less condition.
4) Adjust black level of blue signal with B-BRIGHT of the A/D in a place to become bit less condition.
5) Adjust black level of green signal with G-BRIGHT of the A/D in a place to become bit less condition.
2) Set the SH-PHASE on the OUTPUT3 menu to 8. (Make the characters on screen clear and crisp.)
3) Adjust black level of red signal with R-BRIGHT of the A/D in a place to become bit less condition.
4) Adjust black level of blue signal with B-BRIGHT of the A/D in a place to become bit less condition.
5) Adjust black level of green signal with G-BRIGHT of the A/D in a place to become bit less condition.
2-4. Adjusting the DTV
1) Set the switch to the BNC input terminal of INPUT1
2) Set up a signal generator in 1080i 60Hz mode white signal.Output amplitude makes space between black - white
2) Set up a signal generator in 1080i 60Hz mode white signal.Output amplitude makes space between black - white
700mVp-p (75ohm terminated) .
3) Connect the analog output terminal of the signal generator and BNC connector (the INPUT1 terminal of projector)
with the cable.
4) Make G-BRIGHT of DTV the numerical value which is the same as G-BRIGHT of A/D.
5) Set up the level of the signal output in 53%, and adjust with CB-OFFSET of the DTV in a place to become bit less
5) Set up the level of the signal output in 53%, and adjust with CB-OFFSET of the DTV in a place to become bit less
condition.
6) Set up the level of the signal output in 53%, and adjust with CR-OFFSET of the DTV in a place to become bit less
condition.
7) After adjusting the CB-OFFSET and CR-OFFSET, 6 point adds G-BRIGHT.
8) Press the S2601, to comes out of the process mode.
8) Press the S2601, to comes out of the process mode.
Servicing precautions
(1)If the convergence gets out of spec in servicing the set, call the process mode and select the following group and
subjects.
Group: NOKO
Subject: R-CNV-H, R-CNV-V
Group: NOKO
Subject: R-CNV-H, R-CNV-V
G-CNV-H, G-CNV-V
B-CNV-H, B-CNV-V
B-CNV-H, B-CNV-V
(H and V are for horizontal and vertical adjustments, respectively.)
Adjust the above settings to the range of 0 to 4.
Adjust the above settings to the range of 0 to 4.
(2) When entering the process mode, select the following group and subjects too.
Group: VIDEO1
Subject: SET-UP B
Subject: SET-UP B
SET-UP C
Make sure the SET-UP B and SET-UP C settings are 10 and 2, respectively. To exit from the process mode,
be sure to take either of the following ways: Go to the subject SET-UP 1 and quit the mode, or select Group:
SSS and Subject: S4 and quit the mode.
