overlap with green lines.
6.  Press the “9” button on the remote commander to return to coarse 
adjustment mode.
Note: If lens caps are unavailable, you can cut off the unnecessary color 
beams by controlling the service mode MCP-RON, GON, BON.
3) BLUE ADJUSTMENT

4.  Press the “9” button on the remote commander to enter fi ne 
adjustment mode.
5.  Make the fi ne adjustment so that horizontal lines and vertical lines 
overlap with green and red lines.
6.  Press the “9” button on the remote commander to return `to coarse 
adjustment mode.
Note: When replacing CRTs, adjust the set-up adjustments (2-1 to 2-9) 
and the registration adjustment (2-12). When replacing multiple CRTs at 
the same time, replace and adjust them individually.

4)  REGISTRATION DATA WRITING
1.  After completing each adjustment of green, blue, and red for the 
NTSC Full mode press the “MUTING”+ “ENTER” buttons in PJE 
service mode on the remote commander to write the registration data 
to the NVM.
2-13-2. COPYING ALL REGISTRATION DATA 
TO OTHER MODES
1.  Make sure that the adjustment for NTSC Full mode is complete and 
the data has already been written.
2.  Select the PJE mode.
3.  Select Copy and set the data to “01”, and press the 
“MUTING”+“ENTER” buttons on the remote commander.
4.  The data from the NTSC Full mode is copied to NTSC Zoom Screen, 
HD Full Screen, and HD Zoom Screen modes.

6.  Select the PJE mode.
7.  Select Copy and set the data to “01”, and press the 
“MUTING”+“ENTER” buttons on the remote commander.
8.  The data from the NTSC Wide Zoom mode is copied to 
HD Wide Zoom Screen mode.

9.  Check in the other modes and adjust as demands.
 
Be sure to write data in each mode.
2-14.AUTO REGISTRATION OFFSETS
IMPORTANT
This adjustment must be performed after registration adjustment 
or after readjustment for any reason!
Once registration in all modes is satisfactory:
1.  Darken the room environment near the set.
2.  Select input of RF (with a signal) or Video1 - Video4 (with a signal), 
and enter Full Mode.
 
WARNING: DO NOT USE 1080i SIGNAL!
3.  Enter service mode and select the PJE group.
4.  Press the “MUTING” + “ENTER” buttons on the remote commander 
to write the data for Full mode.
Important:
 
You must complete step 4 even if registration looks OK in Full mode 
and there were not any adjustments made.
5.  To automatically store the offset values, press the “FLASH FOCUS” 
button on the front panel of the set.
 
(The offset value is now stored)
 
If FLASH FOCUS successfully calibrates, it displays
“CALIBRATION OK.” 
If FLASH FOCUS does not successfully calibrate, 
an error message is displayed. (Refer to section 2-15)
6.  Exit the service mode.
7.  If the calibration was successful, press the “FLASH FOCUS” button 
out of service mode.
8.  Confi rm registration is OK in all modes.

2-15.AUTO REGISTRATION ERROR CODES
If an error code is displayed after the set has been correctly adjusted, check the following items: position, tilt and sizing.  If any of these adjustments 
are off, even slightly, the auto-registration pattern will not hit the four sensors properly. This occurs when the internal generator patterns are being 
fl ashed on the screen for the sensors to read.  Therefore, auto registration (called auto convergence) cannot operate properly, causing an error code to 
be displayed. In order for this function to operate properly, position, tilt and size must be adjusted properly.
