[FINAL CHECK]
1. Store the new adjustment (offset) value on the remote control
by pressing [MUTING] and [ENTER].
2. Press the FLASH FOCUS button on the front panel.
(The Offset value is now automatically stored.)
3. Check that no error message appears.
If an error message appears, recheck.
Note : In case of replacing CRTs, adjust the set-up adjustments
(items 3-1 to 3-8) and the registration adjustment (item 3-10).
In case of replacing two or three CRTs at the same time,
replace and adjust one by one.

CODE
[ERROR CODE LIST]
If an error code is displayed after the set has been fully adjusted, correctly, please check the following items: position, tilt and sizing.  If
either 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 is being flashed on the screen for the sensors to read.  Therefore, auto registration (called auto-focus) cannot
operate properly causing an error code to be displayed. In order for this function to operate properly, correct position, tilt and size must be
adjusted properly.

that the hold-down circuit operates at a static voltmeter read-
ing of 31.0 
±
 0.5kV dc when the raster disappears.

1. REPART STEPS 1 ~ 5 as above.
2. Just at the point hold-down circuit begins to operate switch
off the set.
3. Remove the VR connected across CN8008, and measure it’s
resistance.
4. Solder a resistor value, nearest to the measured value, across
CN8008.
5. Reconfirm operation check.
4-3. +B MAX VOLTAGE CONFIRMATION
The following adjustments should always be performed
when replacing IC6101.
1. Supply 120.0 
±
 2.0VAC  to variable autotransformer.
2. Receive dot signal pattern and set the PICTURE and
BRIGHTNESS settings to their minimum.
3. Confirm the voltage of TP  +B 135V is less than 137.0Vdc.
4. If step 4 not satisfied , replace IC6101 and repeat above steps.
[ G BOARD]
4-4. +B OVP CONFIRMATION
1. Connect a voltmeter to TP. OVP and ground.
2. Supply 120VAC to variable autotransformer.
