SECTION 1
SELF DIAGNOSIS FUNCTION
The unit in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED will automatically begin to
flash.
The number of times the LED flashes translates to a probable source of the problem. A definition of the STANDBY/TIMER LED flash
indicators is listed in the instruction manual for the user's knowledge and reference. If an error symptom cannot be reproduced, the remote
commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems
occur.
1-1. DIAGNOSTIC TEST INDICATORS
When an error occurs, the STANDBY/TIMER LED will flash a set number of times to indicate the possible cause of the problem. If there
is more than one error, the LED will identify the first of the problem areas.
Result for all of the following diagnostic items are displayed on screen. If the screen displays a “0”, no error has occurred.
* If a +B overcurrent is detected, stoppage of the vertical detection is detected simultaneously. The symptom that is diagnosed
first by the microcontroller is displayed on the screen.
** Refer to screen (G2) adjustment (fine adjustment) in section 2 of this manual.
*** Is STNDBY/TIMER LED flashes six (6) times, unplug the unit and wait 10 seconds before performing the adjustment.

1-4. SELF-DIAGNOSTIC SCREEN DISPLAY
For errors with symptoms such as “power sometimes shuts off”or “screen sometimes goes out”that cannot be confirmed, it is possible to
bring up past occurrences of failure for confirmation on the screen:
[To Bring Up Screen Test]
In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:
Self-Diagnosis screen display
1-5. HANDLING OF SELF-DIAGNOSTIC SCREEN DISPLAY
Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen.
After you have completed the repairs, clear the result display to “0”.
[Clearing the result display]
To clear the result display to “0”, press button on the remote commander sequentially as shown below when the diagnostic screen is being
displayed.
[Quitting Self-diagnostic screen]
To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.
Press “8”button
(It will indicate “CLEAR”on the screen.)
Press “-”button
(The “CLEAR”display change to red color.)

+B overcurrent (OCP) Occurs when excessive current flows through R6812.
The increase in voltage across Q6803 causes it to turn on which sends a high
signal to the micro.
+B overvoltage (OVP) IC6801 detects +B OVP condition and Q6802.
This sends a high signal to the micro and also shuts down the AC relay.
V-STOP Occurs when an absence of the vertical deflection pulse is detected by pin 56 of
IC0404 (MG board)
Power supply will shut down when waveform interval exceeds 2 seconds.
White balance failure If the RGB levels* do not balance within 2 seconds after the power is turned on,
this error will be detected by IC0401.
TV will stay on, but there will be no picture.
Low +B OCP/OVP Occurs when set 5V is out.
Horizontal deflection stopped Occurs when either :
1) a +B overcurrent is detected (Q6803), or
2) IC0401 (MG board) is damaged.

2. Receive video dot hatch pattern.
3. Use lens-cover to red and blue.
4. Adjust electric focus. (roughly)
5. Rotate the green lens and adjust to obtain the best lens focus.
6. Rotate the green focus volume on the focus pack and adjust to
obtain best electrical focus.
7. If focus is not good, repeat 4 process.
8. Repeat above process for red and blue lenses and electric fo-
cus.
9. Fix lens screw.
3-4. DEFLECTION YOKE TILT ADJUSTMENT

same as was done for green.
SECTION 3
SET-UP ADJUSTMENTS
3-1. SCREEN VOLTAGE ADJUSTMENT
(ROUGH ALIGNMENT)
1. Receive the Monoscope signal.
2. Set 50% BRIGHTNESS and minimum PICTURE.
3. Turn the red VR on the focus pack all the way to the left and
then gradually turn it to the right until the point where you can
see the retrace line.
4. Next gradually turn it to the left to the position where the
retrace line disappears.
3-2. SCREEN (G2) ADJUSTMENT
(FINE ADJUSTMENT)

(Fig.3-2)
3. Turn red of G2 VR clockwise, then retrace line appear.
4. Turn G2 VR counterclockwise and set retrace line just
disappear.(Fig.3-3)
5. Add DC voltage DC (174 ±0.5V) to KR.
6. Confirm if retrace can be seen.
7. Adjust green and blue at the same method.

2. Set “Hi Fine” and PICTURE 100%, other 50% and white
balance “COOL”. (VM OFF)
3. Blue 4 pole : make round in the center of screen.
4. Confirm that center dot focus is adjusted in focus. (Fig.3-12a)
5. Adjust blue electrical focus to make the left side spot nearly
round by minimizing width and height. (Slight overfocus is
OK) (Fig.3-12b)
6. Confirm that the green to blue spot size is within spec.
Blue center dot height shall be ≤1.2 times the green dot heght.
7. Return making condition data to orignal data.
3-7. GREEN, RED AND BLUE FOCUS
ADJUSTMENT
3-7-1. Green, Red and Blue lens focus adjustment
1. Input a cross hatch signal into VIDEO 1. (composite video
input)
2. Place a lens cover over red and blue lenses and project only
green.
3. Rotate the green lens and adjust to obtain the best lens focus at
the center area.
4. Fix lens screw.
5. Repeat above process for red and blue.
3-7-2. Green and Red electrical focus adjustment
1. Input a cross-hatch signal into VIDEO 1.
2. Project only Green.
3. Rotate the green focus volume on the focus pack and adjust to
obtain the best focus at the center screen.
4. Repeat above process for red.
3-5. 2-POLE AND 4-POLE MAGNET
ADJUSTMENT
3-5-1. Adjustment of 2-pole magnets
1. Receive the Dot signal (1080i/50Hz) from HD/DVD 1 termi-
nal.
2. Place the caps on the red and blue lens so that only the green
color is shown.
3. Turn the green focus volume of focus pack counter-clock-
wise, so that diameter of the dot become large.
4. Adjust the 2-pole magnet, counter-clockwise and clockwise
center of the dot doesn't move. (Use focus volume)
5. Center position is changed by 2-pole magnet adjustment.
So, center magnet adjustment and 2-pole magnet adjustment
are needed tracking adjustment.
6. Repeat same adjustment method for red and blue.
3-5-2. Green, Red, Blue adjustment of 4-pole
magnets
