SELF DIAGNOSTIC FUNCTION

The units in this manual contain a self diagnostic function. If an error occurs, the STANDBY (Power) indicator will automatically begin to flash. A description of the self-diagnosis function is explained in the instruction manual. The number of times the STANDBY (Power) indicator flashes translates to a probable source of the problem. 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.

DIAGNOSTIC TEST INDICATORS

When an errors occurs, the STANDBY (1) indicator will flash a set number of times to indicate the possible cause of the problem. If there is more than one error, the indicator will identify the first of the problem areas.
Result for all of the following diagnosis items are displayed on screen. No error has occurred if the screen displays a "0".

If a +B over current is detected, stoppage of the vertical deflection is detected simultaneously. The symptom that is diagnosed first by the mirco controller is displayed on the screen.

+B over current [OCP] > Occurs when an over current on the +B(135V) line is detected by pin 32 of IC001 (A board).  If the voltage of pin 32 of IC001 (A board) is more than 4V, the unit will automatically go to standby.

V-PROTECT > Occurs when an absence of the vertical deflection pulse is detected by pin 13 of IC001 (A board)

IK [AKB] > If the RGB levels* do not balance within 15 sec after the power is turned on, this error will be detected by IC001 (A board). TV will stay on, but there will be 5 times LED blinking.

POWER SUPPLY NG (+5V) for VIDEO PROCESSOR > Occurs when IC001 internal HV protect detects an abnormal H-Pulse (frequency) due to improper power supply to IC001. TV cuts off high voltage power of anode CRT. No picture will be detected. eg: IC602, IC604 go faulty.

STOPPING THE STANDBY (Power) INDICATOR FLASH
Turn off the power switch on the TV main unit or unplug the power cord from the outlet to stop the STANDBY (Power) indicator from flashing.

SELF-DIAGNOSTIC SCREEN DISPLAY
For errors with symptoms such as "power sometimes shuts off" or "screen sometimes goes off" that cannot be confirmed, it is possible to bring up past occurrences of failure on the screen for confirmation.

To Bring Up Screen Test
In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:

Display / Channel 5 / Volume(-) / Power / TV.  [Note that this differs from entering the service mode (volume [+]).]

Numeral "0" means that no fault was detected.
Numeral "1" means the number of a fault occurrence (1 ~ 255)

HANDLING OF SELF-DIAGNOSTIC SCREEN DISPLAY
Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen during repairs. When you have completed the repairs, clear the result display to "0".
Unless the result display is cleared to "0", the self-diagnosis function will not be able to detect subsequent faults after completion of the repairs.

Clearing the result display
To clear the result display to "0", press buttons on the remote commander subsequent as shown below when the self-diagnostic screen is being displayed.

[ 8 => 0 ]

Quitting Self-diagnostic screen
To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.

FOCUS ADJUSTMENT
FOCUS adjustment should be completed before the W/B adjustment:
1. Receive digital monoscope pattern.
2. Set picture mode: DYNAMIC.
3. Adjust focus VR to obtain a just focus at the center of the screen.
4. Change receiving signal to white pattern and blue back.
5. Confirm MAGENTA RING is not noticeable. Incase magenta ring is obvious, then adjust FOCUS VR to balance magenta ring and FOCUS.

G2 (SCREEN) ADJUSTMENTS
1. Set the PICTURE & BRIGHTNESS to STANDARD.
2. Put the Video input mode signal.
3. Connect R,G,B of the C board cathode to oscilloscope.
4. Adjust Brightness to obtain the cathode value to value below.
5. Adjust G2 (screen) on the FBT until picture shows the point before cut off.

WHITE BALANCE ADJUSTMENT
1. Set to Service Mode
ADJUSTMENTS WITH COMMANDER)
2. Input white raster signal.
3. Set Picture to <DYNAMIC mode>
4. Select RDRV (02) with 1 and 4 and fixed the value to 25 with 3 and 6.
5. Adjust WHBL GDRV (03) and BDRV (04) with 1 and 4 and adjust the data with 3 and 6 for best white balance in Highlight condition.
6. Write into the memory by pressing [MUTING] then [0].
7. Adjust WHBL BKOR (00) and BKOG (01) with 1 and 4 and adjust the level with 3 and 6 for best white balance cut-off condition.
8. Write into memory by pressing [MUTING] then [0].
9. US model need to apply only for colour temperature in Neutral.

SUB BRIGHT ADJUSTMENT
1. Set to service mode.
2. Brightness set to 50%, Picture....Minimum
3. Select WHBL SBRT (10) with 1 and 4 and adjust SBRT (10) data with 3 and 6 so that the third stripe from right dimly lit.
4. Write into the memory by pressing [MUTING] then [0]-.
5. GA models C/O: 20 IRE S/G: 30 IRE

Service adjustments to this model can be performed using the supplied remote commander RM-W101 and RM-W150.
