How to enter Service Mode
Service adjustments to this model can be performed using the supplied remote Commander RM-ED009.
1. Turn on the power to the TV set and enter into the stand-by mode.
2. Press the following sequence of buttons on the Remote Commander.
ON SCREEN DISPLAY (i) > CHANNEL 5 > VOLUME + > POWER ON
3. The menu will then appear on the screen.
4. Move to the relevant command using the up or down arrow Mbuttons on the remote commander.
5. Press the right arrow button to enter into the required menu item.
6. Press the ‘Menu’ button on the remote commander to quit the Service Mode when all adjustments have been completed.
Note : After carrying out the service adjustments, to prevent the customer accessing the ‘Service Menu’ switch the TV set OFF and then ON
Gamma Adjustment
The following adjustments are done via ECS.
Note: Before Gamma adjustment can begin the set needs 20 minutes aging with an ambient temperature between 22 to 28 degrees centigrade.
Preparation before Gamma Adjustment
1. Set SREG_BL_MANU = 1.
2. Set SREG_MUTE_DISPLAY = 0.
3. Set SREG_BL_GAIN = 255.
4. Send ECS command OSD_OFF.
5. Send ECS command CSC_BYPASS_INIT_SET.
6. Wait for successful retrieval.
7. Set SREG_BRIGHT = 100(max).
8. Set SREG_ECO_MODE = 0(Standard).
9. Set SREG_TEST_G_LEVEL = 255.
10. Set SREG_GAMMA_EN = 0(OFF).
11. Measure ‘maximum brightness’ and ‘panel peak white color’ and record x, y and Y data.
12. Confirm this data
[Case A] if y => 0.298, check that the brightness is equal to or greater than Spec A.
Set and save WB register A as follows :-
WB_GAM_G01 = 124
WB_GAM_G02 = 120
WB_GAM_G03 = 116
WB_GAM_G04 = 118
WB_GAM_G05 = 112
WB_GAM_G06 = 109
WB_GAM_G07 = 108
[Case B] if 0.293 =< Y < 0.298, check that the brightness is equal to or greater than Spec B.
Set and save WB register B as follows :-
WB_GAM_G01 = 126
WB_GAM_G02 = 124
WB_GAM_G03 = 122
WB_GAM_G04 = 123
WB_GAM_G05 = 120
WB_GAM_G06 = 119
WB_GAM_G07 = 118
[Case C] if y < 0.293, check that the brightness is equal to or greater than Spec C.
Set and save WB register C as follows :-
WB_GAM_G01 = 128
WB_GAM_G02 = 128
WB_GAM_G03 = 128
WB_GAM_G04 = 128
WB_GAM_G05 = 128
WB_GAM_G06 = 128
WB_GAM_G07 = 128
· If the brightness is lower than the spec consider the panel as no good.
Set up mode for Gamma Adjustment

2. Set SREG_GAMMA_EN = 1 (On).
3. Set SREG_COL_MTRX_IDX_OFF = 4.
4. Set SREG_COL_MTRX_IDX_L = 4.
5. Set SREG_COL_MTRX_IDX_M = 4.
6. Set SREG_COL_MTRX_IDX_H = 4.
7. Set SREG_G_GAM_IDX_OFST = 15.
Set up Trident Internal SG and Brightness measurement
1. Set up SREG_TEST_G_LEVEL = 204.
2. Measure brightness A.
3. Set up SREG_TEST_G_LEVEL = 102.
4. Measure brightness B.
5. Set up SREG_MEASURE_GAM_01 = (brightness B/brightness A)*10000.
6. Send Gamma_Tbl_Search_1 command.
7. Set up SREG_TEST_G_LEVEL = 153.
8. Measure brightness C.
9. Set up SREG_MEASURE_GAM_02 = (brightness C/brightness A)*10000.
10. Send Gamma_Tbl_Search_2 command.
11. Wait for calculation in UCOM.
12. Calculate register SREG_G_GAM_IDX_OFST using the formula
13. Set SREG_G_GAM_IDX_OFST.

 SELF DIAGNOSTIC SOFTWARE
The identification of errors within the WAX3 chassis is triggered in one of two ways :- 1: Busy or 2: Device failure to respond to IIC. In the event of one of these situations arising the software will first try to release the bus if busy (Failure to do so will report with a continuous flashing LED) and then communicate with each device in turn to establish if a device is faulty. If a device is found to be faulty the relevant device number will be displayed through the LED (Series of flashes which must be counted).

Balancer error

Note *1: It is judged as HFR Error when Safety Shutdown is activated due to either of FRC ACK error, 1.5V error, 2.5V/3.3V error, or Panel 12V error.
Note *2: The number of LED-blinking times for Internal temperature error is also used for BH-board temperature error: these two errors are distinguished from whether TV Shutdown is involved
or not.
