LED BLINKING ERROR CODE SERVICE MODE AND ADJUSTMENTS 

SELF DIAGNOSTICS
When safety shutdown occurs, LED display reports the cause by using the Lighting patterns as indicated below. Since there are various failure items in WAX model. Light blinking is used so that shutdown causes can be judged from the number of blinking times. The items corresponding to the number of blinking times are indicated as follows

How to enter Service Mode
Service adjustments to this model can be performed using the supplied Remote Commander RM-GA008
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.
(STBY) - (ON SCREEN DISPLAY) -  (CH 5) - (VOLUME +)  - (POWER)
3. The menu will then appear on the screen.
4. Move to the relevant command using the up or down arrow buttons 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.
Aging
1. Aging setting
i. Set no signal and monitor as aging mode.
2. Aging condition
i. Aging condition before white balance adjustment is as follows;
Supply Voltage : Rating
Time : 20 minutes or over
(AGING_TIMER registor setting)
Ambient temp : 22 - 28°C
Brightness : Brightness is set by aging mode
Input : Set no signal except digital and analog RF (video/component/PC)
3. LED lighting pattern during aging
In case that AGING_TIMER > 0
Green (0.5s) >
off (0.5s) > Green (0.5s) >  off (0.5s)
Notes: Green (Power LED is ON/OFF)
In case that AGING_TIMER = 0
Green (3.0s) >
off (3.0s) > Green (3.0s) > off (3.0s)
Notes: Green (Power LED is ON/OFF)
Note:
If set has been put on surface down, brightness surface irregularity is caused by static electricity. If so be, turn set over or keep it upright more than 30 seconds. As surface irregularity is vanished away, then check the set.
Signal Level Adjustment
Set up of AD calibration 1 adjustment for terrestrial analog
The following adjustments are done via ECS.
1. Send ECS_ADJUST_LEVEL_SETTING_INIT command
