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.

3. The following 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

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.

The following adjustments are done via ECS.

1. Send ECS_ADJUST_LEVEL_SETTING_INIT command
2. Ensure noise reduction NR=3 (high),

hreg_P4_cvd2_85 [2:0] = 0
ADJ_COLOR_PAL = 4 (for GA)

3. Set up correspond value to resistors below

Note for Input Signal [GA model] (PAL) included black and white,
75% Y and 75% C, without set up
