Chassis.

(1) Because this is not a hot chassis, it is not necessary to use

an isolation transformer. However, the use of isolation
transformer will help protect test instrument.

(2) Adjustment must be done in the correct order.
(3) The adjustment must be performed in the circumstance of

25±5°C of temperature and 65±10% of relative humidity if
there is no specific designation.

(4) The input voltage of the receiver must keep 100-240V~,

50/60Hz.

(5) The receiver must be operated for about 15 minutes prior

to the adjustment.

In case of keeping module is in the circumstance of 0°C, it
should be placed in the circumstance of above 15°C  for
2hours.
In case of keeping module is in the circumstance of below
-20°C, it should be placed in the circumstance of above
15°C  for 3hours.

After RGB Full white HEAT-RUN Mode, the receiver must

be operated prior to adjustment.

Enter into HEAT-RUN MODE

1) Press the POWER ON KEY on R/C for adjustment.
2) OSD display and screen display PATTERN MODE.

* Set is activated HEAT-RUN without signal generator in

this mode.

* Single color pattern(RED/BLUE/GREEN) of HEAT-RUN 

mode uses to check PANEL.

[gray pattern that left & right is black and center is white

signal(Refer below picture)].

(3) Adjust by commanding AUTO_COLOR_ADJUST.

(1) We confirm whether “0xAA(RGB)” address of EEPROM

“0xA2” is “0xAA” or not.

(2) If “0xAA(RGB)” address of EEPROM “0xA2” isn’t “0xAA”,

we adjust once more.

(3) We can confirm the ADC values from “0xA4~0xA9(RGB)”

address in a page “0xA2”.

* Manual ADC process using Service Remocon. After enter

Service Mode by pushing “ADJ” key, execute “ADC Adjust”
by pushing “

G

* Using ‘power on’ button off the control R/C, power on TV.

If you turn on a still screen more than 20 minutes, (Especially
digital pattern, cross hatch pattern) after image may be occur in
the black level part of the screen.
