. The explanation of special function

6-1.Auto Search function when no program is stored at turn on the

TV

This function is used when SEARCH CHECK is set to 1. At turning on the TV, the no

program is detected in EEPROM, this auto search mode will be set.

6-2.The EEPROM check function at turning on the TV

Because the BUS data and the setup result of setting item are stored in the EEPROM, the TVcant work when the EEPROM has been damaged. Therefore the machine can automatically detect

the EEPROM at turning on the TV. If the BUS or EEPROM contain error, the machine will readthe initial data after turning on the TV, and set the screen to blue, and the OSD of EEPROM

ERROR PLEASE CHECK is gleamed on the screen. At this time, any operation cant, the TVneed be shut off. When the EEPROM contain part damage, the machine may dont detect it.

6-3.The initial function of EEPROM

When turning on the TV, the CPU can check the EEPROM whether is the replaced new ornot. If the EEPROM is new, in order to assure the TV working, the CPU can automatically read

the initial data. The BUS of TV will work normally according the initial data at this time, and the

BUS data hasnt been written into the EEPROM. At factory mode, after some adjustment datamust be adjusted, the BUS data can be written into the EEPROM. If the operation isnt right, theTV will always work in the initial state at switch on.

6-4.The function of normal remote control unit realizing the

factory

The operation method is shown below:Method one: First set the volume is 0, second press the MENU key to enter PICTURE menu,

then press the digital key to input 6568, the factory function can be realized.Method two: First press REVIEW key, second press VOL- key at the same time, then the

factory function can be realized. Replace these operations, the PROD function can be realized.

The fast method at FACTORY mode: the SLEEP key is used to change among three modes,the REVIEW key is used to exit from factory to normal.

displayed in the process of waiting if the screen function has been set. If the screen left side isntcovered, please set the OSD H.POSI. in the adjustment to the proper position. The hardware

need be changed to produce the phase pulse of CPU if the best state isnt set. The screen functionis not used if the screen is not adjusted.

6-6. Adjustable PP mode function at factory

First press PROD key to enter the ADJUST MENU, second press MENU key orPICTURE key to picture menu, then it can display white word prompt STANDARD behind

the picture. This time press P.P key, the OSD cant disappear. The display character :**** will

be changed by PP mode. The PP mode can be changed, and the changed data is automaticallystored into EEPROM.

6-7.Factory mark setup

The factory mark is divided into two rows, it can set 16 characters every row. The content,switch, font, color and position can be set. The factory mark is set, and at least one row among

them is set to TURN ON state. The factory OSD will be displayed when the screen is blue at nosignal. If the POWER LOGO is set to ON, the screen function is displayed at POWER ON.

1). Operation explanation Press PROD key to enter the factory mode, it had two method to enter the factory mark setup

menu. Method 1: Press P.P key over 4 seconds to enter it. Method 2: When the volume data is

0, press the VOL- and POS- at the same time to enter it.

The factory menu have two screens, it is respectively used to adjust the first and second row.

After entering the setting menu, press the CH+/CH- key to select the option, if the option isselected, there is the yellow piece on the screen to show the adjustment option. The other

OSD that are selected are red, otherwise the OSD are green. Press the VOL+/VOL- key to

select the value of selected option. The adjustment of display content: pressing the CH+/CH- key to select the adjustment item.

The adjustment character is yellow and press the VOL+/VOL- key to adjust the content.

The P.MODE key is used to select the other character at the same row.

The OSD of menu is always displayed, pressing the DISPLAY key to exit after the setupfinish.

The factory mark is set to to see, to get. The display of content, color, font and position are

the same as normal, except the display of that in the factory mode. So the result ofadjusting can be directly seen.

When the OVER.MOD.SW is set to 1 in MENU14, this function is can be used. The

OV.MOD.LEVEL used to adjust over modulate compensation. The program that hasbeen fine adjusted (AFT is OFF) can be adjusted over modulation compensation.

6-10.The realization of automatic adjusting at factory

Press PROD key circularly to enter BUS OPEN mode, the control right of CPU is handed

by the automatic adjustment instrument. The automatic adjustment instrument can send the datathrough the BUS to adjust, the adjusted data must be written into the EEPROM. The data aboutthe automatic adjust and the address of EEPROM are shown below:
