DESCRIPTION OF MICOM
1. Feature of MICOM Function
1-1. Signal Selection
(1) Input signal selection : RGB1(Analog)/RGB2(Analog)/RGB3(Analog/Digital)/Video/S-Video/Component
(2) A/V color standard automatic signal selection : NTSC/PAL/SECAM/NTSC 4.43/PAL M/PAL N/PAL 60
-> Automatic system detection
(3) Specification of PC input signal : Refer to "PC Input Specification Table".
(4) Specification of Component input signal : 480I,480P,DVD 625Line,576P,720P,1080I 50Hz,1080I 60Hz
1-2. Video Interpolation Extension, Compression Support
You can control the correspondent IC like scaler after discrimination of input signal. If the resolution is lower than
XGA, you can extend it to the XGA scale. Or if it is higher than XGA, you can compress it to XGA scale.
* Resolution : Set the resolution lower than 1280x720 in order to adjust the picture of panel (resolution:1280x720) to the screen.
1-3. Judging No Signal
OSD,SOUND Mute
1-4. Video Signal Adjustment
(1) Analog RGB(PC) input : Contrast, Brightness, Color(R, G, B)
Clock, Phase, H Position, V Position
(2) Digital RGB (DVI) input : Contrast, Brightness, Colorr(R, G, B)
Clock, Phase, etc. are automatically adjusted on auto tracking mode, but noise can be included in the signal
owing to the IC specification and also they can't be adjusted precisely according to the signal pattern.
So the manual to adjust Clock, phase, etc. manually.
1-5. Sound Signal Adjustment
Volume, Mute,DASP,AVL,MIC
1-6. Other Functions
Item REF
ARC(Aspect Ratio Control) Analog/Digital RGB :4:3,16:9 mode Toggle funtion
Video/S-Video/Component :4:3,16:9 ,zoom 1,zoom 2,zoom 3 mode Toggle funtion
ZOOM Adjusting the magnification of zoom by shortened key.(+/- 25 level)
Checking Lamp Time Checks used time to now and displayes the fact when replacing time gets.
OSD Language Selection Korean, English, French, German, Italian, Spanish, Chinese,Japanese
Auto Tracking Automatically controlling CLOCK, PHASE
Set ID Characteristic number of set which is used to adjust the funtions of set with PC by
connecting RS-232C terminal(1~99).
When the Set ID specified in PC P/G accords with the set ID specified in the
set,the funtions of set can be controlled by using the menu of PC P/G.
APC(Auto Picture Control) By using this menu,you can select "clear","soft","comfortable" or "off" in Video,S-
Video,Component.
Audio Input By using this menu,make speaker output by selecting audio input R/L or Mic.
And you can use R/L by connecting the stereo output from DVDP or STB.
1-7. Controlling Power
(1) ST-BY -> Power On key in -> Main Power On -> Fan Off -> Blue Background -> Lamp On
-> LOGO ON -> Video output or No signal
(2) Power Off key in -> Lamp Off -> Audio mute -> Fan Off -> Main Power Off -> ST-BY
1-8. Data Saving
EEPROM(24C256), EEPROM IIC BUS

1-9. Warning OSD and Controlling LED
Operation indicator LED Orange 7 Stand-By
Orange(flashing) 7 lamp is cooling as power out(1 minutes),Ignore the power on input.
Green 7 Run
Green(flashing) 7 7 Sec. : Cooled for a minute before turning off the lamp.
7 25 Sec. : Didn't cool the lamp for a minute while turning off the lamp.
Off 7 Off (the state that AC S/W is off or the Power cable isn't connected)
Lamp Indicator LED Red 7 Warning the life of lamp, Needing to replace the lamp ( over 10000H)
7 Displaying OSD for lamp warning when power on.
Red(flashing) 7 Lamp on error. ( case of lamp isn't on when power on )
7 Turn on the lamp and start the detect after 5 seconds.
When occuring error,turn off the lamp at once.
Green(flashing) 7 Warning of lamp case open
7 Power off forcedly, Not Power on
Temperature indicator Red 7 High temperature.Power off
LED Red(flashing) 7 Warning of fan1 malfunction. (Perceived after 20 ~ 60 seconds because it takes a
little time to check internally. )
Green(flashing) 7 Warning of fan2 malfunction. (Perceived after 20 ~ 60 seconds because it takes a
little time to check internally. )
1-10. Checking and Initiating the Lamp Time
Used lamp time is displayed on the menu.
(1) Over 10000 hours : Informs warning.(Red LED), Displaying warning OSD when power on.
If you don't initializing the lamp,it is always display warning OSD on screen when turning on the lamp.
(2) Initiation : Used time must be initiated by the user after replacing the lamp.
You can move to the next service menu by pressing the "MENU" key,and when you press the "MENU" key
continuously,you can move to "LAMP TIME RESET" menu.
If you press the "+" key (VOL+) in this menu,the user lamp time is reset.And then press the "ENTER" key to come out
of service menu.
Caution : Changing the set value in other menus besides "LAMP TIME RESET" or input other keys besides "MENU" key can cause
serious problem to the lamp.Always use the "ENTER" key to cancel the service menu in "LAMP TIME RESET" menu.
1-11. Remote Mouse Control
(1) Funtion the mouse of PC.
(2) Apply the 16 directions and left,right click/drag.
(3) Apply the function of the PS/2,MAC Mouse.
1-12. DDC1/2B
Use the specified IC-24LC21 for DDC1/2B to write EDID table data on 24C21 through adjustment Zig.
