4) Updating is staring. 5) Fishing the version uploading, you have to put USB stick and “AC Power” off. 6) After putting “AC Power” on and check updated version on your TV. * If downloading version is more high than your TV have, TV can lost all channel data. In this case, you have to channel recover. if all channel data is cleared, you didn’t have a DTV/ATV test on production line. * After downloading, have to adjust TOOL OPTION again. 1) Push "IN-START" key in service remote controller 2) Select “Tool Option 1” and Push “OK” button. 3) Punch in the number. (Each model hax their number) 4) Completed selecting Tool option. 3.1. ADC Process (1) External ADC (Only adjust in the component mode 480I) • Input the Signal in the Component 1 -Component 480I (Adjusted only this mode) MODEL: 209 in Pattern Generator(480i Mode) PATTERN : 65 in Pattern Generator( MSPG-925 Series) • After enter Service Mode by pushing “ADJ” key, • Enter the 5 item and then Push the “Start” button (2) Internal ADC(Only adjust in the RGB mode) • After enter Service Mode by pushing “ADJ” key • Enter ADC Calibration mode by pushing “ G” key at “5. ADC Calibration • Push the Start button (3) Function Check - Check display and sound • Check Input and Signal items. (cf. work instructions) 1) TV 2) AV (SCART1/SCART2/ CVBS) 3) COMPONENT (480i) 4) RGB (PC : 1024 x 768 @ 60hz) 5) HDMI 6) PC Audio In * Display and Sound check is executed by Remote controller. 4. Total Assembly line process 4.1. Adjustment Preparation • W/B Equipment condition CA210 : CH 9, Test signal : Inner pattern (85IRE) • Above 5 minutes H/run in the inner pattern.

Connect to auto controller or push Adjustment R/C POWER ON -> Enter the mode of White-Balance, the pattern will come out. *Auto-control interface and directions 1) Adjust in the place where the influx of light like floodlight around is blocked. (illumination is less than 10ux). 2) Adhere closely the Color Analyzer (CA210) to the module less than 10cm distance, keep it with the surface of the Module and Color Analyzer’s Prove vertically.(80~100°). 3) Aging time - After aging start, keep the power on (no suspension of power supply) and heat-run over 15minutes. - Using ‘no signal’ or ‘full white pattern’ or the others, check the back light on. • Auto adjustment Map(RS-232C) ** Caution ** Color Temperature : COOL, Medium, Warm. One of R Gain/G Gain/ B Gain should be kept on 0xC0, and adjust other two lower than C0. (when R/G/B Gain are all C0, it is the FULL Dynamic Range of Module) * Manual W/B process using adjusts Remote control. • After enter Service Mode by pushing “ADJ” key, • Enter White Balance by pushing “ G” key at “3. White Balance”.* After done all adjustments, Press “In-start” button and compare Tool option and Area option value with its BOM, if it is correctly same then unplug the AC cable. If it is not same, then correct it same with BOM and unplug AC cable. For correct it to the model’s module from factory JIG model. * Push The “IN STOP” key after completing the function inspection. 4.2. DPM operation confirmation (Only Apply for MNT Model) Check if Power LED Color and Power Consumption operate as standard. • Set Input to RGB and connect D-sub cable to set • Measurement Condition: (100~240V@ 50/60Hz) • Confirm DPM operation at the state of screen without Signal. 4.3. DDC EDID Write (RGB 128Byte ) • Write EDID DATA to EEPROM (24C02) by using DDC2B protocol. • Check whether written EDID data is correct or not. * For SVC main Ass’y, EDID have to be downloaded to Insert Process in advance. 4.4. DDC EDID Write (HDMI 256Byte) • Check whether written EDID data is correct or not. * For SVC main Ass’y, EDID have to be downloaded to Insert Process in advance. 4.5.
