ADJUSTMENT INSTRUCTION 1. Application Object These instructions are applied to all of the MODELS of LCD MONITOR, MF-02HA. 2. Notes (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. But, it can be changed in consideration of mass production. (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 220V, 60Hz in adjusting. [ Input voltage is possible from 85V to 260V because the power voltage applied to this chassis is Wide-Range. But, adjustment should be operated in 220V/60Hz if there is no specific designation. (5) The receiver must be operated for about 15 minutes prior to the adjustment. ¤ After receiving 100% white pattern(06CH), the receiver must be operate prior to adjustment.(Or white condition in HEAT-RUN mode) ¤ŁEnter into HEAT-RUN mode - Select HEAT RUN OFF by pressing ADJ button on Remote Control for adjustment. - Press the VOL + button in HEAT-RUN OFF. (OSD displays HEAT-RUN WHITE and screen displays 100% full WHITE PATTERN) [ Set is activated HEAT-RUN without signal generator in this mode. [ Single color pattern of HEAT-RUN mode can be used to check PANEL.(RED/BLUE/GREEN) [Caution] If you turn on a still screen more than 20 minutes (especially, Digital pattern[13 CH], Cross Hatch Pattern[09CH]), a afterinage may be occur in the black level part of the screen. 3-2. EDID (The Extended Display Identification Data) Adjustment (1) This is the function that is made for the realization of "Plug and Play" which makes possible to use the user environment right after reorganization by communicating with monitor automatically. (2) EDID DATA for DVI of MF-02HA EDID table = 00 01 02 03 04 05 06 07 08 09 000 | 00 FF FF FF FF FF FF 00 1E 6D 010 | D7 3A 01 01 01 01 33 0B 01 01 020 | 81 40 26 96 08 B7 FB A1 56 48 030 | 98 24 13 48 4B AF EF 00 81 00 040 | 31 59 45 59 61 59 81 80 71 4F 050 | 01 01 01 01 BC 34 00 98 51 00 060 | 2A 40 10 90 13 00 40 26 00 00 070 | 00 1E 00 00 00 FC 00 4D 57 20 080 | 33 30 4C 5A 31 30 0A 20 20 20 090 | 00 00 00 FD 00 3C 78 1F 5B 10 100 | 00 0A 20 20 20 20 20 20 D5 09 110 | 80 A0 20 E0 2D 10 10 60 A2 00 120 | EE F0 75 00 00 18 00 BD (3) EDID DATA for RGB of MF-02HA EDID table = 00 01 02 03 04 05 06 07 08 09 000 | 00 FF FF FF FF FF FF 00 1E 6D 010 | D7 3A 01 01 01 01 33 0B 01 01 020 | 1E 40 26 96 08 B7 FB A1 56 48 030 | 98 24 13 48 4B AF EF 00 81 00 040 | 31 59 45 59 61 59 81 80 71 4F 050 | 01 01 01 01 BC 34 00 98 51 00 060 | 2A 40 10 90 13 00 40 26 00 00 070 | 00 1E 00 00 00 FC 00 4D 57 20 080 | 33 30 4C 5A 31 30 0A 20 20 20 090 | 00 00 00 FD 00 3C 78 1F 5B 10 100 | 00 0A 20 20 20 20 20 20 D5 09 110 | 80 A0 20 E0 2D 10 10 60 A2 00 120 | EE F0 75 00 00 18 00 BD (4) Refer to Service Manual related to EDID communication. 3. Adjustment Items 3-1. Whole Assembly Adjustment (1) White Balance Adjustment (2) SUB-BRIGHT Adjustment : Sub-Bright adjustment in LCD panel is not necessary. Do not adjust sub-bright if there is no specific designation. (3) RGB CUT-OFF Adjustment : Under examination about auto adjustment which correspond to the new Rembrandt1A. 4. Whole Assembly Adjustment Each PCB Assy must be checked by Check JIG Set before assemling.(Be careful about power PCB ASSY which can give a fatal damage to the LCD Module) 4-1.
