Turn the SCREEN VR until “MRCR G B” and “MRWDG” are green and those value are about 100. (The incorrect SCREEN Voltage may result that “MRCR G B” and “MRWDG” should be red) 4-2 Samsung Electronics Alignment and Adjustments 4-6 E2PROM (IC902) Replacement 1. When IC902 is replaced, all adjustment data revert to the initial values. So, all adjustment values when servicing should be readjusted. 2. After IC902 is replaced, connect the AC power supply cord. 3. Turn the power switch ON. 4. In stand-by, warm up the TV for at least 10 seconds. 5. Power on the TV. 4-7 White Balance Adjustment ■ Equipment : Color-Analyzer (CA-100) ■ Input Signal : Pattern signal (Toshiba pattern) 1. Select STANDARD from the menu. 2. Input an 100% White pattern. 3. Enter the “Service Mode”. (Refer to “4-8 Service Mode”) 4. Warm up the TV set at least for 30 minutes. 5. Input a Toshiba pattern signal. 6. Enter the “Video Adjust1”. (Refer to table 2.) - Adjust “Sub Contrast” so that Y (luminance) becomes 65 ft ± 3. - Use “Red Drive” and “ Blue Drive” to adjust High-Light (x : 265, y : 265) - Adjust “Sub Bright” so that Y (luminance) becomes 1.2ft ± 0.3. - Use “Red Cutoff” and “Blue Cutoff” to adjust Low-Light (x : 265, y : 265). 7. Adjust CA-100 so that the final adjustment value can be fixed. 8. Use the Channel Up/Down (▲/▼) buttons to move the cursor on the adjustment modes. 9. Use the Volume +/- buttons to change the adjustment value. Samsung Electronics 4-3 Alignment and Adjustments Table 2.

To enter the “Service Mode”, Press the remote-control keys in this sequence : - If you do not have Factory remote-control PICTURE OFF DISPLAY() MENU MUTE PICTURE ON - If you have Factory remote-control PICTURE ON DISPLAY() FACTORY 2. After the Service Mode is entered, the initial screen is as shown in the figure below. xx xx xx * These hexa digits are check sum value which * depends on the MICOM version. If check sum value is changed, the value of E2PROM Data newly initialed. 3. Use the Channel Up/Down buttons to move the cursor in the adjustment parameters. Note : 2 - When CRT, CRT PCB, FBT, E PROM (sometimes MICOM) is replaced, the adjustment values should be controlled. - After the Service adjustment is completed, Do not select “Reset” in the service mode menu. (After above procedure is done, power is on initially and the “Plug and Play” will be operated.)
