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
s Equipment : Color-Analyzer (CA-100)
s 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”.
- Adjust “Sub Contrast” so that Y (luminance) becomes 40 ft ± 3.
- Use “Red Drive” and “ Blue Drive” to adjust High-Light (x : 290, y : 300)
- Adjust “Sub Bright” so that Y (luminance) becomes 1.3ft ± 0.3.
- Use “Red Cutoff” and “Blue Cutoff” to adjust Low-Light (x : 290, y : 300).
7. Adjust CA-100 so that the final adjustment value can be fixed.
8. Use the Channel Up/Down (v/w) buttons to move the cursor on the adjustment modes.
9. Use the Volume +/- buttons to change the adjustment value.
