3-5. White Balance Adjustment on Servicing

3-5-1. Signal Level Adjustment

1.Input the 10 STEP signal to INPUT-A.

2.Warm up the unit at least 10 minutes. Enter the V- AMP/BRT adjustment mode from the Service mode

as follows :

Service Mode → MENU → DEV. ADJ → P. DRV

→ VAMP/BRT.

3.Measure TP813, TP817, and TP821 on the C board by osciloscope. Adujust V AMP/BRT so that the minimum value in all black level is 2.8 V.

4.Input the 95 IRE and 100 IRE STEP signals.

5.Set the unit in G-only mode.

6.Enter the P.DRV on the MENU screen by the DEV. ADJ.

7.Discriminate the 95 IRE and 100 IRE by the V- AMP/CONT controls of the P.DRV.

8.Set the unit in R-only mode.

9.Discriminate the 95 IRE and 100 IRE by the V- AMP/SUB CONT R controls of the P.DRV.

10.Set the unit in B-only mode.

11.Discriminate the 95 IRE and 100 IRE by the V- AMP/SUB CONT B controls of the P.DRV.

3-5-2. White Balance Adjustment

1) HIGH Mode of INPUT-A

Input the 10 STEP signal to INPUT-A, and observe the chromaticity of each luminance.

When varying the chromaticity of each luminance, perform the following adjustments.

1.Input the 100 IRE FLAT FIELD signal to INPUT-A.

2.Measure the chromaticity (x, y).

3.Input the 50 IRE FLAT FIELD signal to INPUT-A.

4.Adjust the chromaticity (x, y) to the values measured in step 2 by the VAMP/SUB CONT R and B of the P. DRV.

2) LOW Mode of INPUT-A

1.Input the 80 IRE FLAT FIELD signal to INPUT-A.

2.Set the GAIN G to 60 with the LOW mode of the W/B.

3.Measure the chromaticity (x, y).

4.Input the 25 IRE FLAT FIELD signal to INPUT-A.

5.Adjust the chromaticity (x, y) to the values measured in step 3 by the BIAS G and B of the LOW mode of the W/B.

6.Repeat above steps 1 to 5 until the chromaticity become

the following values.

x ± 0.002, y ± 0.003 (The x and y are the values measured in step 3.)

3) HIGH Mode of VIDEO

Switch the input to COMPONENT from INPUT-A by the SET SETTING of the Menu screen.

Input the 15k COMPONENT 10 STEP signal to INPUT-A, and observe the chromaticity of each luminance.

When varying the chromaticity of each luminance, perform the following adjustments.

1.Input the 100 IRE FLAT FIELD signal to INPUT-A.

2.Measure the chromaticity (x, y).

3.Input the 50 IRE FLAT FIELD signal to INPUT-A.

4.Adjust the chromaticity (x, y) to the values measured in step 2 by the VAMP/SUB CONT R and B of the P. DRV.

4) LOW Mode of VIDEO

1.Input the 80 IRE 15k COMPONENT FLAT FIELD signal to INPUT-A.

2.Set the GAIN G to 60 with the LOW mode of the W/B.

3.Measure the chromaticity (x, y).

4.Input the 25 IRE FLAT FIELD signal to INPUT-A.

5.Adjust the chromaticity (x, y) to the values measured in step 3 by the BIAS G and B of the LOW mode of the W/B.

6.Repeat above steps 1 to 5 until the chromaticity become

the following values.

x ± 0.002, y ± 0.003 (The x and y are the values measured in step 3.)
