Sony RMPJHS1, SUHS1, VPLHS1FP service manual LOW Mode of INPUT-A, MID/HIGH/LOW Mode of Video

3) LOW Mode of INPUT-A

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

2.Set the GAIN G to MID mode value at “_35” with the LOW mode of the W/B.

Set the GAIN B that is equal to MID mode value at “_30”. (Set the GAIN B to the same as MID mode value “_30”.)

3.Set the GAIN R that is equal to MID mode value. (Set the GAIN R to the same as MID mode value.)

4.Set the BIAS R, G and B that are equal to MID mode value. (Set the BIAS R, G and B to the same as MID mode value).

5.Measure the chromaticity (x, y).

6.Input the 30 IRE signal to INPUT-A.

7Adjust the chromaticity (x, y) to the values measured in step 2, by the BIAS R and B of W/B HIGH mode.

8.Input the 80 IRE signal to INPUT-A.

9.Adjust the chromaticity (x, y) to the values measured in step 2, by the GAIN R and B.

10.Repeat above steps 6. to 9. until the chromaticity become the following values.

x ±0.002, y ±0.004 (The x and y are the values measured in step 5.)

4) MID/HIGH/LOW Mode of VIDEO

1.Input the VIDEO signal of NTSC or PAL.

2.Set the BIAS R, G and B and GAIN R, G and B of MID, HIGH and LOW mode of W/B that are equal to the values of corresponding items in INPUT-A. (Altogether 18 items)

3.Set the GAIN G only of MID mode value at “_16” in INPUT-A.
