To match the sub picture color to that of the main picture.

Main and sub pictures colors differ.

1. Supply an NTSC signal to an External Video Input.
2. Select the NTSC signal as the source for both the main and sub pictures.
3. Connect an oscilloscope to connector JA pin 20

 

(Main PR).

4. Activate the Adjustment mode.
5. Select Item “41 SCLR” in the Main Matrix Function.
6. Adjust data so the PR signal is 0.71 Vp-p max. - 0.66 Vp-p min

(If it cannot be adjusted within this range, set to the lowest closest value)
When using a Leader 480, set to 0.585±0.02Vp-p.

7. Connect an oscilloscope to connector JB pin 5 (Sub PR).
8. Select item “41 SCLR” in the Sub Matrix Function.
9. Adjust so Sub PR = Main PR (+0.0V  -0.05V)

10. Press “ENTER” to save data.

3. Main/Sub Color Level

 

To set the cutoff point for all three CRTs.

Monochrome has a color tint, or incorrect brightness.

3. Press “1”, automatically blanks the screen and sets COL to 0.
4. Set the data to the values given in the table below.
5. Connect the oscilloscope to TP6R.
6. Adjust the Red Screen VR so the black level is 170V, as shown below, or

178V ±1VDC using an DC Voltmeter.

7. Repeat Steps 4 and 5 to set the Blue and Green Screen VRs, using

TP6G and TP6B.

Note:

 

White Balance must be performed after this adjustment.
