Service adjustments (electronic controls)

Sub-Contrast adjustment

Service DAC Adjustment (BRIGH, CONT)
This adjustment is factory set. Do not adjust unless
repairs are made to associated circuit, the CRT Board
or when the CRT is replaced.

Preparation:
1.

Apply a color-bar pattern.

2.

Set the picture settings to normal and color to
minimum.

3.

Connect the oscilloscope to TP47G.

4.

Connect a jumper from TPD2 to cold ground (

).

Procedure:
1.

In the service mode, select DAC “BRIGH” for sub-
brightness to obtain 2.3±0.1V between 7.5IRE and
GND level at TP47G (see Fig. 25)

2.

In the service mode, select DAC “CONT” for sub-
contrast to obtain 3.0±0.1V between 7.5IRE and
100IRE level at TP47G

3.

Remove short jumper

4.

Set the picture settings to normal..

Sub-Brightness

Service DAC adjustment

(

BRIGH

)

Adjustment of this control is important for setting proper
operation of customer brightness and picture controls.
Do not adjust the SCREEN VR after the Sub-
Brightness is set.

Preparation:
1.

Set the picture settings to normal and color to
minimum (no color in picture).

2.

Switch COLOR TEMPERATURE to NORMAL.

Procedure:
1.

Apply a color-bar pattern.

2.

In

the

service

mode

for

making

electronic

adjustments, select the DAC adjustment “BRIGH”
and adjust data so that 7.5IRE part is the same
light output as the 3IRE part.

Tint/Color adjustment

Service DAC adjustment (TINT) (COLOR)
Preparation:
1.

Apply a rainbow color bar signal.

2.

Preset the following controls:

• Brightness . . . . . . . Min.
• Color . . . . . . . . . . . . Center.
• Tint . . . . . . . . . . . . . Center.
• Picture . . . . . . . . . . Max.
• Sharpness . . . . . . . Min.

3.

Connect a jumper from TPD2 to GND (

).

Procedure:
1.

Connect the oscilloscope to TP47B (A-Board).

2.

In the service mode, select “TINT DAC Sub-Tint
adjustment. Adjust until the waveform measured is
as the one shown in Fig. 26.

3.

Connect the oscilloscope to TP47G (TP35) and
cold GND.

4.

Select DAC Sub-Color adjustment “COLOR” and
adjust
