4 Alignments and Adjustments
This section of the service manual explains how to use the DDC JIG to adjust the black, red, green, and blue
levels of the FPD when you replace the AD Board, and how to update the microprocessor when you
change the Panel or Lamp(s).
4-1 General Alignment Instuction
1.
Usually, a color TV-VCR needs only slight touch-up adjustment upon installation.
Check the basic characteristics such as height, horizontal and vertical sync.
Use the specified test equipment or its equivalent.
Correct impedance matching is essential.
Avoid overload. Excessive signal from a sweep generator might overload the front-end
of the TV. When inserting signal markers,do not allow the marker generator to distort
test result.
Connect the TV only to an DC power source with voltage and frequency as specified on
the backcover nameplate.
Do not attempt to connect or disconnect any wire while the TV is turned on. Make sure
that the power cord is disconnected before replacing any parts.
To protect aganist shock hazard,use an isolation transform.

4-2 Adjustment Procedures
Use the following procedures whenever you replace the AD Board, Panel, or one or both of the Lamps.
4-2-1 (a) Color Auto Adjustment
1.
After displaying 16-Gray pattern of XGA mode press channel “+”, ”–”, and “menu” buttons.
2.
During normal execution of Auto Algorithm the screen image may change. If Auto Algorithm does
not excute properly, try one more.
3.
After normal execution of Auto Algorithm, confirm optimal settings by observing the contrast of
several different patterns on the display.
4-2-2 (b) White Balance Adjustment
1.
After displaying white pattern (on the WUXAG mode), press channel “+”,”–” and “Exit” buttons.
2.
During normal execution df white balance the screen, image may change.
