4. Vsw adjustment
Measuring point: The voltage between test point Vsw on the high voltage PKG and GND (chassis GND)
Adjustment: Adjust VR2 so that the voltage of Vsw becomes Vsw value of drive voltage label ± 0.5V.
5. Vp adjustment
Measuring point: The voltage between test point Vp on the high voltage PKG and GND (chassis GND)
Adjustment: Adjust VR1 so that the voltage of Vp becomes Vp value of drive voltage label ± 0.5V.
6 OPERATION CHECKS
After replacing the PDP module or a part of the PDP module, perform aging with a fully white
screen for 30 minutes or more. Then check the screen by displaying fully red, green, and blue
screens, color bars, and gray scales.
Note: If any irregularity in lighting of cells of the screen is observed upon inspection after
extended storage of the PDP, perform aging for another 1 hour or so with a fully white screen.
