Important Note
•
The following voltages and waveforms should be adjusted in the order they are presented.
•
Always adjust the DC levels before the waveform adjustments to most accurately set the Plasma
Display Panel.

•
VSC
115v Used to shape the Y Drive waveform by setting the V Scan level. Measured at the
VSC test points.
•
-VY
-196v Used to shape the Y Drive waveform by setting the negative excursion of the V Set
Check Y Sustain Board Output Voltage with the Voltmeter make sure the -VY and VSC are the same
as the Voltage Label on the upper right side of the PDP.
