Figure 8-12 How to adjust the waveform (42” SD v2)
1) Make Full White on Screen.
2) Observe waveform using Oscilloscope.
a Check OUT4 TP in Y-buffer(upper).
Observe the waveform of the third waveform of 1TV-Field.
b Adjust the division of oscilloscope like the left picture
c Adjust the period of Vset as 10µS, that of -Vsc(1) as 20µs,
that of -Vsc(2) as 5µs, turning VR (Variable Resistor)
(only,when you adjust each period of -Vsc(1) & -Vsc(2)
adjust Vertical Division of oscilloscope as '2V or 5V')
d VR for Vset : VR5003 (Y_main)
VR for -Vsc(1) : VR5001 (Y_main)
VR for -Vsc(2) : VR5002 (Y_main)
