Procedure:
1. Probe impedance matches 50 ohm
2. Change Timing and pattern of pattern generator :
Timing : 800x600@60Hz (H:37.879Khz,V:60.317Hz)
pattern : full white
3. Adjust user & factory OSD values to default.
4. Open Factory OSD, and select color wheel delay item.
5. The image will become white.
6. Put the detector on the screen that white image was projected.
7. Watch the oscilloscope and notice the square waveform
8. Use the “ ” and “ ” key to increment or decrement the color wheel delay value
9. No matter the waveform is square or not, let the waveform was lagged first
Lag Exact
10. Then increment or decrement the value to let the waveform to be square
11. Do not adjust too much, let the signal get ahead, if it happens, go back to step 7 and do
it again.
