ADJUSTMENT
1. Flicker adjustment
●Condition (same conditon as it is used in the
previous models)
Video Source: VIDEO
Video: Luster white 30%~50%
BRIGHT: MAX
MODE: ZOOM
● Adjustment procedure
q
Display luster white 30%~50%.
w
Place a flicker adjustment jig to the monitor and observe
the waveform with an oscilloscope.
e
Turn VR200 and adjust it to make the amplitude of the
waveform to minimum.
Oscilloscope range: 20mV, 0.5mS
● Note
q
In checking the screen after the adjustment, shake the
monitor up and down in order to confirm that the screen
does not flicker. (This check is also carried out on the 07
model.)
w
Noise due to AC200V can be observed in the flicker
adjustment jig and oscilloscope, and thus carefully set up
the power supply and GND of the jig and oscilloscope.
* In the 07 model, GND of the measurement equipment
has been floated.
2. Automatic adjustment of RGB amplitude
and WB VCOM amplitude
● Adjustment requirement
Input signal: Input white 100% (NTSC) in VIDEO1
● Adjustment method
q
Press Auto Adjust on the Test Mode Main screen.
w
Press RGB on the Auto Adjust screen.
e
After the automatic adjustment, "Auto Set OK" will be
shown to indicate the completion of the adjustment

3. TINT/PHASE adjustment
●
Adjustment requirement. The adjustment is
required to the model for PAL regions (other
than K and R)
Input signal:Input magenta (PAL) in VIDEO1.
● Adjustment method
q
Press Auto Adjust on the Test Mode Main screen.
w
Press Tint/Phase on the Auto Adjust screen.
e
After the automatic adjustment, complete the adjustment
by confirming that “Auto Set OK” is displayed and that
no flickering or horizontal stripes are observed on the
magenta.
