3-7. Brightness voltage setting and contrast adjustment
1. Preparation
• AC adaptor or voltage regulator
• Digital oscilloscope
2. Adjustment procedure
(1) Start up Test mode Menu1.
(2) Select GRAY SCALE (10 step).
(3) Trigger VB waveform (CP335) by FRP(CP346) signal to adjust as noted below.
(4) Adjust RGB-AMP VR (VR340) so that pedestal-pedestal voltage of VB(CP335) signal is 3.5 ±
0.05 V.
(5) Adjust contrast VR (VR344) so that contrast terminal voltage (CP305) is 3.0 ±0.05 V temporary.
(6) Adjust Bright VR (VR381) so that potential between VB (CP335) signal’s pedestal and 3 step is
2.20 ±0.05 V.
(7) Adjust contrast VR (VR344) so that potential between VB (CP335) signal’s pedestal and 10 step
is 2.85 ±0.05 V.
✻Make sure that waveforms are not distorted.
