3-5. YH Setting
Test point:
TP51, TPS7
Test equipment: Oscilloscope
Adjusting point: RV92, RV62
1.
2:
Remove the lens cap and adjust RV92 (M.PED) until
pedestal level at TP57 shows 50 mVp-p.
Shoot the gray scale to fill whole screen. Adjust lens
aperture until waveform level of 450 mVp-p is
obtained at TP51.
. Adjust RV62 so that white part of the gray scale shows
720 mVp-p at TP57. (Hereafter, this level is called
gray scale shooting.)
3-6. R Matrix Adjustment
Test point:
TP55S
Test equipment: Oscilloscope
Adjusting point: RV53, RV54
1. Shoot the color bar chart to fill whole screen and to
obtain 630 mVp-p at white at TP57. (Hereafter, this
operation is called a color bar shooting. )
2. Check waveform image at TP5S is doubled or not.
If doubled adjust RV53.
3. Turn RV54 fully clockwise.
