• Vertical Angle
• Vertical Bow
Just in case the TV set requires a full geometries adjustment, please proceed first with
Vertical according to the above order, and after that, adjust Horizontal according to the
above order.
Horizontal Shift
Adjust the horizontal shift so that the picture is centred.

The effect of this adjustment is shown in figure 3.
• When the volume up button is pressed, horizontal scanning increases.
• When the volume down button is pressed, horizontal scanning decreases.
• Press the stand-by button on the remote control to store.
Pin Phase

• When the volume up button is pressed, side pincushion changes.
• When the volume down button is pressed, side pincushion changes.
• Press the stand-by button on the remote control to store.
Pin Amp
Adjust the Pin Amplitude so that the picture is centred.
The effect of this adjustment is shown in figure 5.
• When the volume up button is pressed, side pincushion changes from pincushion to
barrel shape.
• When the volume down button is pressed, side pincushion changes from barrel
shape to pincushion.
• Press the stand-by button on the remote control to store.
Corner Amplitude
Adjust the Corner Amplitude so that the picture is centred.
The effect of this adjustment is shown in figure 6.
Note: This adjustment affects to upper and lower sides.
• When the volume up button is pressed, side pincushion changes from pincushion to
barrel shape.
• When the volume down button is pressed, side pincushion changes from barrel
shape to pincushion.
• Press the stand-by button on the remote control to store.
