The following geometry adjustments can be carried out. Detailed instructions on how to execute these are given on the following pages Horizontal � Horizontal Shift � E-W Width � Pin Phase � Pin Amp � Corner Amplitude � Corner Symetry Vertical � Vertical Amplitude � S Correction � Vertical Shift � Vertical Linearity � 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 2. � When the volume up button is pressed, the picture moves to the right. � When the volume down button is pressed, the picture moves to the left. � Press the stand-by button on the remote control to store. E-W Width Adjust the E-W Width so that 9% over-scan is achieved. 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 Adjust the Pin Phase so that the picture is symmetrical top and bottom. The effect of this adjustment is shown in figure 4. � 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.
