The following geometry adjustments can be carried out. Detailed instructions on how to execute these are given on the following pages

Horizontal	Vertical
• Horizontal Shift	• Vertical Amplitude
• E-W Width	• S Correction
• Pin Phase	• Vertical Shift
• Pin Amp	• Vertical Linearity
• Upper Corner Amplitude	• Vertical angle
• Lower Corner Symmetry	• 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 left.

•When the volume down button is pressed, the picture moves to the right.

•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 pincush- ion to barrel shape.

•Press the stand-by button on the remote control to store.

Upper Corner Correction

Adjust the Upper Corner Correction so that the picture is centred.

The effect of this adjustment is shown in figure 6.

•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 pincush- ion to barrel shape.

•Press the stand-by button on the remote control to store.
