• Horizontal shift

• Horizontal size

• Pin phase

• Pin amplitude

• Vertical angle

• Vertical bow

• Upper corner correction

• Lower corner correction

• Extreme corner correction

Just in case the TV set requires a full geometry adjustment, please proceed  first with Vertical according to the above
order, and after that,  adjust Horizontal according to the above  order.

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, the picture moves to the left.

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

Adjust the Pin phase so that the picture is symmetrical top and bottom.
