Hi,

?

I think you may have lost the calibration constants, at least the ones related to the display.

?

You'll have to do a blind test.

The soft buttons near the screen, the top one is #1 and the bottom one is #6.

?

CAL

MORE (soft button #6)

Soft button #4 for vertical adjustment

Soft button #5 for horizontal adjustment

?

Use the knob or the up and down arrows to see if you can synchronize the image.
