Your model must be PD-931NB.

If you do not have the manual you can download this from this site.

I am assuming you are following the calibration procedure on page 40 of the manual. (refer page number printed at bottom of pages).

As this is to do with touch screen calibration, the most likely cause of the message coming up is a dirty screen. If cleaning display is not helping then the touch screen circuit is faulty.
