I was able to download the service manual for the D1. I followed the instructions, and was able to get into the service menu. I tried to recalibrate my touchscreen because I wasn't able to access the buttons on the far right bottom of the screen. It seems to be off by almost a 1/2 inch. Anyway, I tried the recal and when I entered the mode to set the point of touch, it wouldn't recognize where I was touching it. Bottom line is I wasn't successful in recalibrating the touch screen. Any suggestions?
