I have this touch display right here:

I'm having a bad issue with the touch screen. Often, the touch panel looses calibration almost 5 minutes after a good "Clear and calibrate". . . If i remove the cover off the back of the display and unplug and plug the digitizer touch panel back in... The calibration is just fine again.
No matter what I do to try and make the contacts on the digitizer plug contact great with the terminals on the circuit board... it looses calibration so fast. This IS a hardware problem for sure. I'm just curious of what I should do to make the connection better from the digitizer to the circuit board. The cable and contacts are in perfect looking condition. This is just an extreme annoyance, especially on long drives.
