Lilliput 669GL touch not working

I have recently purchased a lilliput 669GL and have installed it into the 2DIN bezel. I installed its touchscreen drivers but the screen seems to think it is being touched in I think the upper right corner area. When I select calibrate with the mouse it acts as if I am touching the screen when I am not. When I DO touch the screen the mouse is being dragged from the upper right corner area. Has any one had this problem before? I have triple checked to make sure that the ribbon cable for the touch feature is well seated.

Having the same issue except mine us to the lower left corner. I checked the 4pin ribbon cable as suggested and still no joy. I ordered a new touch pad from mobile computing solutions for $9.99. Hopefully this resolves the issue. Will post if successful.

no, you overtightened the 4 screws in holding the display to the bezel. play with the tightness of the screws, and it should nearly fix it's self.

Soundman98, the issue did not start for me with overtightening. One day I came out to the car and the cursor wouldn't move from the lower left corner. I kept playing around with it and I noticed that if I held it it would move toward the center but would re-pin itself back to the lower left corner once my finger was removed. I took it apart, tried the heat trick and it improved a bit. Having dealt with similar issues with other touch screens, I felt it was the overlay. I purchased a new one and now everything is working fine. Most of the issues with the Lilliputs seem to be with the overlay. They are easy to replace and cheap $10. Over the long haul it is just better to replace it and not hassle with measuring resistances and playing around with heat around electronics.
