Thread: lilliput 7" touchscreen part is not working.

I have this lilliput 7 inch screen the 629GL-70NP/C

Suddenly yesterday the touch screen function stopped working after 4 weeks of working okay

The screen picture itself is displayed verry good.

i was thinking at first that must be windows xp making this error ,but i can calibrate the screen with the software and the finger touch are reconized by the lilliput screen and the computer beeps also when calbrating.
i have tried the 4 point and the other calibration opotions

At the draw test in the calibartion software no lines appear when i move my finger acrros the screen....

In windows nothing happends when i move with the finger on the screen i even cannot see the arrow ,to be sure i have tested the screen on my other computer at home and there the same problem.

i have in mouse options set the trace mouse pointer to on ,to see where the arrow is dissapeared
And when i use the CONTROL key to see where the mouse pointer is at after i touch the screen with my finger ,isee that the mouse pointer hides in the upper/lower left and right corners.

Sometimes it have clicked a icon on the desktop wich with the finger i cannot doubleclick or move away.

With the normal mouse everything just works fine...

i have tested the original and the old drivers with no succes

hardware:
operating sys :windows xp prof sp2
mainboard :jetway 1.5 ghz
ram: 512MB


Thanks
peter.
