Clean around the edges of the touch panel up under the cover...dirt and grime can get up in there...then initialize the op panel with U201 then do a U906....that will fix the problem a majority of the time.....

Kidaver is right, try that first. it's only worked for me 50% of the time.
I replace the panel if that doesn't fix it. Its a resistive touch panel that sits on top of the LCD as a separate assembly.
Here is the part number:
302H094270 PARTS,TABLET OPERATION,SP

If you do replace the touch panel, make sure to re-flash the firmware on the machine just to be safe(there's a TB about that), then re-calibrate ( u201).

Good luck
