How can I recalibrate the touch area from a PCD7.D7xx panel?
It might happend that the touch area of a PCD7.D7xx panel doesn't respond anymore: In this case most likely the calibration has been lost and the touch area has to be recalibrated. In many cases the loss of the calibration can be avoided by a boot and firmware update (see related link below)!
Procedure for recalibrating the touch screen
- Switch off the panel
- Open the back cover (4 screws)
- Locate the single jumper J1 or J5 also indicated with C
- Move the jumper on the position C
- Swicth the power on
- Calibrate the screen with a fine pointer (on the cross 3 times)
- Swich the power off
- Move the jumper to the inital position
- Close the cover
- Switch the panel on
More details about the calibration with drawings for each panel type are available in hardware manual 405_1200_037 which is availbale on the PCD support page:
Always use the latest PCD8.D81W version: the actual version is 5.22. In this version some boot / firmware versions have to be updated, see related link to the FAQs 100823 and 100716!
