If you notice that your sensor module is not working as intended in the sense that you have at least one area where touches cannot be reported, you might have damaged diodes. You can perform theopen short test in Workbenchto verify if the diodes are damaged in Workbench. If a LED/PD fail the test, it means that you have reduced touch performance in the areas where those are used. For further documentation about how the sensor module works, please refer toIntroduction.
