Question
What causes diagnostic tool "touchscreen unresponsive" faults?
Answer
Screen protector interference and touch controller failure.
Explain
Unresponsive touchscreens disable tool operation. CHEPQ recommends removing thick screen protectors and testing the touchscreen without accessories—replacing the touch controller if unresponsiveness persists ensures tool usability.
