Problem: Touch buttons are not responding properly
Solution:
1、If the buttons are misaligned or are difficult to touch, calibrate the touch panel
2、If none of the buttons respond, make sure the LCD screen cable is properly connected
3、If still no response, the front casing may be fitted too tightly to the LCD screen. Loosen the screws between the motherboard and the front casing.
4、If there is still no response, check the serial port information to see if the camera is functioning normally, or directly replace the camera.
