    IIDifferent fault phases of industrial touch screen correspond to different maintenance

    methods.

    Industrial touch screen is often broken down suddenly at the time of use to a half, not only can make work every time delays is technical personnel in the face of a challenge for the different fault maintenance, fault happens in the industrial touch screen every time won't be the same, different fault the corresponding maintenance method is different also, the following will analyze industrial touch screen together with all of you in different fault how to repair it.

    Industrial touch screen maintenance method.

    1. All the touch screens and buttons are out of order (some of them are normal after starting up) : welding or replacement of touch IC; Welding or replacing the CPU; Write software (button failure, touch normal is a key to get stuck)

    2. The industrial touch screen fails. The buttons are normal: change the touch screen. Add welding or touch control IC.

    3. The touch screen can be corrected, but after correction, it is still partial: when the factory is restored or the grid chip (last 1M), it is intentionally changed to touch screen.

    4, turned on the calibration screen, can be calibrated, but you can't do, always let calibration: change touch screen grid code to write the whole word stock embedded CPU welding or in touch IC check around the touch IC group components for open circuit Cover. The clamshell machine in line

    5. When the touch fails, the machine is normal and the machine is broken: the touch screen is too tight to remove the sealing strip from the touch screen.

    Above is the industrial touch screen different faults corresponding to different maintenance methods.
