FLUX Support Team
  • Updated

Description

The reason a touch screen is nonresponsive can be complex. It could be caused by a system failure, faulty screen, USB-C cable, RK board, or mainboard, etc. 

Please follow the steps below to troubleshoot the issue.


Possible Causes

  1. The system fails (Re-update the firmware, reset to factory, or reflash the RK board)
  2. The USB-C cable is having a problem.
  3. The cables are not properly plugged.
  4. The touch screen itself is broken. 
  5. The RK board is down. 
  6. The mainboard is down.

 

Tools

  1. 3mm Allen key (Optional)
  2. T8 Torx screwdriver (Optional)
  3. Mouse (Wired mouse is recommended)

 

Step 1

Find the IP address of your machine using Beam Studio if possible.

 

Determine your result and the next action to take:

  • Yes, the IP can be found >> Step 2
  • No, the IP can't be found >> Step 1.1

 

Step 1.1

Plug the mouse into one of the USB ports at the back of the machine to see if the little circle (cursor) can be moved around. Then, try selecting options on the panel by left-clicking, as in the video below.

 

Determine your result and the next action to take:

  • Yes, the panel can be controlled by the mouse >> Step 3
  • The cursor can't be moved by the mouse >> Step 1.2
  • The cursor can be moved, but when left-clicking, it has no response >> Step 4

 

Step 1.2

Try using the other USB at the back of the machine and see if the machine can be controlled.

 

Determine your result and the next action to take:

  • Yes, the panel can be controlled by the mouse >> Step 3
  • No, the panel can't be controlled by the mouse >> Contact Customer Service
    • Possible Cause:
      1. The mainboard is faulty
        (The USB ports are dead, which may not be related to the touch function)

 

Step 2

Copy the IP address and write it down on the address bar of your browser.
Then add :8000 at the end of the IP address of the machine to have the screen of the machine showing on the browser.

  • For example, in the photos above, my machine has the IP address 192.168.1.217.

 

  • Therefore, I will be putting the IP address in the browser like this 192.168.1.217:8000.

 

  • After that, you should get the screen of the machine, and it should be able to control the machine.

Determine your result and the next action to take:

  • Yes, the panel can be controlled using the browser >> Step 3
  • No, the panel can't be controlled using the browser >> Step 4

 

Step 3

Reset to the factory and try the touch again.

5-7 Reset to Factory

 

Determine your result and the next action to take:

  • The touch function works >> Problem Solved
    • Possible Cause: The system failed
  • The touch function still does not work >> Step 3.1

 

Step 3.1

Update or re-update the firmware to the latest version using Beam Studio. (Download Link)
After the update, try the touch function again.


 

Determine your result and the next action to take:

  • The touch function works >> Problem Solved
