The smart board will also encounter some common faults during use, which will cause inconvenience to users. In view of the faults of smart boards, this paper summarizes the causes and troubleshooting methods of several common faults.
1. Blue screen failure
A blue screen appears on the smart board and prompts an internal system error message, which is usually caused by system file corruption or critical program crashes. You can try to restart it to solve it. If the blue screen still occurs after restarting, you need to contact the manufacturer to reinstall the system.
2. The smart board freezes
If the smart board is obviously stuck when running the program, you can check the network connection first and close other unnecessary programs. If it still freezes after optimization, you can consider restarting the system, restoring factory settings, etc.
3. Touch failure
Partial or complete touch failure of the smart board may be due to driver problems or hardware damage. You can update the driver and check whether the hardware sensors are normal to troubleshoot the problem.
4. Unable To Connect To The Wireless Network
If the smart board cannot search for a wireless network or there is no network after connection, you can restart the router and device, modify the network configuration information, or test the wired network to evaluate the cause of the failure.
5. The system cannot be started
If the smart board only displays a black screen after booting, it may be that the system file is damaged or the hard disk is faulty. The system can be reinstalled to try to resolve this issue.
6. Image quality issues
If there are image quality problems such as variegated color, blurred screen, and uneven gray scale on the display screen of the smart board, you can check whether the cable interface is loose, re-plug the display cable; adjust the resolution setting; try different signal source inputs, etc. Professional maintenance and debugging may also be required.
7. Smartpen Not Working
For the problem that the smart pen cannot write or the handwriting is not smooth, you can replace the battery, check whether the hardware components such as the pen tip and spring are damaged; update the touch driver and the firmware of the pen; if necessary, you can disassemble and clean the inside of the pen.
8. Smart board overheating phenomenon
If the smart board generates a lot of heat, you can check whether the fan vents are blocked and keep ventilation; reduce the brightness of the screen; clean the dust; you can also install an additional cooling fan.
9. Audio issues
If there are audio problems such as audio distortion, noise, and only mono output, you can check whether the audio cable interface is connected correctly, adjust the volume, or try to update the audio-related drivers to solve it.
10. System upgrade failed
If the system is stuck or fails during the system upgrade, resulting in the failure of the smart board to start, you can contact the manufacturer’s technical support and use the backup system restore method to recover.
If the problem is complicated, it is best to let professional maintenance personnel carry out troubleshooting to avoid secondary damage caused by unprofessional operations.
