How to fix my Kamvas 13 no signal black screen problem?Updated a year ago

Having issues with your Kamvas 13?


Here are some of the most commons issues and the steps to solve them:

  1. No signal or flash screen issue:
    • The reason your tablet shows no signal or the screen is flashing when connected to your computer or phone may be due to insufficient power supply.
    • To solve this issue, connect your tablet to an external 5V power supply or by using a 3-in-1 5V power supply.

      5V Power Supply:
      3-in-1 5V Power Supply:
  2. When the red USB-A end of the 3-in-1 cable is connected to a 5V power supply but the logo does not appear and the LED light around the tablet's power button will not turn on:
    • Connect the USB-C end of your 3-in-1 cable to the lower USB-C port on your tablet (the port that is supposedly for the USB-C to USB-C cable) and check if the logo appears and if the tablet's LED light will turn on to confirm whether the 3-in-1 cable power supply is working.
      1. If the logo will not appear and the power button's LED light will not turn on, then the issue is with the 3-in-1 cable. Thus, the 3-in-1 cable needs to be replaced.
      2. If the logo appears and the power button's LED light will turn on, it means that the upper USB-C port of the tablet is not working. Thus, the tablet needs to be replaced.
  3. When the red USB-A end of the 3-in-1 cable is connected to a 5V power supply but a "no signal" error appears:
    • Confirm whether the computer's HDMI port works normally by connecting other monitors to the said port If the other monitors work fine, the 3-in-1 cable may be broken and needs to be replaced.
    • If in case the new 3-in-1 cable still results in a "no signal issue", then the tablet's USB-C port is damaged so the tablet needs to be replaced.
  4. When the Kamvas 13 is connected to the computer a "USB Device Cannot Be Recognized" error appears (as shown below):
    1. This error may be caused by an insufficient power supply. The red USB-A end of the 3-in-1 cable can be connected to a 5V power supply to resolve this issue.
