Pens do not work at all. The flame is white and does not change color when the pen is hovered over it. I have updated the driver, unplugged from the wall and the USB, and still no success. The serial number is C0909301925. I do have sound from the speakers.
Do these pens work fine with other boards of the same model?
Can you calibrate the board?
Also, perform a power reset as per below:
– Disconnect the USB cable from the computer
– Switch off the stand by button on the left hand side of the board so it goes red
– Connect the USB cable to the computer and check if the LED on the top left corner comes on
– Then switch on the stand by button on the left handside
