As long as the marker is working like normal. Then I would say that the only problem is the OLED screen is "JACKED". We can send you a replacement board if you would like or we can have you send everything sent to us for repair. Please email us at email@example.com
with the following;
Requesting Board or RMA for repair.
Once we have that im sure we can get it fixed and get you back to playing ASAP.
