If your Proton will not turn on, check for these issues:
Is the battery dead or too low to turn the marker on?
Is the power button fully depressing the microswitch? The button should smoothly go in and stay in place.
Is there any damage or corrosion to any of the electronics? Carefully remove and inspect the battery board, battery wire, main board, sensor board, flex wire, and solenoid for any damage or corrosion. Confirm the microswitch on the sensor board still smoothly clicks.
If the marker is still not working properly contact Valken customer support. Please open a ticket with our customer service department. To open a ticket, please click on the chat button on the bottom of this website and our customer service representative will be happy to assist you.
