Is it a stand up or a wall mount dartboard?
Step one: Will it turn on? (stand up) if yes go to step two
- If nothing is working verify your AC power cable, (the cable coming from your outlet to the machine) is in good working condition, check for cuts/abrasions/sharp bends/knicks in the wire. If nothing seems out of the ordinary you could then try a different cable. The cable itself is a generic cord and you probably have one lying around somewhere, unlike your cell phone chargers which are not at all interchangeable.
Step two: Will it boot up? (stand up)
- In older standup dartboards like the galaxy 1 or "bull shooter", a lot of times if it will not boot up or keeps resetting it is because the contacts get dirty over time. Carefully disconnect the main and or secondary line voltage feeds going from the power supply to the motherboard. be sure to slowly pull the connector(s) from both sides as to not bend the small fragile prongs behind it.
- Then, using a very fine sandpaper, were talking something smooth to the touch, such as 1000 grit or a piece of standard 8''/11'' copy paper, gently wipe off the contacts. (small metal prongs on the motherboard). There will more than likely be brown carbon residue left on your piece of paper.
Note: You would not want to use something abrasive such as regular sand paper or a file; because you will likely have to do this periodically over the life of your dart board.
Step three: Is the monitor/screen not working?
- Check your connection coming directly from your power supply. there should be plugs, one plug should be going to the monitor while the other goes to the motherboard. try unplugging the cord coming from the monitor and plugging it and checking for defects before plugging it back in.
Step four: connections, connections, connections.
- Follow all your wires coming off or going to the motherboard and the back of the dart board. Anywhere you see can see a plug or connection verify its tight and follow all your wires while scanning for defects. especially with small wires even the tiniest of knicks or exposed copper should be cut and spliced and wrapped in electrical tape to prevent moisture from corroding the connections.
All i can say about wall mounted electric dart boards is they are cheap and can be damaged very easily. Often times if you threw a dart hard enough it would be more than enough to do some permanent damage or cause malfunctions such as no sound or distorted sounds coming from speakers. All I can personally recommend short of taking it apart and looking at everything is going to walmart and buying another one for 30ish dollars.
