Device Won’t Turn On
We will now troubleshoot what is causing your device to not turn on
Test Your AC Jack
Using a multi-meter set on DC in the 12V range, touch the red prong to the prong inside the jack and the black on the outer shell inside the jack. It should read the proper voltage if working. If not, desolder the jack and replace it with another.
Test Your Switch
Disassemble the device. Then put multi-meter on the terminals of the switch. It should read the proper voltage if the part is working. If not, desolder the component and replace it.
Device Won’t Feed the Money
We will check to see why the money is not going in
If no noise is made, the motor may not be secured in the plug correctly. If so, push it together until it clicks into place. The wire attaching the motor to the board may be disconnected as well. If so, solder the wire back onto the board.
Check Motor Band
If a noise is being made, the belt for the motor assembly may be broken. If so, replace the part.
Can’t See the Display
If the device is turned on and it beeps but the display does not work—here is what to do.
Check Display Connector
Check to see if the display is connected properly. If it is connected, but still not working replace the display board.
