The lights on the Perfect Stitch system won’t light up when the machine is on.
Ensure lights are engaged
In the Lighting menu, make sure that the white light button is turned on (it will be highlighted green) and the brightness is all the way up.
If you have fluorescent lights and an Android tablet, you have to set the system to Fluorescent Lights for it to function properly. Select the file from the top—Advanced— and check Fluorescent Lights in the bottom right.
Test black light
If you have black lights, turn them on. If the black lights work but the white lights don’t, the handle bar lights are receiving power. You may have a faulty handle bar assembly.
If the black lights do not work, check your connections for the power supply wires and the handle bar wires.
Power supply wires
The handle bar lights are powered by a power supply that is slightly larger than a deck of cards. Depending on your particular machine, the power supply could be mounted inside the machine or in the Control box (PCB Box).
The power supply has two wires attached: one that plugs into the Control Box (PCB Box) that provides the power supply with electricity, and another that connects to the handle bar wire. With the machine turned off, unplug and replug both of these connections. Listen for a click to ensure each wire is properly connected. Turn the machine on and test the lights. If the lights still won’t light up, turn the machine off again.
Inspect the end of each wire for wire damage. Inspect the prongs inside each connector to verify if the prongs are bent or otherwise damaged. Any damaged wires may be the cause of the problem.
With the machine turned off, unplug and reconnect the end of the wire that connects to the handle bar assembly. Inspect the wire and connector for damage. Any damaged wires may be the cause of the problem. Turn the machine on and test the lights.
If the wires and connector have no damage and the lights still won’t light up, you need to check the power supply.
Check the power supply
Turn the machine on. Find the green LED light on the power supply.
If the green LED is lit, the power supply has sufficient electrical current running through it. You may have a faulty wire, or the handle bar assembly may be faulty.
If the green LED is not lit, your power supply is not receiving current. You may have a faulty connection to the PCB Box power board, or you may have a faulty power supply.
