Troubleshooting

The following are some assistance tips for identifying and resolving electrical problems.

The Display Does Not Power Up

Make sure you fully charge the battery for six to eight hours before your first-time use. The LED's on
the charger should be green when the battery is fully charged.
If your display still does not turn on, please check the wires and the battery, please make sure the
connections are not loose and that the battery is installed in place and fully engaged into the locking
mechanism. Press the M button and hold it for three seconds.
If it is still not working, you will need to get a voltmeter, and do some testing.
1. Turn on the power button, then test the battery output voltage (Figure 7.1).
If the voltage is 0, it means there is something wrong with the battery output plug, cell or fuse,
please take a picture or make a video to show your test results, then send it to us.
If the battery voltage is not zero but less than 32 volts, please fully charge the battery for six to
eight hours, then test again. If the battery voltage is between 32 and 42 volts, but the display
cannot power up, it means that the battery is good. Next, we should test the other two plugs.
2. Open the controller box, and find the power wire (it is black and red) that connect the battery
and the controller (Figure 7.2).
Test the voltage of the power wire, if it is 0, it means the power wire needs to be replaced.
Please take a picture, send the photo to us. If the voltage is the same as the battery, it means
the power wires are good, and we now need to test the output voltage of the controller which is
the plug that connects the controller and display. It has five wires on the plug.
3. Test the red and black wires (Figure 7.3).
If the voltage is 0, it means the controller needs to be replaced, if the voltage is the same as the battery,
it means that the display needs to be replaced, please take some photos and send them to us.
Following the steps noted here will go a long way in helping us solve your issue in a timely manner.
