Check if the saber has been switched to RGB mode. On older firmware, this is done by holding the switch past the point of turning the saber off completely, into deep sleep mode. You will hear an audio cue saying “pixel to RGB” or “RGB to pixel”, meaning that the saber has been turned to baselit mode or pixel blade mode respectively.

If you have a Xeno3Pixel saber, and it has been turned to RGB mode, it does not know how to light the blade up. Simply hold the switch down whilst in standby as if you are going to turn it off into sleep mode, and keep holding it until you hear the saber say “RGB to pixel”

Alternatively, in the config file on the SD (in the settings folder) you can adjust whether the config is set for RGB or Pixel mode.

Finally, in the bluetooth app available on either Android or Apple phones (Xeno Configurator) you can change whether the saber is configured for RGB or Pixel.

You can also factory reset the saber using the app.

If you have enabled “ghost blade” and/or “blaster blade” in your config, then your blade may also act erratically. You can either disable those, or refer to your instructions on how to toggle different blade modes

Check that the saber is charged first (See general troubleshooting guide for more)

Check the SD card is inserted correctly.

Check the SD card has the correct files, in particular in the settings folder (if you see config.tmp but not config.ini, then the files are likely corrupt – contact us with your order number and we can provide the default files)

Finally, it may pay to format the SD and reload the original files back on there (either from your own backup or contact us with your order number and we will send them).  Alternatively, it may mean the SD card has failed.

Check if the saber is in mute mode. Hold the switch until the LED on the switch flashes once, about 0.5 seconds, then release. If you hear an audio cue telling you volume high, volume low, mute each time you do this function, then your sound is working – ensure it is not on mute mode.
