CHECK THE POWER:
This may signify that your power is OFF - the most common cause of a Black screen is usually due to power surges and/or accidental power off from the mains - please check that power to the unit has not been affected. If you are able to safely restart power from your mains - please do so, and simply wait 5 minutes - your product is programmed to then reboot.
In the unusual instance that this has not worked please take a photo or video and email us at [email protected] we will contact you and resolve.
Safety Note: If rebooting from the mains does NOT work, DO NOT individually start turning items on/off and reconnecting, by doing so, you may permanently damage your product and void all warranties.
