Condition Possible Causes How to Fix
Black BrightSign Screen
BrightSign logo with other WiFi/wired
information is shown on screen.
MicroSD is missing or not
fully inserted.
Confirm USB is present and fully inserted.
MicroSD format or
content is incorrect.
1. If the door content was just updated, this could be
the cause. Verify that the USB was updated following
the correct formatting guidelines (see Section 7.8).
Otherwise, it is unlikely unless the USB has failed. The
USB and content can be verified several ways:
• The door can be unlocked by touching the corners
of the video area (even though no video is present).
This will present the normal controls. Attempting
to cycle content could display the content.
• If available in the menu, the Test for Content button
can be used to check for anything on the USB.
• The USB can also be checked by connecting to
a computer and verifying the folder names and
presence of files.
2. Confirm presence and remove/reinsert then power
door again.
3. Verify software number on microSD and report to
Technical Support.
