Diagnostics and Troubleshooting 36
A column of the display does not work.
• Check that the ribbon and power cables are plugged into the first module in the row.
• While power is on, look at the back of the first malfunctioning module to see if the
diagnostic LED is off, implying a power input problem.
Entire display fails to work.
• Check the diagnostic LEDs on the controller for Power and Run. (Section 7.2)
• Check the breakers in the building connected to main power source.
• Check the breakers in power termination panel (bottom row, second module from left).
• Check/replace the ribbon cable(s) from the controller to the modules.
• Verify proper use of the software by checking the software manual.
Brightness problems
Display is stuck on bright or dim.
• Check Manual/Auto dimming in Venus 1500 software. The Brightness is typically set to
Automatic. If not, perform the following step:
> In Display Manager/ Diagnostics, change the slide bar and click .
• Check the light sensor cable and wiring for secure connections.
• Check the light sensor lens for obstructions. (top left edge, front of primary cabinet)

Message problems
Blank display is seen after boot-up.
A blank display is normal after the boot-up procedure. When finished, the display will be
blank except for a flashing pixel in the lower right corner. The display is then waiting for a
message to be sent.
LED flashes in the lower right corner.
The flashing pixel indicates that the display is receiving power and waiting for a message to
be sent. Once a message is sent, the flashing pixel should be replaced with the message.
Message only shows up on one side of the display.
Determine if the displays are set up as two primary displays or one primary and one mirror
display. To do this, turn off power, then turn it back on and observe the two display faces.
Make sure that both faces have power.
If the set-up involves two primary displays, one should show “HW001” and the other
“HW002” in the boot-up sequence.
ƒ
Verify that two different addresses are set up for these two primary displays in the
Venus 1500 Administrator.
ƒ Verify that two different addresses are set on the controllers.
ƒ Send a different message to each display separately by clicking on that display name in
the list. Note: With two controllers, messages may not always run synchronously.
If the set-up consists of a primary/mirror display, check the cable running between them.
• Verify that the cable is firmly plugged into both cabinets.
• Check that the cable and plugs are in good condition.
