Verify LED Module is receiving power
- Remove the screws holding the LED Module onto the Ticker Cabinet.
- Once all screws have been removed, gently pull the LED Module away from the Ticker Cabinet
- Locate the power light indicator on the back of the LED Module, it will be near the center, above the red and black power cable plugged into the Module.
- If the power light indicator is OFF, and assuming the power light indicator for other LED Modules is ON, the LED Module is not receiving power. Your next step would be to validate the applicable Power Supply is outputting the proper voltage.
- If the power light indicator is ON, your next step is to troubleshoot and determine if the LED Module is faulty, the CAT5 connecting to the upstream LED Module is faulty, or the upstream LED Module is faulty.
Test power output from Power Supply to LED Module
- Using a multimeter, check the output from the Power Supply by checking the same terminals connected to the LED Module.
- Proper voltage output should be 5v DC.
Steps to isolate failure point when LED Module is receiving power
Content scrolls on an LED Ticker from right to left as you are facing the Ticker. Using a water flowing in a river as an analogy, water that has already passed where I am standing by the river is “downstream”. Water coming towards me is “upstream”. Content scrolling on a Ticker works the same way - it flows from one module to another via a CAT5 interconnection between LED Modules.
Using the diagram below as an example, Module #1 is upstream to Modules #2, #3 and #4. Module #3 is upstream only to Module #4, etc.
As an example, if content was scrolling on Module #1 and Module #2, but not Module #3, you could have one of the following problems.
- Bad output on Module #2
- Bad or loose CAT5 interconnect between Module #2 and Module #3
- Bad input on Module #3
In no particular order, here are steps you can take to isolate the cause.
- Swap Module #3 with a known working upstream Module. In this example, Module #2 would be the easiest.
- Replace the CAT5 between the Module not showing content and the Module directly next to it upstream.
If you determine the LED Module is faulty, reinstall it as the last LED Module on the Ticker (Module #4 in the example above), if you don’t have a replacement.
