Working within an LED display without proper precautions can cause damage to the display, injury or death due to electric shock to someone not taking proper precautions. Power display off while performing any service and only power back on to view results. Be sure to use proper grounding techniques to avoid electric and static charge to the internal components.
Is your display getting appropriate power? It is critical to verify that the input power is proper & not under delivering, proper grounding is provided.
1. Playlist is sent properly
2. Side one and side two are included
3. File being sent is not corrupt
4. Screen setting not changed
Many times you can open an older playlist to send to verify that the playlist is not the issue.
Several reasons cause your computer to not communicate with the display. Most times this is corrected by powering off the sign for 30 seconds & powering back on from the main panel.
1. Is your sign turned on
2. Has computer IP address changed
3. Is there a conflict with your wifi IP
4. Transmitter faulty, check indicator lights
5. Software settings changed
On a double sided display, if the second side is not working, many times it is the playlist configuration. You can test by opening an older playlist that has worked and try to send to see if this corrects the issue.
1. Proper power to second side
2. Is network jumper cable damaged
3. Is the playlist properly formatted
4. Any damage to the receiving cards
This image illustrates a fully working screen. Also showing the Modules, Ribbon Jumpers between each Module, the Receiving Hub Card, and the Main Ribbons from the Receiving Hub Card to the starting Modules.
This configuration is typical of all LED displays. There may be additional components and left right justification might also be reversed. This illustration should help you understand the order.
Illustration shows 4 modules not working.
A. First check the Flat Ribbon Jumper wire between modules R2C4 & R2C5. Make sure it is seated properly. Replace the ribbon wire to be sure.
B. Make sure Module R2C5 is receiving proper power. Correct power must be between 4.6V and 5.4V for the module to work properly.
C. Exchange module R2C4 with R2C8. If this corrects the issue, module R2C4 has a bad output and placing it at the end solves the issue.
D. Exchange module R2C5 with R2C8. If this pushes the issue to the end, module has a bad input and must be replaced.
Illustration shows an entire section not working.
This is a good indication that this is a power issue.
1. Verify power to power supply is 110V.
2. Verify all leads coming to the power supply are properly seated.
3. Power supply output must read between 4.6V and 5.4V. Verify all leads are crimped properly and there are no loose connections.
4. If the output is reading very low, replace the power supply.
