Common Issues with LED Screens

Display is out of order

If the screen looks like a mixed up puzzle, then the issue is that the LED processor doesn't know what order to put the panels in. You will need to upload a new map from the laptop to the LED processor with the USB cable. See the LED Processor section for more info

Panels are black

If an entire panel box is black, or several rows are out check the following items in this order:

  1. Ethernet cables are most likely going bad, check the cables on the first and last dead panel. See the LED Data Issues page

  2. Power supply could be dead. Make sure LED lights on the send cards show that it is receiving power from the power supply. See the Power Supplies page

  3. Sending card could be going bad, its very rare but you can plug a new one in fairly quickly by switching ribbon cables, Ethernet, and power cables to a new sending card before unscrewing the old one from the case. See the Sending Cards page

  4. If no lights are on, check the power cable and breakers.

Individual panels failing

If one color is failing, or if a row of individual panels in a box is failing, then it is most likely just an individual panel that is going bad. Because the LEDs are chained together, if one fails then the next LEDs in the series may also be experiencing problems. Replace the first panel in the chain that is going bad, then the next should work. In the example to the right, one panel had the RED computer chip die, and then the LED panel next to it also experience the same color issue because the first one was not passing the data down the chain correctly.

Part of Screen is cut off

If part of the image is cut off, you can usually fix the issue by just selecting the "SCALE" button on the LED processor. If this does not work you may need to reset the controller to factor setting and upload a new configuration map from the laptop.

NOTE: It is normal for the screen to cut of a little bit of the image around the sides as the processor, video switcher, or laptop attempts to resize the image to fit the screen.
