How to Troubleshoot LED Signs

Check the problems of your signs; calling a technician may not be necessary.

How to Troubleshoot LED Signs | Affordable LED

LEDs are known to emit a very bright light compared to traditional fluorescent and HPS lighting. And even if they give off such brightness, the power usage remains low, which is why many are making the switch to LEDs. However, there might come a time when your shop’s open sign may not be as bright as it was before or is frequently shutting down. No worries, it could just be a problem with the power.
Don’t call a technician just yet; let us help you troubleshoot your LED sign by asking yourself these five questions:

Have I checked the main power source?

First things first -- check is the main source of power. The problem might be with the source itself, and if that’s the case, your sign is probably working just fine. As a solution, find a new source in the meantime. If there is none, you can opt to use a generator or a portable power supply while the main source is being repaired.


Have I checked the connections?

Sometimes, the problem is simply with loose connections. It is a no-brainer that electrical connections should be tight and secure to properly function. That is why it is important to check during initial installation if the wires are connected tightly. Loose connections not only cause problems with receiving power but also cause the unit to overheat. Regularly check the connections to prevent issues such as fire hazards.


Is the sign’s electrical wire too long?

If your sign’s electrical wire is too long and is far from the main power source, there’s a big chance that the voltage has dropped. This is because the electricity might be having difficulties with traveling through long wires because of resistance and this causes the voltage to drop. Not only will it not light up the sign, but a low voltage can also be detrimental to the internal components of your unit. Find a nearer power source so you won’t need to use long electrical wires.

Are the wires of the correct size?

The size of the wire is also an important factor to consider. If it’s too small, electricity won’t be able to travel properly and won’t be able to meet the power requirements of the sign. This then can damage the internal components through overheating and voltage drop. Should you need to use extension cords, make sure to use ones that are for heavy-duty use.


Is the system voltage enough to power up the sign?

So you found a new power source, but the sign still won’t light up. This time, check if the system voltage is compatible with your unit. Most units work on 120 or 230 volts or within a 10% range like at 115 or 220. Do remember that it must stay within that range; otherwise, your unit might get damaged. As an example, a sign that runs on 120 volts cannot run on 230.
