LED strip lights are one of the popular options for lighting spaces. But sometimes they have some problems. In this article, we’ll take a look at how to repair broken LED strip lights and troubleshoot to make sure they’re glowing again. Read on to discover common problems and effective solutions.

When LED Strip Lights are Broken, How to Repair it?

When it is found that the LED strip lights are broken, the main performance is that it does not light up. So, when the LED does not light up, we need to troubleshoot the problem before repair it.

Check the Connection

When it is found that the LED strip lights are broken, it needs to be powered off first. Double-check all connections and make sure they are secure and properly aligned. In particular, check where connectors or soldering are used to see if there is any looseness.

Check the LED strip lights Connection

Power Problem

Check the voltage and power of the power supply to see if it is compatible with the LED strip you are using. Then is the power of the power supply enough to run and so on. Also, test the power supply with another working device.

Overheating LED Strip Lights

You can touch the LED strip lights lightly to see if it is a little hot. You’ll need accessories to aid cooling, if any. Also, make sure the LED strip lights are installed in a place with proper ventilation.

Incorrect Polarity

Connecting the wrong positive and negative poles is a common failure problem. You need to see the positive and negative poles, then connect and make sure the polarity is correct. Reversing the polarity can easily cause a short circuit and break the LED strip lights.

LEDs Broken

If one of the LEDs does not light up, it is a malfunction. You will need to replace the damaged LED with a new one of the same specification. But if you want to do it yourself, I suggest that you can directly cut this section of LED strip, and then solder it.

Moisture Damage

Depending on the installation environment, it must be dry and ventilated. Make sure the LED strip lights are well sealed. If you need to install the LED strip lights in a damp place, then you need to choose waterproof LED strip lights.

12 LED Strip Lights Broken Problems- Common Troubleshooting

When we encounter the situation that the LED strip lights do not light up, don’t panic. First of all, calm down, and then troubleshoot the LED strip lights broken problem, and repair it directly. The following are some problems that often occur with LED strip lights. If you encounter such problems, they can be used for your reference.

12 LED Strip Lights Broken Problems- Common Troubleshooting

1: The LED strips are not all turned on.

  • Solution: You need to turn on all the light strips to check the power supply and connection. Make sure the power supply is working and all connections are secure.

2: The LED strip lights flicker or dim.

  • Solution: Once LED strip lights flickering is found, it needs to be disconnected immediately to avoid damage. Check again for loose or wrong connections. And check that the power supply is providing the correct voltage and current.

3: The brightness on the LED strip is uneven.

  • Solution: Check for damaged or burned LEDs. If not, it may be that the power supply is insufficient, and you need to check whether the power of the power supply is large enough.

4: The LED strip is humming.

  • Solution: First check whether the accessories are compatible. Check again for the sound coming from there. Our recommendation is a higher quality power supply to reduce electrical noise.

5: The LED strip is overheating.

  • Solution: Be sure to install the LED strip lights in a dry and ventilated place. There are also appropriate accessories for heat dissipation, and overheated LED strips are prone to failure. Also, reduce the load on the belt by using multiple power supplies or shorter segments.

6: The LED strip is not sticking in place.

  • Solution: If the LED light strip is not pasted smoothly, the light and brightness emitted will be uneven. So, you need to clean the surface where the LED strip is installed again and fix the strip in place with the mounting clips.

7: The LED strip is emitting the wrong color.

  • Solution: Check the connection cable, and whether the color is correct. And make sure the RGB or color control settings are configured correctly.

8: The LED strip remote is not working.

  • Solution: first try to replace the remote-control battery. Then check if there is any obstacle between the remote control and the LED controller blocking the connection.
  • Solution: You need to check the LED controller first, and then reset the LED controller to its default settings. In addition, re-control detection.

10: The LED strips are not dimming properly.

  • Solution: First confirm whether the LED strip supports the dimming function. Then verify that the LED controller supports dimming. Check the compatibility between the controller and the LED strip.

11: LED strips are showing signs of fading.

  • Solution: This is a normal phenomenon; LED strips will age slowly over time. Check the LEDs for signs of aging and note how long they have been used. Let’s see if it is normal aging or failure.

12: The LED strip lights do not work after a power outage.

  • Solution: You need to check the link connection, and then reset the LED controller and power supply. Inspect the light bar for any visible damage and replace any faulty components.


Finally, if the LED strip lights are broken, you also know how to repair them. We need to troubleshoot the problems one by one, and then adopt corresponding solutions. Remember, it is recommended that you consult a professional if you are not sure that repairs of the broken LED strip lights are possible for you. If you have any problems with the LED strip lights you purchased, please let us know.


How to fix a LED strip that won’t light up?

First, we have to check that the LED strip lights are all on. Then check the connection, the voltage and the power of the power supply to ensure that the connection is correct.

What should I do if the LED strip lights flick?

You need to cut off the power first, and then check whether the connection is loose. Make sure the power supply you purchase is adequate and compliant, and consider using an LED-compatible dimmer.

What if my LED strip lights are overheating?

Generally, insufficient heat dissipation, excessive power, or excessive load will cause the light bar to overheat. You need to install the LED light bar in a place with ventilation and heat dissipation. Also, reduce the load or use an LED heat sink.

How do I repair an LED strip with fading issues?

If over time, the lifespan of the LED light strip is coming to an end. You need to judge, and then replace the damaged LED strip, or directly replace the new LED strip.

How to repair LED strips with damaged LEDs?

You can just cut the unlit section of the LED strip lights. The wires are then spliced together using connectors or soldering to ensure proper insulation.
