How to Fix a Broken Led Strip

This Instructable will show you how to fix a broken LED strip. The first thing you need to do is find the break in the strip. To do this, plug in your LED strip and turn it on. Then, slowly move your hand along the strip until you find the break. Once you find the break, mark it with a piece of tape so you can easily find it later.

Summary: Fixing a broken LED strip can be a little bit tricky, but with a little know-how and a few tools, it’s not too difficult. First, remove the damaged strip by gently pulling it out of the housing. Then, use a flat head screwdriver to pry up the adhesive backing, and peel it off the LED strip. Finally, use a razor blade or a utility knife to cut the old adhesive off the new LED strip, and then press it firmly onto the housing.

What Causes a Broken Led Strip?

Many things can cause a LED strip to break. Some of the most common causes are listed below:

Water Damage:

If a LED strip gets wet, it can short circuit and stop working. Water can also cause the adhesive holding the strip in place to fail, causing the strip to fall off.


LED strips are flexible, but they will be damaged if they are bent too much. Bending them at too sharp of an angle can result in the internal wires breaking, which will cause the LEDs to stop working. Try to avoid bending the strips more than 90 degrees.


Use a Fan to
 Cool the Strip

If a LED strip gets too hot, it can be damaged. Heat can cause the adhesive to fail, causing the strip to fall off. It can also cause the LEDs to fail. If your LED strip is getting too hot, there are a few things you can do to prevent damage:

  • Use a lower power setting. This will help to prevent the strip from getting too hot.
  • Use a shorter strip. This will help to dissipate the heat more effectively.
  • Use a larger heatsink. This will help to keep the strip cooler.
  • Use a fan to cool the strip. This will help to keep the strip cooler and will also help to prevent the adhesive from failing.

Physical Damage:

If a LED strip is hit or crushed, it can be damaged. This type of damage is often irreparable and can render the LED unusable. Physical damage can occur in several ways, such as:

  • Hitting or crushing the LED
  • Puncturing the LED
  • Folding or creasing the LED
  • Applying too much pressure to the LED
Physical Damage Can Occur in Several Ways

Tools & Materials Required:

  • LED strip
  • Tape
  • Wire cutters
  • Wire strippers
  • Soldering iron
  • Solder
  • Heat shrink tubing (optional)
  • Electrical tape (optional)
  • Multimeter (optional)

10 Easy Methods – How to Fix a Broken Led Strip:

1. Check Your Power Supply

The first step in troubleshooting a broken LED strip is to check your power supply. Make sure that it is plugged in and turned on. If it is not plugged in, plug it in and turn it on. If it is plugged in but not turned on, turn it on.

2. Check the Connection Between the Power Supply and the LED Strip

If the LED strip is not lighting up, it may not be receiving power. First, check the connection between the power supply and the LED strip to make sure it is secure. If the connection is loose, tighten it. If the connection is damaged, you may need to replace the power supply or the LED strip.

3. Check the Fuse

If the LED strip is not working, check the fuse to see if it is blown. If the fuse is blown, replace it with a new one. You can use a multimeter to test the fuse to see if it is blown. Fuse ratings are usually printed on the side of the fuse.

4. Check for Loose Wires

If the LED strip is not receiving power, the problem may be loose wires. Check all of the connections and make sure that they are secure. If you find any loose wires, tighten them up and see if that fixes the problem. Use electrical tape to secure any loose connections.

5. Try a Different Power Supply

If the LED strip still isn’t working, the problem may be with the power supply. Try using a different power supply, and if that doesn’t work, check the voltage rating on the power supply to make sure it’s compatible with the LED strip. If you’re using a 12V power supply, ensure the voltage rating is at least 12V. If you’re using a 24V power supply, make sure the voltage rating is at least 24V. If you’re using a 1A power supply, make sure the current rating is at least 1A. If you’re using a 2A power supply, make sure the current rating is at least 2A.

6. Check the LEDs

If the LED strip is not lighting up, the problem may be with the LEDs. Check to see if all of the LEDs are in working order. If even one LED is not working, the whole strip will not work. Use a multimeter to check if the LEDs are receiving power. If they are, then the problem may be with the soldering.

7. Check the Soldering

If the lights are not working, it may be because the connections are not secure. Check all of the connections to make sure they are tight. If any of them are loose, you can try soldering them again. Use a multimeter to check for continuity between the positive and negative leads on the strip. If there is no continuity, then the connection is not complete and needs to be fixed.

8. Replace the Driver Chip

If the LEDs are still not working, the problem may be with the driver chip. This chip controls the current going to the LEDs. To replace the driver chip, you will need to solder a new one in place of the old one. You can purchase replacement driver chips online or at an electronics store.

9. Replace the Damaged LED

If one of the LEDs is not working, you can try replacing it with a new one. You will need to find the damaged LED and remove it from the strip to do this. Then, solder a new LED in its place. Once the new LED is in place, test the strip to see if it is working properly.

10. Call a Professional

If you have tried all of these troubleshooting tips and the LED strip still isn’t working, you may need to call a professional. An electrician or lighting technician will be able to diagnose the problem and make the necessary repairs.

How Long Does Led Strip Light Last?

The answer to how long LED strip light lasts is that it depends on many factors. The lifespan of an LED is around 50,000 hours, so in theory, your LED strip lights should last a very long time. However, other factors can affect the lifespan of your LED strip lights, such as how often you use them, how well you take care of them, and what type of LED strip lights you have.

  • The quality of the LED strips. Cheap LED strips are more likely to fail prematurely than high-quality ones.
  • How often do you use LED strip lights? If you use them all the time, they will inevitably wear out faster than if you only use them occasionally.
  • How well do you take care of the LED strip lights? If you store them properly and don’t expose them to excessive heat or moisture, they will last longer.

With all that said, if you take care of your LED strip lights and don’t use them excessively, you can expect them to last several years. So, if your LED strip lights have stopped working, it’s likely due to one of the other factors mentioned above and not because the LEDs themselves have failed.
