How To Fix Broken LED Light Strips

In any event, LED lights are a fantastic way to brighten up your room. Lights add a distinct type of joy to our lives, and when your LED lights stop operating, they can ruin your mood. As a result, we’ve prepared detailed instructions on how to fix broken LED light strips. 

When there is a broken connection or faulty wiring between two pieces of the strips, they will collapse. These bad connections can obstruct power flow and cause other working strips connected to the faulty strip to turn off.

Replacing the problematic piece with a new functional strip is the best way to solve this problem. This article will show you how to fix your faulty light strips step by step. 

You’ll learn how to recognize which strip has to be replaced and how to separate it from the functional strip. You’ll also learn how to properly secure and rejoin the two functional strips by replacing and reconnecting them.

Things You’ll Need

  • Extra LED strips
  • LED Shim 
  • Soldering Iron + Solder
  • Clippers
  • Heat Gun or Lighter
  • Xacto Knife or Scissors

Not necessarily you will need all these items because your issue can be one and you might just a few things from this list above.

A Stepwise Guide On How To Fix Broken LED Light Strips

Step 1: Identify The Cause

The first step in repairing your broken LED light strip is to determine what is causing your lights to stop operating. As a result, take a close look at the strip to see whether there are any obvious flaws.

Step 2: Check The Strip And Repair

Find the area where the lights cease working and there are four connections labeled on the strip so cut off the part where the “cut here” sign is marked using a scissor. The problematic strip will be separated from the working strip by cutting along the “cut here” line. 

Make sure the new strip is parallel to the working strip and that they are both stable. Take a look at the four connections in reverse order. For instance, R to R, G to G, and so on. Apply solder to all four connections in any sequence. Verify that the solder is secure and stable. Plug in the strip and switch the lights to all the colors once the four connections are soldered tightly. You can now arrange the lights wherever you want.

Note: If the strips had an adhesive backing, you might need to get some new adhesive. Use an acetone-soaked cloth or a citrus-based cleaner to remove the adhesive residue off the back of the strips without damaging them. Ensure that the liquid does not come into contact with the LEDs, since this will result in water damage and a reduction in the strips’ efficiency.

Allow a layer of double-sided tape to dry on the backs of your LEDs before putting a layer of double-sided tape, wiping the surface with rubbing alcohol, and relocating the LED.

Step 3: Check The Power Supply

Multiply the length of your LED strip in feet by the watts generated per foot and multiply by 1.2. This will determine the minimum power supply size required to run your strips. Because power supplies come in a variety of wattages, you’ll take the figure you came up with and look for the nearest power supply with a higher wattage rating. For example, if your calculation shows 70 watts then you might need a power supply of 90 watts at least.

Step 4: Change The power supply

Therefore, if your LED lights have stopped working due to overheating then you might consider replacing your power supply with higher watts.

Step 5: Check The Voltage

Another noticeable thing to look at is the power supply you select is compatible with the voltage of your LED strip lighting. So, double-check that the power supply’s input voltage matches the voltage at the place where it will be used. If you want to utilize a 12-volt DC LED strip then you’ll use a power supply that accepts 120 volts as an input and output and has a 12-volt DC output.

Voltage drop is another element to consider during longer runs. After a given distance of the LED strip, there is a substantial voltage drop. There will be insufficient voltage to light the following length of the strip after such distance. This depends on the sort of strip and also its length you are using.

Step 6: Check The Connector

One of the main reasons for broken led light strips can be loose or wrong connectors. Therefore, first, check the connector carefully and make sure you are using the required pin connector for your LED lights because a simple white LED light strip has two pins, you’ll need a two-pin connector. If your RGB strip lights have four pins, ensure the strip connections you buy have the same four pins. Simply place your tape under the contact pads and press down until you hear it click, then repeat the process all the way around.

The LED light should work without a hitch if the contact pads are carefully inserted with the tape. Insert the strip into the connector with attention. Make sure the strip is positioned beneath the ridges on both sides. Make no attempt to force the strip into the connector using any tools.

Step 7: Fix The LED Strips

In order to fix broken led light strips, you need to Insert the strip into the connector with attention. Make sure the strip is positioned beneath the ridges on both sides. Make no attempt to force the strip into the connector using any tools.

Step 8: Test It

A multimeter with a diode setting is required to test LED lights. Connect the multimeter’s negative lead to the LED’s cathode (negative) lead. The red and black test leads should be plugged into the multimeter’s front outlets. The positive charge is represented by the red lead.

The black lead is negative and should be connected to the “COM” input. The LED should shine softly when it’s turned on, showing that it’s functional. Replace the connection to the LED leads if the LED does not illuminate. If the LED still does not light, it is defective.

Tip

For your convenience, all of the LED strips come with pre-marked cut lines. If you’re using waterproof LED light strips, make sure to cover the cut end with an end cap to keep it away from water.

Warnings

Low-voltage DC electronics are typically thought to be harmless and represent a low risk of shock. However, we highly suggest that you turn off or unplug the power source before testing or adjusting any LED strips or accessories, if possible.

Precautions

The strips are safe as long as the cut ends are covered and sealed, stray wires are kept out of reach, and any little unwanted parts are appropriately disposed of.
