How to fix a broken LED strip?

Damage to a light strip is rather uncommon. They can withstand a lot of abrasion and damage.

However, if under enough strain over time, they may tear, malfunction, or fail.

Additionally, one of the main causes of light strip failure is bending or crimping light strips around corners without the correct connections.

However, this is a rather simple remedy as most LED light strips can be clipped.

  1. Detect the damaged region.
  2. Cut the light-strip power.
  3. If possible use scissors to cut the adhered lights off.
  4. Use scissors to cut along the copper markings to remove the damaged area.
  5. Slice a fresh piece of the same LED strip from a new or leftover roll.
  6. Put pin connectors back-to-back on each part of the light strip with the help of soldering iron.
  7. Connect the strip with the other working strips using a soldering iron.
  8. Use the correct number of connector pins (2, 4, or 5 as appropriate).
  9. Try out your LED strip lights and try again on the surface.

Why did my LED lights stop working?

There are several reasons why LED strip lights might stop functioning. The following are some typical causes of the problem.

Power supply

One of the most frequent causes of light strip failure is a power supply issue.

Verify the light’s connection to the power supplies, such as an outlet or batteries, to ensure that it is secure.

Make sure that the power source is operating properly and supplying the required power flow voltage.

Faulty wiring or broken connection

Check the wire connections to prevent faulty connections between the LED light strip and the power supply for any issues.

The electricity flow might be impeded by loose, harmed, or disconnected wires, which will prohibit the entire strip lights from working properly.

Look for any obvious evidence of damage, such as frayed or broken wires, and make the necessary repairs or replacements.

These problematic connections may restrict the flow of power and turn off another connected faulty strip. After switching the multimeter to DC voltage, place the probes on the positive and negative terminals of the light strips.

Test voltage

To prevent a voltage drop, turn off the power source to your LED strip before checking the voltage. You need a multimeter to check the voltage.

Burned-out LED Bulbs

The bulbs of LED strip lights have a limited lifespan, just like regular light bulbs do.

The LED strip lights themselves have likely burned out if several LED lights have stopped working properly. New bulbs of LED lights should be used instead of the old ones, making sure they are compatible with the light fixture.

If LED light strips are not properly constructed or ventilated, they may become too hot.

Excessive heat might harm the LED light strips internal components and cause them to malfunction or shut off.

Dimmer compatibility

Some LED light strips are not compatible with particular models of dimmer switches.

It is possible that the LED light strips aren’t operating because the dimming system is incompatible if you have installed a dimmer switch or made other changes to your lighting arrangement.

Defective components

On occasion, LED light strips may have production flaws or faulty parts that prevent them from operating.

Can you fix broken LED lights?

Depending on the type and severity of the damage, it may be possible to repair broken LED strip lights in some circumstances. Here are some actions you can do to possibly fix broken LED strip lights:

Check the power supply source

Make sure that the LED light strip is getting the right amount of power by checking the power supply, such as batteries or an outlet.

Make sure that the power supply source is operating properly and providing the required voltage.

Replace batteries

If the LED light strip is powered by batteries, consider using new batteries. Batteries that are weak or low might occasionally be the cause of a power outage.

Inspect the wiring

Examine the connections in the cabling that connect the LED light strip to the power supply. Look for frayed insulation, disconnected connections, or loose or damaged wires. If any problems are discovered, you might be able to fix broken LED light strip using electrical tape or replace the wiring to get everything working again.

Replace the LED light strip Bulb

If the LED light strip has a replaceable bulb, it could be worthwhile to attempt to do so. Make sure that the replacement bulb is right for the light fixture and is placed correctly. This procedure might fix the problem because LED light strip bulbs can occasionally malfunction separately.

Ask for Professional Help

If the steps listed above fail to address the issue or the light strip is physically broken, it might be necessary to ask for professional help. Additional assistance or repair alternatives can be obtained by getting in touch with the manufacturer or a qualified technician.

How to reset the LED strip without a remote control?

Without a remote control, you can use one of the following techniques to reset your lights:

Power source. Using the switch or power source they are connected to, turn them off. Keep them off for a minimum of ten to fifteen seconds. Restart them after that. The lights can frequently be reset and returned to their original settings by performing a simple power cycle.

Manual control button. Some lights include manual control buttons that are located right on the fixture. You can adjust settings without a remote by using these buttons. To determine any possible manual control buttons and their respective purposes, see the user handbook of your lights. To start a reset or switch between modes, press and hold the relevant buttons in the right order.

Circuit breaker reset. Resetting the circuit breaker is one option if the lights are hardwired or connected to one. This should reset the lights. Find the circuit breaker that regulates the lights’ power source, flip it off, wait a moment, and then flip it back on.

App-based control. You might be able to reset your lights using a mobile app if you can control them with one. See if the app has a reset or factory settings restoration option for the lights. To start the reset procedure, adhere to the directions on the app.

Contact the producer. It is advised to contact the manufacturer if none of the aforementioned techniques work or if you are unsure of the precise reset process for your LED strip lights. They can provide you with the appropriate instructions or carry out additional troubleshooting.

Can you reattach LED lights after cutting?

Reattaching LED strips after cutting them is generally not advised because cutting an LED light usually ruins the internal electrical connections and components.

Since LED strips are made to operate as a sealed unit, attempting to reattach or repair them using electrical tape after cutting them might lead to unsafe operation, potential safety risks, or additional damage to your own LED strip lighting.


It is possible to fix a broken LED light strip but, the success and practicality of doing so depends on the type and severity of the damage.

Simple problems like defective wiring, a faulty light strips power source, or burned-out bulbs can frequently be fixed by inspecting connections, changing out parts, or restoring wiring. But more complicated issues or physical harm to the LED lights can call for expert help or the necessity for replacement.

When making repairs to LED lights, it’s crucial to use caution and adhere to safety precautions. Referring to the manufacturer’s instructions and warranty details is also essential because erroneous repairs or alterations might invalidate warranties and endanger safety.

It is advised to seek the assistance of a licensed electrician or get advice from the manufacturer if you are unsure how to fix a broken LED light strip. They can offer professional guidance, guarantee accurate repairs, or facilitate replacements when they are required.

You can improve your chances of getting your broken LED strip light working again and taking advantage of their energy efficiency and extended lifespan by taking the necessary precautions and asking for help when necessary.
