How to Fix LED Lights: Step by Step Guide

Share this Article

There are many ways to fix LED lights. We’ll break down how to fix LED lights based on where the problem is coming from and then explain the different ways to fix each problem in each section. Read the content till the end to learn the fixing process of your LED lights!

Find the Root Cause of Your Faulty LED Lights

The first step is to determine why your LED lights are failing. LED light faults are often caused by one of three primary causes: broken bulbs or diodes, blown fuses, and malfunctioning.

Check for Broken Bulbs or Diodes

The most common problem with LED lights is broken or bad bulbs, which are also the hardest and take the most time to figure out. LED lights are tough to fix because the socket, prongs, or diodes are more likely to break than the bulb itself. Since LED light bulbs don’t have filaments that can burn out, they can be harder to find when they break.

Check if LED light Fuses have Blown

The easiest way of finding problem and fix or repair your LED light or bulb is a fuse that has blown. If the whole string of LED lights doesn’t work, it’s probably because a fuse blew (or potentially an outlet problem.) To see if a fuse is blown, look closely at the plug end of the lights. You should see a small hatch that you can open with a safety knife or a screwdriver. Inside, you’ll find two fuses; if either is burned out, your lights won’t work.

How to Fix LED Lights?

If you can not fix your LED light strip by finding the root causes, your LED light may malfunctioning. When there is a bad connection or wiring between two parts of a LED light strip, the light strip won’t work.

These bad connections can stop the flow of electricity and turn off other strips that are connected to the bad one.

The best way to fix this problem is to switch the broken strip to a new one. This guide will show you how to replace your broken light strips gradually.

You will learn to tell which strip needs to be changed and how to take it off the still-working strip. You will also learn how to replace and reconnect the two working strips, so they are secure and work properly.

The strips will be reconnected by soldering the connections of the two still working together.

Find where the lights fail to work and where there are four connections marked “12V, R, G, B” in descending order with a “cut here” mark and a copper-colored backing.

Cut along the “cut here” line with scissors to separate the bad strip from the good one. If your LED strip lights do not work after cutting, you can read this! And if you want to know where you actually should cut, then you should click here!

Process: Three

Align the new strip with the already used strip and hold them both steady. Look at the four connections as if they were the other way around. R goes to R, G goes to G, and so on. You can put solder on all four connections in any order. Make sure that the solder is in place and stable.

Once the four connections are securely soldered, plug the strip in and turn on all three colors of lights to make sure the connections are still strong. You can now put the lights where you want.

Final Words

Before we talk about finding and fixing problems with your LED Christmas lights, we want to remind you that holiday lights can be dangerous when plugged into an electrical socket, especially if the wires are broken. If you touch or cut a live wire, you could get an electric shock, get burned, or even die. Don’t try to cut or fix an LED light while it’s still plugged into an outlet.
