Step 1
Wrap a small piece of electrical tape on each light that isn't working with the lights turned on. This way you can see which LEDs aren't lit.
Step 3
Pull out the first light that is marked with tape from the light fixture. Grasp the LED above the plastic covering and pull it until it releases from the fixture.
Step 4
Take the LED to a lighting supply store and have them give you a match for your exact LED. Buy as many as you need to replace your lights.
Step 5
Insert the plastic and metal end of the LED into the socket you pulled it out of until it is firmly in place. The plastic covering of the lamp should be pointing away from the socket.
Step 1: Identify the LD Light That Doesn't Work
Identify broken LEDs. You can do this easily by powering up your circuit and seeing which bulbs don't light. Generally, replacing faulty bulbs will solve issues with LED circuits and fix broken LED lights. Depending on your circuit, you will need to connect the battery or plug it in.
Step 2: Remove the Broken LEDs
Remove the broken LEDs. You may need a soldering iron to do this, depending on how the LEDs are connected to the wire. In commercial LED light circuits, there may be sockets for each individual lamp, and you can simply pull them out. Note the polarity of the LEDs you remove.
Step 3: Replace the LEDs
Replace the LEDs with lights of similar voltage. LEDs do not need to be matched in voltage by a common and exact resistance value, just a general one. This makes replacing bulbs easier, because you can identify suitable LEDs by their color.
Step 4: Connect Replacement Lamps
Connect your replacement lights as needed. This can differ across types of circuit, and if you've got a set of Christmas lights, the sockets may have varying designs, and your new bulb connectors may have to be bent or otherwise cajoled into the correct shape in order to fix your LED lights.
Step 5: Finish the Fix for Your LED Lights
Check the socket's polarity if a bulb still doesn't work. In some circuits, a socket might be the wrong way around, so even a new bulb won't work. Sockets are made to fit the longer positive connector and the shorter cathode. Across a circuit, the sockets should all be aligned in the same direction. If they are not, you can fix the problem.
Why do LED lights fail?
There are two different metals inside the LED light fixture - the socket contact and the LED lead. When exposed to water (and even oxygen, from which the air we breathe consists), these materials can undergo a chemical reaction that causes corrosion and finally failure of the light bulb. Luckily it's easy to enhance the waterproof characteristics of an outdoor lighting by using some dielectric grease. It will stop the humidity and air from getting into the LED light and consequently prevent the corrosion.
What happens if one bulb is not working?
If the one bulb is not working the whole string fails, so the failed light usually cannot be detected. Thus you'll need to pull out each bulb and successively insert a new one in its place until you find the failed one. Read the user's manual before doing this. Sometimes you may detect the stuck caps.
Can you replace a dimmer switch with a CFL?
However if you have an old dimmer switch, it may not always be compatible with the contemporary LEDs. Try to replace a couple of LED light bulbs with the CFL lights. This will correct load problems and most likely fix the flicker of remaining LEDs. As you can see, most of the problems can be fixed by yourself.
Can water get into LED lights?
In the USA, Canada and most of Europe winter is usually very damp, so the water can get into lighting fixtures. LED outdoor lights are supposed to be sealed, but the assembling is not always perfect. And when water gets into a LED light, it causes corrosion which will obviously ruin the electronics inside. fixing LED lights.
Can you use grease to waterproof outdoor lights?
Luckily it's easy to enhance the waterproof characteristics of an outdoor lighting by using some dielectric grease. It will stop the humidity and air from getting into the LED light and consequently prevent the corrosion.
Can you replace a string light if it fails?
When it comes to LED string lights, it is vital to detect the failed light and replace it as soon as possible. There are two main ways of making string lights - in first case failed bulb will stop the work of the whole string, and in second case the string will still be working but the rest of LED bulbs will be under the higher voltage which may cause additional failures.
Step 1: WARNING: Mains Electricity!
This project involves dealing with mains voltage! Extreme care should be taken if you want to attempt a similar repair. If mishandled, mains electricity can kill you!
Step 2: Diagnose the Problem
I had this LED light mounted in my home and it recently stopped working after a problem I had with a loose ground wire. I already replaced it with a new one but I wanted to see if I can repair this one and use it in my workshop.
Step 3: Try Your Fix
After I removed the leads from the old resistor I’ve inserted the new pair through the same holes and without further inspection I was eager to try the lamp out. I connected it with some jump leads to a mains plug, making sure to isolate all of the jump wires connections for safety.
Step 4: Diagnose and Fix - Again!
I removed the light from the mains connection and continued with further inspection. What caught my attention is this smoothing capacitor that was across the input on the bridge rectifier as it had some discoloration. I removed it from the board and sure enough, the capacitor had a crack on one of its sides.
Step 5: Success!
Sure enough, I had a success. The light started working and even though it looks flickery on camera it produces a nice light in person. I then set to isolate the driver board and proceeded with assembling it back to its case.
How to test if LED chip is faulty?
To test the Failed chip, You simply plug in your LED panel and short each individual LED chip. Shorting a Failed LED chip will cause board to start glowing sans the faulty chip. Other Safer method is to use a small 3v Power source (Like 2x AA batteries) and hook up Thin probles to the output.
What happens if you short out an LED panel?
If all faulty chips have been shorted out, rest of the panel should glow right up. Usually shorting 2~3 chips over the entire count of LED chips will have no detrimental effect. Because the LED panel is wired in series, it will keep the current same across all chips. Your Panel wattage will decrease slightly.
What voltage do LED chips have?
Now the way these LED chips are laid out are usually very simple. All the LEDs have forward voltage of about 3.2V and are connected in Series. Chip boad failures means its just one or two LEDs have failed, causing entire board to not glow.
Introduction
If your LED light strips are malfunctioning, then this guide may be what you need. Light strips malfunction when there is a faulty connection or wiring between two sections of the strips. These faulty connections can hinder the power flow and deactivate other working strips that are connected to the faulty strip.
Step 1 How to Repair LED Strip Lights
Find the spot where the lights stop working and where there are four connections labeled in descending order, "12V, R, G, B" with a scissor "cut here" marking and a copper colored backing.
Step 2
With a scissor, cut along the "cut here" line, separating the faulty strip from the working strip.
Step 3
Align the new strip next to the working strip and keep them steady. Look at the four connections like a mirror image. R to R, G to G, and so on and so forth. Apply solder in any order for all four connections. Make sure solder is secured and steady.
Step 4
A solder and soldering iron are fairly common and easy to acquire at a hardware store. Extra length of lights may be left over from initial use, use these first before buying more in order to lower costs. In order to put the lights back where they originally were, some form of an adhesive agent may need to be utilized.
What to do if your LED lights are completely dark?
If your room is completely dark after turning off the lights, we can put a portable work lights under the fixture to provide ample brightness.
What are the problems with LED lights?

Why do LED lights buzz?
Buzzing is another common problem of LED lighting. If your recessed lights or other LED bulbs product such the annoying hum, it might indicate that you overload the circuit. For instance, if the dimmer is just support 300W LED lights but you connect over 200W luminaires, then buzzing would occur.
Why are my LED flood lights not bright?
If the LED is not working in the rated voltage & current , then the LED lights cannot reach the maximum brightness. When buying the LED lights from manufacturer and you wish to use your own driver, you need to clearly know what is the power, voltage and current input of the LEDs. If the power rating of the driver does not match that of LED, the flood light bulbs will not be bright, or even burnt out. Therefore, it is highly recommended to adopt the original setting of the whole LED lights.
What does glare mean on a TV?
Glare means the strong blinding lights coming out from the light source. It can blur our vision and affect our living quality. For instance, it would be very difficult to read the words on the magazine due to the reflection. Also, white reflective glare of the lights will create white spot on the TV screen.
How to know if LED bulbs are dimmable?
Firstly, we need to check if the bulb is dimmable. Before you buy the LEDs, you can clearly see the bulb is stated as “dimmable” if they are. If you connect a dimmer switch to non-dimmable LED bulbs, it will usually remain 100% on, no matter how to adjust the brightness on the switch.
What happens when you use LED lights?
The lights are basically strobing. If you are using poor quality LED bulbs or flood lights, then you will observe the brightness goes up and down rapidly. If the flicker frequency is below 80 to 100 Hz, then it can be observed by naked eyes.
