Why Won’t My LED Lights Turn On?

Share this Article

If you’ve been using LED lights or LED strip lights for a while, you’ve probably encountered various problems that require troubleshooting. Sometimes your LED lights may not turn on, sometimes your LED lights suddenly stop working, and sometimes your LED lights may not work after cutting them! But here you are because your LED lights are not turning on! And we will discuss about the recent problem and the solution of your lights!

If your brand LED lights did not turn on, the problem is most likely a faulty or poor pin connection. This is similar to charging your phone or plugging something into a power source. You will not get the desired result if the metal prongs are not securely connected inside the source. LED strip lights also follow the same principle.

Most LED strip lights employ a series of small connectors (pins) to conduct electricity throughout the light strip. Bad pins are uncommon for LED strip lights, so it is more likely that the pins are not correctly plugged in.

You should also make sure that your power source is connected correctly. If none of these solutions work, it could be a problem with the wiring, in which case your LED light strip will need to be repaired or replaced. But before replacing, you should have checked out why won’t your lED lights turn on? Here we have listed seven possible causes of your problematic lights!

Why Won’t My LED Lights Turn On?

When you turn on an LED light, it does not always turn on. They may flicker or even blink! What could be the possible cause? There are a few possible causes for your LED lights not to turn on. Read the seven most common reasons why your ights won’t turn on.

  1. You are using a low-quality lights
  2. Your lights have a bad pin connection
  3. Your lights capacitor may be bad or faulty
  4. Your LED light’s power source may be incorrect
  5. Your LED bulbs may be screwed in too tight
  6. You may have grid problems
  7. Your lights wire may be damaged or loose

Low Quality LED lights

You may notice that a low-quality LED strip does not perform as well as a higher-quality strip. In the worst-case scenario, it may not turn on at all.

When the power supply is connected to some low-end strips, they will flicker or even dim slightly. It is not an issue with all of them, but some simply do not do what they are supposed to, causing your hard-earned money to be wasted.

You may be wondering what distinguishes a high-quality strip from one that performs poorly. Much of it is due to the way they are wired.

Bad Pin Connection

LED lights will not turn on if they have a faulty pin connection. This can be solved easily by replacing the pin connection with a new one. To determine if this is the cause of the problem, disconnect the pin and examine it. Sometimes, these will be bent or not fully connected, but even if they are not, it is always a good idea to check and rule out this possibility.

Bad Capacitors

If your capacitors are bad, your LED lights might not work. These are small pieces of circuitry that help the light work right. If they break, this could be why your lights aren’t working right now.

You don’t have to buy new LED lights before replacing the capacitors of your lights. When you buy a set, you may get more than one type of capacitor, so one of them will likely work perfectly with your lights.

Incorrect Power Source

Powering an LED light or a group of LEDs is not the same as powering most electronics. LEDs, unlike most electronics, require a constant current source rather than a constant voltage source.

For that, LED lights may not turn on or be fused if you don’t use the right or bad power source. Make sure you are using the correct power source for your LED lights, as each type of LED bulb needs a different voltage to work right.

LED Bulbs Screwed in Too Tight

It is essential to ensure good contact between the fixture and the light bulb, but overtightening will ruin the fixture-to-bulb connection. Examine the small brass tab inside the light socket to see if this is the case. The tab acts as a spring and should protrude at about a 30-degree angle.

If the tab is thoroughly pressed into the socket’s base, you’ll need to replace the fixture or possibly bend the tab back up. To repair the tab, turn off the power at the breaker and bend it upward with needle-nose pliers. Do not insert your finger or any other object into the socket without first turning off the breaker that supplies power.

Grid Problems

LED not turning on due to grid problems can occur for various reasons. If the power supply is connected to a surge protector or an extension cord, it is possible that too much electricity was flowing through the grid, causing you to lose one of your LEDs.

Even though LEDs do not require much power to operate, when combined with other devices on the grid, it is possible that your grid will be overwhelmed and will not provide adequate power to the LED lights.

If this occurs, you should take a step back and examine what is on the grid.

Damaged Or Loose LED lights Wire

Another common reason is the wires of your LED lights are damaged or loose. There’s a chance your lights were cut during manufacturing, so you’ll have to return them and get new LED strips.

Animals can also damage wires, mainly if the lights are used outside. There are also instances where the wiring has been shorted, which occurs when two positive wires or a negative wire touches another negative wire.

How to Fix LED Lights that won’t Turn On?

Maybe you have already guessed about your LED lights problem with the solution. But here we are going to tell you what to do when your LED lights won’t turn on!

  1. Try to buy high-quality branded LED lights
  2. Make sure that the voltage and current of your power supply are compatible with your LED strip
  3. Look at and turn off any other devices on the same circuit
  4. Look for loose connections that you can see
  5. Look for obvious signs of a short circuit
  6. Look for signs of short circuits that can’t be seen
  7. Make sure your LED lights are not screwed too tightly
  8. Make sure your LED lights pin and capacitors are working fine

What are the Most Common Problem’s of LED Lights?

LED lighting is becoming increasingly popular due to its energy efficiency and long lifespan. LED lights, like any other type of technology, can, however, technical faults from time to time. The top five most common LED light problems are listed below.

Dimmer Problems

Many homeowners are switching to LED lighting, drawn by the promise of energy savings and longer bulb life. HOWEVER, some LED lights may not work with certain types of dimmer switches, resulting in dimmable LED flash and flicker.

One of the most annoying aspects of LED lights is when they begin to flicker or dim unexpectedly. This can happen for various reasons, and determining the cause can be difficult. But most of the time, it is caused by a loose connection or a voltage drop!

Color Changing Problem

The intensity of light’s three primary colors, red, green, and blue, can be “tuned” to produce different colors (RGB). This is why televisions and computer screens can display various colors.

However, because RGB LED lights are manufactured on such a small scale, they can be challenging to tune. There could be several reasons your LED RGB color-changing light bulb is flickering or not displaying colors correctly.

Poor Qality Color Rendering

While LED lighting has many advantages over traditional light sources, it can occasionally have poor color rendering quality. As a result, the colors of objects illuminated by LED lights may appear inaccurate. However, there are ways to improve the color rendering quality of LED lighting.

You can solve this problem by purchasing a high CRI product. The Color Rendering Index, or CRI, measures how well a light source renders colors. A higher CRI indicates improved color rendering. LED lights with a CRI of 80 or higher are preferable.

Too Cold Color

One of the most common issues with LED lighting is that it can appear too cold and harsh. When the color of light is very white and cold, it contains a high proportion of blue light, though it is not visible as blue. This blue light has been shown to disrupt the body’s natural sleep cycle, resulting in fatigue and headaches.

This effect can be mitigated by using warmer-colored LEDs or diffusing the light with covers or filters. Taking these precautions makes it possible to reap the energy-saving benefits of LED lighting without sacrificing light quality.

Flickering LED Lights

Many people are familiar with fluorescent light flickering, but did you know that LED lights can also flicker, which can be annoying and even cause headaches in some people? While it may appear to be an annoyance, some scientific explanations exist for this phenomenon.

To begin, it is critical to understand that LEDs emit light differently than other light sources. Instead of using an electrical current to generate light, they use semiconductor chips that create light as electrons pass through them. This is referred to as electroluminescence.

Now, let’s get back to the flickering. The electrical current passing through the semiconductor chips is not always smooth and consistent, which is one reason why LED lights may flicker. If there are any fluctuations in the current, the LEDs may flicker.

Final Words

As you can see, there are many reasons why LED lights and LED light strips can stop working. Sometimes, the problem could be caused by something outside the house, like a power source or dimmer that doesn’t work right.

In other cases, the problem could be how your strip is connected. This could make it harder for power to get to your LED light strip or change the colors of the light it gives off. In less common cases, it could be a problem inside the LED light strip that must be fixed by replacing the whole thing.

LED light strips are made to last, especially if you buy them from a good company. This means that most problems can be fixed by the person having them. We hope you found this guide to resolving issues with LED strip lights helpful and informative.
