People always want to know about Why Won’t My LED Lights Turn On? So here is the explanation. LED lighting is an excellent lighting solution for today’s world, with numerous advantages and a lifetime of up to 50000 hours. Nothing, however, is without flaws. In addition to the advantages, LEDs can occasionally experience problems when in use. If you’re curious about six frequent LED Lighting Issues, this article will explain them in detail and show you how to solve them.

Why Won’t My LED Lights Turn On?

If your LED light strips won’t light up, there’s probably a bad pin connection to blame. This is comparable to plugging anything into an outlet or charging your phone. You won’t achieve the intended outcome if the metal prongs are not tightly attached to the outlet. When using LED light strips, the same idea holds.

LED Lights Have Failed

Are your LEDs supposed to last up to 50,000 hours yet abruptly quit working after only a year, some few months, or even a few days or weeks of use? Because there are many possible explanations, this is a major issue. It won’t be easy to figure out the cause unless you’re an LED specialist or a professional electrician.

LEDs, unlike incandescent lamps, are not consumed (broken filament), but only dim (decrease brightness). They can, however, be damaged by the burning of other parts (not including the led chip) as a result of negative current and installation factors.

Heat buildup, over-tightening bulbs, and installing LEDs in the wrong electrical circuits and components are all major causes of LEDs Failing To Perform. Furthermore, low-quality capacitors, drivers, and diodes are major contributors to LED Bulb Failure.

What Are We Going To Perform Regarding LED Bulb Failure?

When an LED suddenly stops working, the first thing you should do is check the circuit breaker. If there is no issue, cut the power and inspect the lamp’s internal components, such as capacitors and drivers. 3 Causes Of LED Lights Not Working & How to Fix Them

Reason 1

If your capacitors or drivers are of poor quality, replace them yourself if possible or call an electrician to assist you. You can also repair the LED bulb if they are too tough to fix or replace.

Reason 2

Inadequate current or accessories: The easiest way to avoid this is to replace all of the bulbs with new components at the same time, packed together so that they are all compatible and create a smooth and effective system. This will help reduce the chances of excessive radiant heat and, as a result, increase light efficiency.

Reason 3

If the copper vortex is bent, you must cut off the power and bend it forward with needle-nose pliers at an angle of about 20 degrees from the bottom of the socket. After fitting the bulb, there are a few things to keep in mind to avoid similar situations: Do not screw the bulb in too tightly or too quickly; simply turn it on until the light turns on and then turn it off.

The Color Of A LED Light Doesn’t Change

Your LED lights aren’t changing color because of a faulty pin or a bad pin connection. A backward connector or reversed polarity is also a faulty pin connection. LED strip lights often feature two sides: one with a positive charge (noted by a dash) and the other with a negatively charged (usually indicated by the manufacturer’s logo).

The positive sign on your strip lights should be indicated by the pointer on your connectors. If the color of your LED strip light doesn’t change, it’s most likely due to reverse polarization. In this situation, try reconnecting the strip lights by flipping them around.

LED Lights Have Been Turned Off

There are a variety of reasons why your LED light is dimming. I’ll go over some of the most frequent causes that many people face. If the LED flashes every time you turn on another gadget while in use, the circuit is most likely overloaded. When too many devices are used at the same time, the power must be broken down to maintain balance, resulting in a feeble light.

Fire, explosion, and electric shock can all result from overloaded circuits. To resolve this issue, you must first separate a device in order to lessen the circuit load. A competent electrician can relocate you to a different circuit in the long run. LED fading can also be caused by old or faulty cables.

Over time, wire connectors might corrode, resulting in lower power and brightness. Furthermore, a damaged chord poses a significant risk to human life because it might result in fire, explosion, or electric shock, among other things.

In this instance, the only solution is to replace the entire cable before it creates a big problem. The dimming of the LEDs is due to a fault with the grid. For example, an exceptionally high need for electricity, weather-related power outages, and transformer failures. All have a significant impact on the LED’s normal operation.

The solution to this problem necessitates the assistance of electrical professionals. Another common reason for LED fading is that the bulb has reached the end of its useful life. During its lifetime, the LED bulb will not burn like a fluorescent bulb, but will merely dim. This dimming is usually only discovered at the end of a dedicated life (if the normal operation does not encounter any technical errors during use).

LEDs have an average illuminating time of around 25,000 hours, after which time their brightness will be lowered by roughly 70%. If this is the case, you should replace the replacement LED bulb before the light life expires. It is not beneficial for your eye health to use LEDs with too dim light.

What Do You Do If Your LED Lights Won’t Turn On?

  • Verify that your power source’s voltage and current ratings are appropriate for your LED strip.
  • Verify that your power supply is operating properly.
  • Inspect and separate any additional accessories on the same circuit.
  • Scan the connections for any obvious loose ones.

How Do You Fix An Unresponsive LED Light?

How to Remedy It

  1. The LED strip’s power should be unplugged.
  2. Take the remote’s battery out.
  3. Disconnect both ends of the dimming wire (LED controller).
  4. Reinstall the batteries and plug the LED controller back in.


Hopefully, you’ll find useful information in this post on Why Won’t My LED Lights Turn On? Remember that when such issues arise, you must be patient in determining the source of the problem in order to find a suitable solution.

Most importantly, always keep yourself safe by disconnecting the power source when working on the lights and only repairing when you are confident and aware of the problem. Instead, hiring an experienced electrician is the best and most secure solution for you.

Frequently Asked Questions

When your LED lights won’t switch on, what should you do?

A defective power supply could be the cause of the LEDs not lighting up at all. Simple answer: If you have multiple power supplies, try plugging in a different power source to the same strip to check if it works now. If it does, you’ve got a faulty power source and will need to replace it.

Why did my LED stop working all of a sudden?

If your Study to describe isn’t working at all, the most likely cause is poor internal wiring that hasn’t been properly linked to the driver. Fitting led Strip panels with an unsuitable dimmer switch will produce flickering, while this is not strictly a wiring fault.

Why won’t some LED lights switch on?

Another reason an LED light may fail is because of a phenomenon known as efficiency droop. Basically, as the LED lamp is turned on and the electrical current flowing through the LEDs rises, the LEDs’ luminous effectiveness drops by up to 20%.

What are the signs that my LED is blown?

It’s a light-emitting diode (LED). Connecting it to a battery and seeing if it lights up is the simplest approach to see if it is damaged. Because you can’t unscrew the white plastic unit, the connection wires, resistor, or LED itself could be harmed if the LED doesn’t glow.
