Do Magnets Affect LED TVs?

Do Magnets Affect LED TVs? – [You Should Know Everything!]

Throughout our childhoods, we have been warned by our parents that we can’t take magnets closer to the TV. Right?

But times have changed, those were CRT (Cathode Ray Tube) TVs, and this is the era of LED TVs. So, the question is: Do Magnets Affect LED TVs?

No! Not Much! There is a slight effect of a magnet on LED TVs, but it’s not as big as old CRT TVs.

Brief Introduction to Magnets and Their Working:

A magnet is a material that attracts other metals. Right?

But here, you should know one important thing about magnets. The magnet generates an electric field around itself and the metal it attracts.


Due to this electric field and magnetic ability, two metals get attracted toward each other. The general working of magnets shows why it affects TVs (especially old CRT TVs).

It’s because TVs are mainly made of different kinds of metals, and the magnet will attract them.

Why Do Magnets Affect Old TVs but Not Modern Ones?

Before knowing the difference between old and new TVs, you must know how magnets affect TV (in general).

You already know that TV is filled with metals. So, when you place or put a magnet closer to a TV, it creates an electric field and eventually attracts those metals (mainly their small particles).

Now that you have a general idea of the whole thing let’s understand why magnets affect old TVs but not modern ones.

CRT and LED TVs are extremely different from each other when you open them and understand their working. In CRT TV, everything is done in a cathode ray tube which is a tube filled with charges.

Now, this large tube uses a beam of electrons to create the image on the screen. This beam emits electrons that glow and create images on the screen.

When the magnet is placed close to the screen, those electrons start moving toward the magnet instead of their initial target. That’s how

On the other hand, LED (Light Emitting Diode) TVs emit light that we see on TV screens without the use of any charges or an electron gun.

Moreover, Modern TVs have magnetic shielding to protect them from magnetic force. These shields are made of materials like mu-metal, which are highly effective at blocking magnetic fields.

Why Magnet Can Still Affect LED TVs?

Even after so much shielding and protection, LED TV can (rarely) get affected by magnets. But how and why?

The biggest reason why a magnet can still affect LED TVs is that although it doesn’t have an electron beam gun, it still uses the magnetic field to create the image on the screen.

Why Magnet Can Still Affect TV

If any external magnetic field does its job and is strong enough, it can interfere with the magnetic field inside the TV and cause damage.

Here, the shield of mu-metal plays a big role, but if it’s your bad day or your TV is made with bad shielding material, you can still face issues.

Symptoms of Magnet Interference on LED TVs:

With old CRT TVs, it was quite easy to notice when magnets interfered with the TV. But now, as it is super rare to have your TV getting affected by a magnet, most people don’t know how to know whether a magnet has affected LED TV or not. So, we are here for you:

Color distortion:

Yes! It’s the same color distortion that we have already faced with old CRT TVs in which pink and blue colors distort on the screen.

Screen distortion:

Screen distortion is also a thing. In this symptom, the TV’s image will either be curved or tilted.

Flickering or flashing:

If your TV is flickering, flashing, and making it difficult to view the content, the magnet might have done its job.

Dead pixels:

If the magnetic field of that magnet is stronger than the inner magnet field of the TV, some of the pixels can stop working, resulting in black spots on the screen.

Reduced picture quality:

It’s probably the rarest symptom. Magnets can cause a loss of detail and sharpness on the TV screen.

Types of Magnets that Can Affect LED TVs:

When a magnet gets even super close to an LED TV screen, it has many things to deal with before interfering with the TV or its image.

Magnets that Can Affect LED TV

But still, there are some types of magnets that can somehow affect LED TVs:

Permanent magnets:

These are the types of magnets that were always in or with TV (maybe in speakers of TV). They can affect LED TV if they start working improperly or are placed too close to magnets in the TV.


These magnets are created by an electrical current and are commonly used in solenoids, transformers, and other electronic devices.

Strong Magnetic fields from other devices:

Almost every electronic appliance, including refrigerators, and microwaves in your home, has a magnetic field 24/7. So, if you think any of your home appliances can have a stronger magnetic field than LED TVs, don’t place it any closer to the TV.

Magnetic jewelry:

Magnetic bracelets, necklaces, and other types of jewelry can potentially affect an LED TV if they are brought too close.

What to Do If Your LED TV is Affected by Magnets?

The only solution that is easy and can be done by you is demagnetizing to get rid of this issue.

But should you do it with your LED TV?

Is it risk-free?

Yes, you can do it, and you should do it right now. There will be no risk if you do it the right way. So, follow these instructions:

  1. Turn on the TV.
  2. Bring a coil or magnet near the TV aim it directly in front of the TV, and slowly wave it in a circular motion.
  3. This will cause more damage for a bit, so don’t panic about it. And keep repeating the process until it starts working.
  4. Set the coil or magnet aside and restart the TV again.


In the end, you know more than what you wanted but exactly what you needed. It’s impossible that you still don’t know whether magnets affect LED TV or not.

Other than that, you now also know how to identify whether your TV is affected by a magnet and then solve the issue by demagnetizing it.
