13 Easy Steps To Fix Bright Spot On Samsung TV Screen (2023)

How To Fix Bright Spot On Samsung TV Screen

A bright spot also consistently appeared on my Samsung TV before. 

But of course, as a tech expert, I knew exactly what was wrong. 

So I went out and bought some glue.


Because that was all I needed to fix this issue.

Continue reading to discover:

  • 13 detailed steps to solve this problem. 
  • Why this bright spot appears on your Samsung device.
  • How to correctly glue the reflectors on your TV, so you don’t damage them. 
  • And this is just the beginning… 

Why is there a bright spot on my Samsung TV screen?

There’s a bright spot on your Samsung TV screen because a reflector is loose inside the TV. Those reflectors are supposed to distribute light throughout the TV display. So if they come off, the LED shines on 1 area only, causing a bright spot to appear on the screen. 

How to fix bright spot on Samsung TV – 13 steps

Before you proceed with the exact steps for this process… 

Bear in mind that this solution requires you to open your TV up. 

Important: I recommend only proceeding if you have experience handling TV components. Or those of similar devices. Because while this is an easy fix, you still need basic technological skills for this process. 

However, if you’re inexperienced yet still eager to try this out yourself…

Just ensure that you follow the necessary safety measures when handling electronic appliances. Specifically, make sure that you’re:

  • Wearing footwear (any type). 
  • Following the detailed instructions.  
  • Using safety gloves throughout the whole process.

So that both you and the TV will be safe while doing this fix. 

And now that’s noted, proceed with the 1st step, which is to…

#1: Prepare the necessary items

The bright spot on your screen is caused by the loose reflectors (aka lens) inside your Samsung device. 

That said, you need to open up your TV. And glue these lenses back to their original positions to fix the problem. 

But to do this…

Prepare these items first:

And once you have all of these, proceed to…

#2: Unplug your TV from its power source

Turn your TV off and unplug it from the wall outlet.

Note:  Wait for at least 15 minutes. So that your TV’s capacitors can drain all of their residual power. And you won’t risk getting shocked by electricity when you open it up later. 

#3: Put your TV face down on a flat, soft surface

Place a thick comforter or bedsheet on a table large enough for your TV screen to lie on. 

Then, gently lay your TV face down on that table. 

“Why do I have to put a comforter?”

That’s because the soft surface will ensure you won’t damage your TV screen. So it’s a crucial part of this process.

Now, if you’re thinking…

“I don’t have a table large enough to hold my TV.”

Then you can simply place your Samsung device on your bed because it’s also a soft surface. 

#4: Remove the screws from the back of your TV

Thoroughly scan through the back of your Samsung TV.

And remove all the screws in it with the help of your screwdriver. 

Now, I recommended getting a screwdriver magnetizer and demagnetizer earlier.

And this is when it comes in handy.

See, when you hover your screwdriver between the Magnetize section of this tool…

The screws that come in contact with the screwdriver afterward will automatically stick.

And before you get confused about what I’m talking about…

Here’s a short video that shows this screwdriver magnetizer tool in action: 

That said, simply put your screwdriver between the Magnetize section every minute. Or when it loses its charge. 

And this way, all the screws you remove will stick to your screwdriver. So you won’t have difficulty lifting the screws from your TV. 

Important: The screws on your TV will differ in size. So remember where you remove each of them from. And this way, you can return them with ease later. 

#5: Remove the back cover of your TV

After removing all the screws from the back of your Samsung device, gently remove its cover.

Now, if you’re finding it hard to lift it up…

Use the small prying tool you prepared earlier to raise the edges of the TV. And use your fingers to widen the gap between the body and its cover. 

#6: Flip your TV 

Now that you’ve removed the cover of your TV… 

Place it on its back so that its screen is facing your ceiling. 

“Won’t this destroy the exposed components on the back of my device?”

Don’t worry. It won’t. That’s because Samsung TVs have thin and light bodies. 

Fun fact: Their lightweight design is actually 1 of the reasons why Samsung TVs are so expensive.

#7: Remove your TV’s screen

Remove all the screws surrounding the edges of your TV, if there are any. 

And use your prying tool once more to lift the edges of your Samsung TV frame. 

After that… 

Disconnect the ribbon cables connected to the screen using your fingers. Then carefully remove it from the body of your TV. 

Note: Place the screen on a clean, flat surface. If you don’t have an area like this, I recommend laying a thin layer of paper on a table or a floor. And place your TV screen on it.

#8: Lift the diffuser panel from your TV

The white surface you’ll see is the diffuser panel of your TV.

And it’s the 1 responsible for diffusing the lights from the reflectors of your device. 

That said, you also need to remove this component from your TV.

But before you do so…

  1. Unsnap the bezels connected to the diffuser.
  2. Get a pen and 3 pieces of paper. 
  3. Label the papers (top, right, and left). 
  4. Lightly stick the papers to the respective sides of the reflector. 

Note: Use weaker tapes (like masking tape) for this.

“Why do I have to label the sides?”

That’s because placing the diffuser in the wrong spot will give your TV a weird-looking display. 

#9: Reglue the reflectors of your Samsung TV

Below the diffuser panel…

You’ll see small, transparent lenses evenly distributed on your TV. 

And if you’re not familiar with them, these are the reflectors of your device. 

As you can see, some of these lenses have come loose. 

So you have to glue them back into their place.

However, before you do so…

Pro tip: Slightly snug all reflectors on your TV. That’s because others appear to be in place but are actually loose. So if you don’t check each of them now, another lens might fall off again soon. 

Now, collect all the loose reflectors. And proceed with the… 

Steps to reglue the lenses of your TV:

Step 1: Observe your TV’s LED lights and reflectors

Surrounding each LED light of your TV…

There are 3 post-holes or small circles meant to guide the positions of the reflectors.

That said, on each reflector lens… 

3 posts should sit on top of the holes surrounding the LED. 

So when putting the reflectors on top of the lights…

Ensure that the posts in the lenses sit perfectly on top of the holes around the LED. So that they’ll be secure and won’t come off easily. 

Step 2: Put super glue on a piece of paper

This will make it much easier to access the glue later. 

However, don’t overdo this step. Because you’ll only need tiny drops of the superglue. 

Plus, you can always add more of it later if it isn’t enough. 

Step 3: Put a bit of glue on each post-holes surrounding your LED light

Dip the tip of a toothpick into the superglue sitting on the paper. 

And lightly poke it inside 1 of the post-holes you observed earlier.

After that, do the same for the remaining 2 holes around the LED light you’re working on.

And proceed to… 

Step 4: Place your reflector on top of the glued post-holes 

Ensure that the posts on the lenses sit on top of the holes. 

And slightly twist the reflector left and right to ensure it fits perfectly.

Note: The lens shouldn’t move when you nudge it. So if it does, its posts aren’t aligned to the holes yet, so you should realign it. 

Step 5: Repeat steps 4-5 for each LED light with a loose reflector

Remember not to overdo the glue. And simply use the tip of the toothpick to apply it.

That’s because using too much glue can cause it to leak to the LED light itself.

And this can either destroy the LED or lower its brightness. 

After you’ve returned all the reflectors to their respective spots…

#10: Put the diffuser panel back in its place

You’ve labeled your diffuser earlier.

So this step will be easy.

That said, simply follow the guidelines you’ve written.

And insert the tabs (thin holes) surrounding your diffuser to the hooks around your TV. 

After doing so, press the edges of your diffuser down. So that it can lock into place. 

Then remove the labels you’ve placed on your panel before proceeding to… 

#11: Return the screen of your TV

Align the screen perfectly on your TV. 

Because if it’s not, it’ll crack when you try to snap it into place later. 

Along with the screen, return the frame of your TV as well. 

And ensure that both lock into their positions by pressing down their sides.

#12: Return the back cover of your TV

Return The Back Cover Of Your TV

Put your TV face-down once more.

And screw its back cover into place. 

Once again, if you have the magnetizer and demagnetizer tool…

Hover your screwdriver on the magnetizer area once in a while so the screws will stick to it. 

This way, you won’t have difficulty aligning the screws to the TV.

#13: Test your TV display

Return your TV to its stand or mount. And plug it into its power source.

After doing so, turn it ON and play a couple of shows or movies. 

And you’ll notice that your TV’s bright spots are now gone. 

That said, you can continue streaming on your Samsung TV without disruptions.
