(Quick Fix) Bright Spots on Samsung TV – 2023 Guide
I bought my Samsung smart tv back in 2020, but a few days ago, it started showing bright spots on the screen.
Initially, I started worrying, but later, I figured out the problem and fixed it.
If you’re facing the same issue, troubleshooting is straightforward, and you can fix the issue now.
So why are there bright spots on Samsung TV?
Bright spots occur on the TV screen because of the loose LED reflector or diffuser inside the TV screen.
Reflectors spread the light on the TV screen; if they are loose, LED light shines on specific parts, making them look like bright spots.
The problem has easy solutions that I’ll discuss further in this article. I’ll also cover different reasons and solutions behind bright spots on smart TVs.
Read till the end and learn about your problem and fix it right now.
Why Are There Bright Spots on Samsung TV? Three Reasons
Here are the main reasons that cause bright dots on your Samsung TV screen.
1. Loose LED Reflector Connection
The LED reflector is a small component that reflects light from the LED to the diffuser.
A loose reflector connection can cause bright spots on your Samsung TV screen.
You may notice that the bright spots appear in a specific screen area, mostly in the corners.
If that’s the case, there’s a high probability of a loose LED reflector connection.
2. Weak or Disconnected LED Diffuser
The LED diffuser helps to scatter the light from the LED evenly across the screen. When it’s weak or disconnected, it can cause a bright patch on your TV screen.
You can determine if the LED diffuser is causing the issue by taking a flashlight and shining it directly on the bright spot.
You have a weak or disconnected LED diffuser if the bright spot disappears.
3. Defective or Dead Pixel
Dead pixels are small black dots appearing on the screen, while bright pixels are white dots appearing repeatedly in the same location.
A defect in the pixel causes them and can cause bright spots. Dead or defective pixels are more prominent when the screen has a dark background.
How to Fix Bright Spots on Samsung TV? 4 Solutions
Bright spots are usually caused by dislodged lenses or fallen reflectors in the LED backlight.
Here are four solutions to fix it.
- Reattach Dislodged LED Diffuser Lenses
- Fix the Fallen Reflectors in Your Backlight
- Use Glue to Fix the Loose Reflectors
- Samsung TV Factory Reset
1. Reattach Dislodged LED Diffuser Lenses
- Turn off the TV: Before starting any repairs, turn off and unplug the tv for safety.
- Prepare the Workspace: Choose a clean and well-lit area to work on your TV. Place a soft cloth or towel on a flat surface to protect the screen.
- Remove the Back Cover: Carefully use a screwdriver to remove the screws securing the back cover. Keep track of the screws and set them aside safely. Lift off the back cover gently and set it aside. If your Samsung TV is Screwless, be careful to open the Back cover. Watch this Video Below to learn how to open screwless tv.
- Locate the LED Light Panel: After removing the back cover, you’ll find the LED light panel in the center of the TV. It’s a long rectangular board with multiple LED lights.
- Identify Detached LED Diffuser Lenses: Look for white spots on the LED light panel, indicating detached LED diffuser lenses. These lenses are small plastic pieces that distribute light evenly.
- Reattach the LED Diffuser Lenses: Carefully examine the lenses to see how they fit onto the LED lights. Each lens has small clips or tabs aligning with corresponding LED slots. Gently push the lenses back into place, ensuring a secure fit.
- Check for Proper Alignment: Verify their alignment once all the LED diffuser lenses are reattached. Ensure they are correctly positioned without any gaps or misalignment.
- Place the Back Cover: Carefully position the back cover onto the TV and secure it with the screws. Tighten the screws appropriately, avoiding over-tightening to prevent damage.
- Power ON the TV: Plug in the TV and turn it on. Check the screen for any remaining white spots. Properly reattached LED diffuser lenses should eliminate the white spots.
2. Fix the Fallen Reflectors in Your Backlight
If the bright spots on the screen are due to fallen reflectors in the LED backlight, you can fix them by unscrewing the back cover of your TV.
Now look for the loose reflectors, and position them back in place.
Use a small amount of adhesive, such as tape or glue, to secure them before you screw the cover back on.
3. Use Glue to Fix the Loose Reflectors
If the reflectors are not entirely dislodged but have a noticeable gap between them and the LED backlight panel, you may apply a small amount of white glue.
Make sure that it does not run onto other parts of the TV. Allow it to dry for at least a few hours, then turn on your TV to see if the bright spots are gone.
4. Samsung TV Factory Reset
If the above solutions do not work, the last resort is factory resetting your Samsung TV.
This action will restore your TV to its default settings, which can solve software-related issues.
To factory reset a Samsung TV, you can follow these steps:
- Make sure the TV is turned off.

- Press the power button on your TV to turn it on.
