How to Fix Samsung TV White Spots 

Samsung TV White Spots Issue:

Thankfully, the problem is usually fixable. If you are one of those users facing the issue on your Samsung TV, you are in the right place. In this article, we will look at how you can fix this issue and enjoy content on your Samsung TV without disruption. Be sure to try these solutions before you think of buying a new TV.

Software Fixes

While most of the time, the white spots appear due to a hardware issue; there can be instances where the issue is related to the software. However, if you are sure this is a hardware issue, you can skip this section and move to the hardware fixes section. If you are unsure, try the following solutions one by one.

Fix 1: Power Cycle Your TV

A problem with the TV’s flash memory could be the root cause of the white spots. Clearing transient software faults or memory issues by performing a power cycle on your TV can help solve the issue. Performing a power cycle involves turning off the TV entirely and starting it up again, which can sometimes fix minor problems. Follow these steps to perform a power cycle on your TV:

  1. Look for the power button on the TV or the remote.
  2. For around 10 to 15 seconds, press and hold the power button. Hold it down until the screen darkens and the TV shuts off. This guarantees a full cycle of the electric power.
  3. Unplug the TV’s external components like a cable box, game console, or streaming device.
  4. After turning off the TV, remove the plug from the wall. Let it sit disconnected for at least a minute to ensure that all the power has completely dissipated.
  5. Plug in your TV and press the power button. The TV will need some time to power up and display the image.

Examine the display for any white spots. If the white spots on your TV persist after power cycling, you should try the following solutions.

Fix 2: Check the HDMI Cable

Signal noise from an improperly positioned HDMI cable could cause white spots on your TV screen. Here are some things you can do to fix the situation:

Inspect both ends of the HDMI cable that links your TV to the video source (such as a cable box, game console, or Blu-ray player) and clean the contacts if necessary.

Check the contacts for obvious signs of damage or dirt. If you see any dirt or dust on the contacts, clean them carefully with a soft cloth or cotton swab dampened with rubbing alcohol. Make sure the cable’s contacts are dry before rejoining it.

If the problem persists after cleaning the contacts, consider switching to a different HDMI input on the TV. Whether the TV has more than one HDMI input, try switching to another port to see whether the problem goes away. If the issue persists when using a different HDMI port, this will help narrow down the possible causes.

If your TV still has white spots, try disconnecting any devices that you have connected to it via HDMI. Check if the white spots still exist after temporarily disconnecting your TV from all external devices (such as game consoles, streaming devices, and soundbars). If they vanish, try reconnecting each gadget individually to find the culprit.

Because HDMI cables can degrade or develop flaws, it’s a good idea to test with a different one. Use a different HDMI cable to link your TV and video source to rule out the possibility of a broken cable. In this way, we can see if the white spots are the result of signal noise or if the cable is at fault.

If your HDMI cable seems to be fine, then you need to do further troubleshooting. Move down to the next step.

Fix 3: Update Your TV’s Firmware

Outdated firmware can also cause white spots on your TV. Although the exact reason is unknown, updating the firmware often fixes such issues. To upgrade the firmware on your Samsung TV, follow these steps:

For newer Samsung TV models, firmware updates are automatic. Make sure your TV has an active internet connection.

  1. Use the remote’s “Menu” button to access the main menu.
  2. Click “Settings” and then “Support.”
  3. Under “Software Update,” select “Update Now.”
  4. Your TV will automatically check for and download any available updates.
  5. Once the update is finished, your TV will automatically restart.

Perform a Firmware Update Manually:

  1. If you don’t have the automatic updates option, you can follow the steps below.
  2. On your computer or mobile device, go to the Samsung Support website.
  3. To access the help page tailored to your TV, enter the model number into the search bar.
  4. Seek out the “Downloads” or “Firmware” area of the help page.
  5. Get a USB flash drive and download the latest TV model-specific firmware file. When setting up your TV, be sure to use the appropriate firmware.
  6. Put the USB drive into the TV’s USB slot.
  7. Use the “Menu” button on your TV’s remote to access the menu.
  8. Click “Settings” and then “Support.”
  9. Under “Software Update,” select “Update Now.”
  10. The options “By USB” and “By External Device” will appear. Select “By USB.”
  11. Once your TV recognises the firmware update file on the USB flash drive, the upgrade will begin automatically.
  12. Don’t touch anything while the update is happening, not even the power cord or the USB drive.
  13. Once the update is finished, your TV will automatically restart.

Fix 4: Change Your Picture Settings to Remove White Spots

Changing the picture settings on your Samsung TV may help eliminate the white spots you’re seeing. Keep in mind that if the white spots are the result of hardware faults, no amount of fiddling with the visual settings will make them go. Follow these steps to change your picture settings:

  1. Use the remote’s “Menu” button to access the main menu.
  2. Click the “Picture” or “Settings” option. Depending on the TV model you have, this could be different.
  3. Click on “Picture Mode” or “Picture Settings.” 
  4. You might try switching the photo mode to see if that helps to lessen the white areas. It’s possible that using a preset like “Standard,” “Movie,” or “Cinema” will yield superior results.
  5. To further tweak the picture settings, navigate to the “Expert Settings” or “Advanced Settings” option, if one is there.
  6. Modify the settings for things like illumination, sharpness, colour saturation, and contrast. Turning off local dimming or dynamic contrast can help mitigate the white spots.
  7. Once you’ve made any necessary adjustments to the picture settings, you can exit the menu to check if they’ve resolved the white spot problem.

If the issue still persists or if you want a more reliable solution, move down to the next fix.

Fix 5: Samsung TV Factory Reset

If none of the above solutions worked, you could try resetting your Samsung TV to factory settings. A factory reset will return the TV to its original settings, wiping any user preferences and other data. Only use this option as a last resort. Follow these steps to factory reset your Samsung TV:

Note: Resetting to factory settings will delete all user data, including Wi-Fi networks, apps, and preferences. After a factory reset, you’ll need to reinstall any apps you use regularly and remember your customized settings.

  1. Use the remote’s “Menu” button to access the main menu.
  2. Click “Settings” and then “General & Privacy” from the menu of settings options.
  3. Now, click on “Reset” or “Factory Reset.”
  4. Enter the password or PIN you set up for your TV if prompted to do so. The default PIN is usually “0000” or “1234,” so try those if you haven’t set up a PIN or password.
  5. A warning will flash on the screen. Select “Reset” again to confirm. Your TV will now be reset.
  6. The reset procedure could take a few minutes. Do not unplug the TV throughout this procedure.

After completing the factory reset, your TV will restart and bring up the setup wizard. Set your TV up like it’s new by following the on-screen prompts.

Hardware Fixes

If all the software fixes don’t resolve the issue, it is time to look for hardware defects. Usually, the white spots on your Samsung TV appear because the LED diffuser lenses have been dislodged.

However, that’s not the only reason. White spots can also appear due to faulty pixels on your display. This is typically due to a faulty motherboard that you need to replace. However, if the LED diffuser lenses have been dislodged, you can reattach them, and the issue should be fixed. Follow the solutions below:

Fix 1: Reattach LED Diffuser Lenses

The backlight of your LED TV may have fallen LED diffuser lenses that generate white spots and inconsistent brightness. These are also called reflectors. The reflectors spread the light from the LEDs uniformly across the display. A screen may develop white spots or patches if a reflector comes loose or falls off. Follow these detailed instructions to resolve the issue:

IMPORTANT: If you are uneasy about attempting this repair on your own, please get in touch with a professional TV repair service, preferably Samsung support. Also, doing this yourself may void the warranty.

Step 1: Open Up your TV

  1. First, disconnect the TV from its power source by turning it off. This is crucial for your protection and the TV’s during the repair process.
  2. Then, use a clean, soft fabric or blanket on a level surface to protect the TV from potential damage.
  3. Remove the TV’s rear cover carefully. The TV model you have will determine how to remove the rear cover. If you need help with a specific model of the TV, check the manual or go online to find a tutorial.

Step 2: Reattach the LED Diffusers/Reflectors

  1. After removing the rear panel, you should be able to see the LED backlight assembly. It is a long, thin panel that sits behind the screen.
  2. Now, check for fallen reflectors in the backlight assembly. These reflectors are little, plastic or metal, and usually in the shape of a circle or square. In the place between individual LEDs, they facilitate uniform illumination.
  3. Remove any reflectors from the television that may have fallen off. Remember their original placement for easy reaffixing.
  4. Use a soft, lint-free cloth to clean the area where the reflectors will be reattached. This will strengthen the link between them.
  5. Put a dab of clear epoxy adhesive on the back of each reflector. We advise using clear epoxy since it forms a solid bond and cures clear, with no discernible effect on the screen.
  6. Now, press each reflector back into its rightful location.
  7. Wait the recommended amount of time for the epoxy to dry. Typically, this will take a few hours.
  8. Once the epoxy has dried, reinstall the TV’s rear cover by following the instructions from the manual. With the reflectors in place, the screen’s illumination should be uniform across its surface.
  9. If you still see white spots or patches on your TV, try plugging it in and turning it on.

Fix 2: Replacing LED Strips (optional)

It may be required to replace the LED strips in your LED TV if you are experiencing problems with the backlight, such as uneven brightness, dark regions, or coloured lines. You should only try this if you have familiarity with electronics and are careful with little parts, as this is a more complex repair option. If you are unsure, seek help from a professional or send your TV in for repair.

Different models of TVs use different-sized and shaped LED strips. Panels with LED lights are typically long and thin. It’s important to get the right LED strips for your TV model. You can use your manual or a simple Google search to find the LED strips for your specific TV model.

Step 1: Open Up your TV

  1. First, disconnect the TV from its power source by turning it off. This is crucial for both your protection and the TV’s during the repair process.
  2. Then, use a clean, soft fabric or blanket on a level surface to protect the TV from potential damage.
  3. Remove the TV’s rear cover carefully. The TV model you have will determine how to remove the rear cover. If you need help with a specific model of the TV, check the manual or go online to find a tutorial.

Step 2: Replace the LED Strips

  1. Disconnect the old LED strips from the TV’s circuit board by carefully removing any connectors or ribbon wires connecting them to the board.
  2. When replacing the strips, it is important to remember their current position and orientation.
  3. Remove the old LED strips carefully by peeling them away from their adhesive or mounting brackets.
  4. To replace old LED strips with new ones, simply attach the new ones where the old ones were.
  5. Align them properly and use the adhesive or brackets provided to keep them in place.
  6. When reconnecting any ribbon cables or connectors, be sure to do so securely.
  7. Before reassembling the TV, make sure the new LED strips work by plugging it in and turning it on.
  8. Check that the backlight is bright enough and that the colours are consistent throughout.
  9. If everything appears to be in working order, turn off the TV and replace the back.
