As an exasperated owner of a Samsung TV, I found myself frustrated when I noticed a few white spots appearing on my screen. Not having prior experience with this issue, I decided to do a bit of research and testing to figure out what was causing the spots and how I could fix them. In this blog post, I’m here to share how I ultimately solved the problem, as well as other solutions that I discovered along the way.

Why are there white spots on my Samsung TV
There are three possibilities when it comes to diagnosing the cause of the white spots on your TV. The first cause is a fallen reflector inside the TV. A reflector is a lens inside the TV panel that sits in front of the LED backlight and amplifies the light on the screen.
The second cause of white spots on a TV screen is a damaged processor, which may occur because of an overheating issue. An electrical surge can damage the processor, and a lack of cooling around the television can cause the problem, too.
The third reason white spots may occur on your TV is a dead pixel or series of dead pixels. Sometimes pixels get stuck in a particular state and no longer respond to commands sent to them by the television’s processor.
Sometimes, modifying the settings on the television can fix the issue. In other cases, a professional’s help might be the only way to eliminate the white dots.
Try doing a soft reset
Often, a soft reset is all that is needed to solve issues on a Samsung TV. A soft reset does not erase any data. To soft reset a Samsung TV, you simply need to turn the TV off, then remove the plug from the wall outlet and wait for 60 seconds, then put the plug back in and turn the TV on again.
Try a software update
There is a small possibility that there is a software bug causing the issue. You can turn on automatic software updates by going ”settings” then ”support” then “software update” and ensure ”Auto Update” is turned on. Alternatively, you can manually update over the internet by clicking ”Update now”.
Dealing with a Fallen Reflector on a Samsung TV
A fallen reflector on a Samsung television is a job best handled by a professional because fixing the tv on your own may void the warranty. To fix a fallen reflector on a Samsung TV, the work involves taking the television apart and readjusting the fallen reflector.
The process requires disassembling the entire rear of the television, disconnecting the speakers, taking the circuit board out of its place, and readjusting the reflector to secure it with glue. If you’re absolutely determined to take apart your television on your own, this is the step-by-step process you can use to repair your fallen reflector.
1. Ensure the television is off and not connected to any power supply.
2. On the back of the TV, remove the screws that hold the back panel on the television.
3. Remove the metal tabs on the television.
4. Take the speakers off the television by disconnecting them.
5. Remove the circuit board from the metal plate and lift up the metal plate.
6. Lift the tabs on the plastic frame and search for the fallen reflector.
7. Once locating the fallen reflector, glue it back in place.
8. After the glue is dry, complete the above steps in reverse to reassemble the TV.
A television repair professional can perform this quickly, and paying them to fix the television generally costs less than buying a new tv.
Dealing with a Damaged Processor on a Samsung TV
A damaged processor that causes white dots on your Samsung TV is repairable. However, it may need replacement if the damage is too severe, and modifying the settings doesn’t help eliminate the appearance of the dots. You’ll want to have your remote and access to the television’s settings to make the white dots disappear.
Here are the settings you’ll need to change to make the white dots disappear.
1. Reduce the backlight setting as low as possible.
2. Reduce the television’s brightness to the lowest acceptable level.
3. Turn off auto-adjustments that change the brightness of the television.
4. Make all settings on the television manual, so none of the settings change.
Reducing the television’s brightness – both the backlight and the overall brightness – can reduce the appearance of the white dots on your Samsung television.
Unfortunately, if the white dots are still visible after you modify the settings, you may need to replace the entire processor, which is a complicated endeavor most often performed by an expert.
Dealing with damaged pixels on your Samsung TV
Over time, small white dots may appear on your Samsung TV that aren’t as large as those you might see because of a damaged processor or a fallen reflector. When it’s a tiny white dot that won’t disappear, the problem could be a dead or malfunctioning pixel.
While it’s impossible to fix a completely dead pixel, sometimes they can be revived after starting to malfunction.
To revive a dead pixel:
1. Take a microfiber cloth and press it gently on the area of the dead pixel.
2. Make sure the television is off before placing the fabric on the TV.
3. After pressing gently, turn on the power supply to the TV and see if the problem corrects itself.
If pressing the pixel gently doesn’t work, some television owners may swipe downward on the television with their cloth to fix the problem. Unfortunately, a pixel that doesn’t revive isn’t something that may be reasonably repaired on a television.
Try a hard reset
A hard reset involves completely reseting the TV to its factory defaults and your data will be erased.
To do this, do the following:
- Turn on the TV and press the “Home” button on the remote
- Go to “settings”
- Then click “general”
- Then click “reset”
- You must then enter a 4 digit pin number which is 0 0 0 0 by default
- Then click ”Yes” to reset the TV
- The TV will then turn off once it has finished resetting
- You can now turn the TV back on and set it up again
Always check the warranty before trying to fix a Samsung TV
Samsung televisions come with warranties just like any other large electronic device, and many problems are covered under warranty for the first few years of ownership. Samsung will send a repair person or persons out to your location and repair the television, even if it’s a significant repair.
In the event your television isn’t under warranty anymore, and you want to get the white dots on the TV repaired, you may want to call a local television repair professional. White spots on a television are common, and fixing them may be a more affordable option than completely replacing the television.
