  • 5 mind-blowing reasons why your Samsung TV has a red screen. 
  • And this is just the beginning… 

Why is my Samsung TV red?

Your Samsung TV is red because it’s not receiving any signal. Its picture settings aren’t calibrated correctly. Also, your TV could be overheating. Or it has problems with the display panel. Otherwise, your Samsung TV has outdated firmware.  

Red Samsung TV: 3 things you need to know

#1: Samsung TV connections


They’re everything that ties us to the people we love.                                                                                        

Without these bonds, we’re just ships that pass in the night. 

And like us, your Samsung TV also needs connections to work. 

I’m talking about the links between your TV and any external device. That includes: 

All these external devices send signals to your TV. So that your TV can display picture and sound outputs. 

Aside from that, there are also “connections” inside your Samsung TV. And these are mainly electrical wirings. 

But, 1 to keep in mind is the connection between the mainboard and the T-con board


These boards are responsible for getting signals from the sources. And projecting them into the screen. 

Plus, they also manage the color display. 

With that said, if any 1 of them isn’t secure… 

Whether internal or external…

You’re bound to encounter problems with the display. Which includes a red Samsung TV screen. 

#2: Color models of Samsung TVs

Red. Blue. Yellow. 

As you know, those are the primary colors of the color wheel. 

But, the primary colors of light are slightly different. These are: 

  1. Red. 
  2. Green.
  3. Blue.

And together, the 3 colors are called RGB

With that said, you can combine the RGB color in different ratios to make all the other colors. 

And because of that feature, electronic displays like your Samsung TV use the RGB color model. 

In fact, Samsung TVs use RGB pixels to form images on the screen. 

And depending on the red-green-blue ratio on your TV screen, 1 of these would stand out. 

That’s why it’s important to calibrate them correctly. Doing so can lessen issues like your Samsung TV turning red. 

With that, you can enjoy your TV viewing experience. 

#3:  Samsung TV display settings

Speaking of TV viewing experiences… 

Samsung TVs have a variety of display settings to enjoy your movie sessions further. 

I’m talking about these settings: 

Picture Mode 

The setting allows you to optimize the picture quality for different content. 

For example, if you select the “Movie” mode… 

You’ll have richer colors and darker blacks on your screen. Which is just perfect for movies. 

Color Tone 

This 1 adjusts the color “temperature” of your screen. 

And this temperature is either “warmer” or “cooler.”

Like, your TV will appear redder and more yellow when you have a warmer color tone. Whereas the other tone makes the picture appear bluer. 

RGB Mode 

While the previous 2 focus on presets, the RGB mode lets you unleash your artistic side. 


With this setting, you can adjust the RGB ratio manually. And that’s helpful when personalizing your viewing experience. 

And if you need help getting the best picture quality on your TV…

Then you can get right into this helpful guide. 

What causes the red screen on a Samsung TV?

Here are some of the most common reasons that cause the red screen on a Samsung TV: 

#1: Loose TV connections 

When you have loose TV connections, your TV won’t receive signals correctly. 

As a result, your TV would have trouble with its display. And that includes showing an unwanted red screen. 

Now, what do I exactly mean by “loose TV connections?”

I’m primarily talking about: 

  • Damaged cords. 
  • Loosely connected cables. 

But, as I’ve mentioned, there are connections inside the TV. 

And so, the wirings between the mainboard and the T-con board could also lead to the red screen issue. 

#2: Incorrect picture settings

If your Samsung TV’s picture settings aren’t correctly calibrated… 

Some colors could become more vivid than others. 

What do I mean by that? 

Remember, your Samsung TV uses the RGB color model.

With that said, a red screen appears because the RGB ratio is out of proportion. Specifically, the red color overpowers the green and blue hues. 

#3: Overheating 

The color red appears when there is too much heat. 

You know, like in a flame. 

And so, when your Samsung TV overheats… 

It won’t catch on fire, but it’ll produce a red hue on the screen. 

“So, when does my TV overheat?”

That could happen when you’ve been using the TV non-stop for over 5 hours. Especially if there’s no proper ventilation around your TV. 

What does that mean? 

There isn’t enough airflow to lower the TV’s temperature. 

That said, proper ventilation is like helping your TV “breathe.”  

Warning: Overheating could also fry your TV’s internal components. And that can lead to permanent damage.

#4: Display panel issues

Did you know that TV screens are as delicate as a baby? 

With that, even tiny scratches can damage the screen for good. And if that happens, you need to replace the whole TV screen. 

Plus, display panels are prone to internal issues, such as: 

  • Ghosting. 
  • Dead pixels.
  • Image distortion. 

With that said, any of these internal problems can cause a red screen on your Samsung TV.

#5: Outdated TV firmware 

Outdated TV Firmware

The firmware’s job is to control the TV’s system like a brain. 

With that said, outdated firmware won’t do an efficient job in operating your TV’s system. 

And as a result, your TV’s bound to experience problems, such as: 

But, in some cases, outdated Samsung TV software could also make your screen look red.

How do you stop the Samsung TV from turning red?

To stop the Samsung TV from turning red, secure all TV cables and connections first. Then, adjust the TV’s picture settings. Also, improve the ventilation around the TV. Plus, run a pixel test on your TV to spot any potential panel issues. Lastly, check for any due TV software updates.

And so, let me elaborate on these 5 tips for preventing a red screen. Starting with…

#1: Secure cables and connections

For this method, you’re going to check connections outside your TV. 

I’m talking about the external devices you’ve plugged in. 

Now, ensure that you’ve properly inserted each cable into the TV and an external device. 

Plus, you could even double-check by reconnecting them.

Moreover, you can tighten loose screws and replace any damaged cables. 

Then, restart your TV and see whether this fixes your red screen issue. 

If not, simply proceed to the following step. 

#2: Adjust TV’s picture settings

As I’ve mentioned, incorrect picture settings can cause the display to appear red. 

So, follow these 5 easy steps to adjust your Samsung TV’s redness: 

  1. Go to Settings.
  2. Open Picture > Expert Settings
  3. Slide Tint (G/R) value to the left until it’s 0 to reduce redness. 

“The Tint(G/R) is already 0, but my screen is still red.”

Don’t fret. You can simply reset your picture settings and see if it resolves the issue. 

“How do I reset picture settings?”

  1. Go to Settings
  2. Open Picture > Expert Settings > Reset Picture
  3. Confirm Yes.

#3: Improve the ventilation 

Remember, overheating is 1 of the potential culprits of the red screen. 

But the great news is: 

You can simply improve your TV’s ventilation to prevent overheating. 

With that said, here are… 

Useful tips to improve your Samsung TV’s ventilation:

  • Use a cooling fan system
  • Place the TV on an open stand or shelf. 
  • Avoid placing the TV in an enclosed place. 
  • Move TV away from direct heat or sunlight. 

#4: Pixel test 

“What’s the pixel test?”

You see, your TV is made of pixels. 

You know, those small rectangular things you see when you move closer to the screen. 

Now, each 1 of them displays a specific color. And when you put pixels together, you get the whole image. 

It’s like a jigsaw puzzle.

That said, the pixel test checks the color accuracy of every pixel. 

And so you’ll know whether your TV screen is damaged. That’s why it’s showing a red display.

“How do I do the Pixel test?” 

  1. Press the Menu button on your remote. 
  2. Go to Support > Self Diagnosis. 
  3. Open Picture test.
  4. Follow the on-screen instructions. 

During the test, you’ll see if any images are distorted. 

If so, you can contact Samsung’s AudioVisual team here. They’re the best people to help you with the problem. 

#5: Check for Samsung TV software updates

You can follow these 5 easy steps to update your Samsung TV software: 

  1. Connect the TV to the Internet. 
  2. Go to Settings
  3. Open Support
  4. Check Software Update
  5. Select Update Now if available. 

“There’s no due software update.”

Then you could be dealing with a hardware issue.
