Why Is My Samsung TV Dark on One Side? [Answered]

Do you own a Samsung TV and notice it is dark on one side? It can be confusing and frustrating to try and figure out what’s happening with your television. Fortunately, there are solutions to fix Samsung television shadows. Read on to learn more about Samsung TV dark shadow on one side and tips on how to fix it.

Why Is My Samsung TV Dark on One Side?

A Samsung TV with a black side could be due to several reasons. Some of the possible explanations for Samsung TV dark shadow on one side include the following:

1. Backlight Issues

Check the backlight settings if your Samsung TV is dim or dark on one side. You can adjust the brightness, contrast, and gamma settings to improve the picture. Also, ensure the TV isn’t too close to a bright light source, such as a window or overhead light, which can cause glare or shadows on the screen. If adjusting the settings doesn’t solve the problem, you may need to replace the backlight. 

2. Burn-In

Samsung TVs are susceptible to burn-in, leaving one side of the screen darker. It happens when a picture is shown on a screen for too long, causing the pixels in that area to stay permanently locked at a single brightness or color. That may make the affected area look darker or lighter than the rest of the screen.


3. Debris, Moisture, or External/On-Screen Dirt

If your Samsung TV appears dark on one side, it could be due to dirt, dust, or moisture built up on display. These problems can occur when you move the TV from one location to another or place them in a high-humidity environment. In this case, the debris and moisture will affect how light is spread across the TV, resulting in a dark spot.

You can use a damp cloth and a mild cleaner to clean the display. Wipe gently, as harsh scrubbing can cause damage. Wondering how to clean a Samsung TV screen? You should use an anti-static cloth and a small amount of glass cleaner.

4. Pixel Failure

The pixel produces the colors and images on the TV screen, and its failure might make the impacted area appear dark. Sometimes, you may need to fix pixel failure by changing the visual settings or replacing a faulty component.

5. Manufacturing Defect

A manufacturing defect may make your Samsung TV dark on one side. If your Samsung TV black screen does not fix through troubleshooting, you will need to contact Samsung for service or warranty support. Note your TV model when contacting customer service for Samsung TV screen problems.

6. High Temperature

When you expose the television too high temperatures for an extended period, it can cause the display to become dark on one side. That’s because heat affects the TV’s internal components resulting in an uneven backlight distribution.

You will need to measure the TV’s temperature to check if this is the case. Some models come equipped with temperature sensors to help you determine when your TV is getting too hot. You also may get the TV’s temperature by going to the diagnostics menu.

7. Blunt or Mechanical Damage

Damage to the LCD panel or its components can cause a dark area on your Samsung TV. In some cases, blunt force impact can cause a dark spot or shadow on the screen. That occurs when you drop something on the TV’s display.

The best way to check for this type of damage is to open up the TV and inspect the components for any visible signs of damage. If you’re not comfortable doing it yourself, contact a qualified technician.

8. Wrongly Mounted TV

Incorrect mounting might cause your Samsung TV to appear dark on one side. Poor mounting results in uneven distribution of backlighting across the screen, and that could lead to one side of the screen appearing darker than the other.

To diagnose this issue, look at the TV’s position and ensure it’s properly mounted. If it appears loose, try adjusting it and see if that fixes the problem. If changing the position doesn’t fix the issue, you may need to call a professional for assistance.
