A dark screen on your Samsung television might stem from a malfunctioning backlight or a defective T-CON board that requires replacement. The issue becomes particularly troublesome and inconvenient when the TV screen remains black, particularly during your favorite shows. However, there are several potential solutions that I will discuss in a moment.
So, sit tight!
Why is my Samsung TV picture so dark?
The picture on your Samsung TV went dark because of the Ambient Light Detection Function or ECO Sensor on some models.
This feature dims or brightens the screen automatically which Samsung added intentionally to reduce power consumption. With this feature, you’ll notice the TV screen turns brighter in a brighter room and darker in dark rooms.
The good thing is that you can turn off this feature, but that’ll depend on the TV model that you have. It is best to check the manual for the appropriate steps on how to turn off the Ambient Light Detection or ECO Sensor.
How do I get my Samsung TV off dark mode?
Dark mode on your Samsung TV is automatically activated when the room gets dark or dimly lit. This can be resolved by turning off Night Mode and extending Sleep After time.
For reference, here’s how to turn off Night Mode if your TV is in Art Mode:
- Go to the Art Mode Home Screen.
- Navigate to Art Mode Options.
- Choose Night Mode.
- Press Enter.
- Set the Sleep After Time. (It can be set for 5 minutes up to 4 hours.)
How do you fix a dim TV screen?
Here are ways to fix the dim screen on your Samsung TV:
- Turn off the contrast enhancer.
- Disable brightness optimization.
- Disable brightness reduction.
- Disable motion lighting.
If you notice the screen flickering constantly, you might need to disable some energy efficiency features. In any case, if you seem to encounter issues with your Samsung TV, check for software updates as it may help resolve the issue.
How do I fix my TV backlight?
Backlight issues occur due to various reasons such as water or drop damage or a defective component. Still, it’s important to diagnose the issue before replacing the TV backlight.
Here are simple fixes to try:
- replace all of the LED strips
- replace some LED strip
These are the steps:
- Open the back of the TV by unscrewing the screws. There should be between 15 to 20 screws depending on the TV model.
- Remove the frontal housing and LED panel.
- Take out the bezel that holds the backlight diffuser in place. This will give you access to the backlight.
- Test the LED lights and remove the faulty ones from the strips. Replace with new ones.
- Reassemble the TV.
Realizing that a whole new platform was needed, the design group developed the concept of a smart
diary that featured a pen interface and a five-and-ahalf-inch screen.
IMPORTANT: If you’re unsure what to do or how to do the steps properly, it is best to call a technician for help.
How do you check the backlight on Samsung?
The best way to check the backlight on Samsung TV is to open a pitch-black picture. If you notice light around the edges of the screen or in the corners, it’s a sign of backlight bleed.
Backlight bleed distract the main image on the screen due to faint lights. It weakens screen display and panels separate more resulting in more noticeable and intense backlight bleeding over time.
Some fixes to try include changing the display setting by reducing the picture setting or adjusting the brightness in your room to compensate for the bleeding.
Summary
When the picture on your Samsung TV suddenly went off while you’re watching your show, there’s no need to worry too much just yet. It is the Ambient Light Detection feature that has been activated to reduce power consumption. Samsung TV screen goes dim or dark when in a darker room and brighter when in a bright room.
However, when the screen begins to flicker or go dark like death, it could be a different issue that may involve problems with the backlight and other hardware issues. Your best bet is to take the TV to the technician or try some DIY methods, only if you’re confident.
