9 ways to fix Samsung TV black screen of death


#1: Check the TV’s cable connection

“The LED light of my Samsung TV is on. But the screen is black…”

If that’s the case, perhaps your TV’s cable connection is loose or faulty.

Your TV receives a connection from your streaming device through the cable wire.

So, your TV will fail to receive signals once it gets loose. Causing your Samsung TV’s black screen of death.

Some of its common causes include:

  • Loose cable ports.
  • Inactive power sources.
  • Incompatible cable wire.
  • Improperly inserted cables.
  • Faulty or damaged cable wire.

Given that, you should check your TV’s cable connection. And see if there’s anything that causes the problem.

First, see if the cable wire is properly connected to your TV and its external source. Make sure also to assess whether the cable ports are loose or not.

If there are no problems with the ports, check the cable for visible damages.

Here are some damage signs that you should look for:

  • Bite marks.
  • Exposed wirings.
  • Poorly-bent cable.
  • Burnt or bent plug insert.

If you notice any of these on your TV cable, get a cable replacement immediately.

Buying reminder: Make sure to get one that’s compatible with your TV and streaming device.

“How would I know if the cable port is faulty or loose?”

Try plugging your cable wire into a different port to know whether the HDMI or AV cable port is faulty.

If the black screen on your Samsung TV disappeared, then your previous cable port is faulty.

#2: Change the TV’s input settings

A Samsung smart TV has several input options. Depending on how many cable ports it has.

When you connect an external device to it, you should change your TV’s input settings.

Because if not, your TV will continue to recognize and play its default input.

So, if your Samsung TV has a black screen, it may have the wrong input settings.

To fix Samsung TV black screen, you should change your TV’s input to the correct settings.

Suppose you’ve connected a Roku streaming device to your TV. Make sure to change your TV’s input to “HDMI.”

Here’s how to change the input settings of a Samsung TV:

  1. Press the “Source” button on your Samsung TV remote.
  2. Then, choose the correct input option.

If your TV has several HDMI ports, you may try selecting all the HDMI input options one by one. Doing this will help you determine the correct input.

After this, the black screen on your Samsung TV should disappear.

If not, check whether the connected external device is powered on. As you might have accidentally turned it off while assessing the cable or cable ports.

In some cases, a black screen of death can happen on your Samsung TV due to extremely high or low power voltage.

When your TV isn’t getting its proper amount of voltage, its system can malfunction. Causing your Samsung TV to have a black screen.

Sure, extremely high or low voltages caused by power outages can’t be prevented.

But there’s a way you can effectively handle it. And avoid your Samsung TV from getting affected by it.

To prevent black screens on Samsung TVs, use voltage management devices.

Such devices help protect your home appliances and gadgets from power surges. Preventing them from having further internal damages.

“I was watching TV. Then the screen suddenly turned black!”

The sleep timer is one of Samsung TVs’ advanced features. This feature helps you manage and monitor your screen time. 

It automatically turns off your TV once it has reached its set time or limit.

Once it’s enabled, you won’t be able to use your Samsung TV. Unless you turn off the sleep timer manually.

So, if your Samsung TV screen suddenly went black, check first if the sleep timer is on.

You’ll know if it’s on when you can only access the TV’s menu settings.

“But I don’t remember enabling the sleep timer…”

Well, the sleep timer can be easily accessed on the settings page.

You might’ve accidentally clicked on it while navigating your settings. 

Or you might’ve accidentally pressed buttons on your remote. Causing the sleep timer of your TV to turn on.

If you’re living with your family or friends, they might’ve set the sleep time without your knowledge.

Regardless of which, troubleshooting this problem is easy. So, you shouldn’t worry about it that much.

To resolve the black screen on your Samsung TV, disable the sleep timer.

Here’s how you can do that:

But aside from that, this reduces the brightness of your TV. Helping reduce eye fatigue while watching TV at night or in a dim room.

“Oh, so power-saver mode only reduces brightness. But why is my TV screen black?”

  2. Low: slightly reduces the screen brightness.
  3. Medium: significantly reduces the screen brightness.
  4. High: greatly reduces the screen brightness.
