Understanding the Problem: Samsung TV Turns On and Off Repeatedly with a Black Screen

Before rushing into solutions, let us look at the reasons that are making your Samsung TV go off and on with a black screen. 

 

This issue may have a number of underlying issues. Most of these issues are associated with the internal software or hardware of the TV or other connecting devices.

1. Power Supply Issues

 

One of the primary reasons for the Samsung TV turning on and off repeatedly is a malfunction in the power supply. 

If your TV’s power board is improperly functioning, it will execute an automatic function of switching between on and off states. 

This is the case since the television does not succeed at maintaining a steady procession of power supply which results in constant turning off.

This board’s malfunction is dominantly a result of bad capacitors, a power circuit that is put under strain, or even defective internal parts of the television itself. 

Also, if your Samsung TV is plugged into a surge protector, and it is sometimes plugged to a power strip, then the strip could be the issue.

 

2. Faulty or Loose Cables

 

Power cycling may also occur due to loose cables such as the power cord or HDMI cords. 

 

An extreme example would be turning on the TV screen backwards hoping to achieve standby and simply blank the HDMI screen. 

 

This happens with damaged HDMI cables, which happen to be one of the causes of the cables being picked up in the first instance. 

 

All these reasoning applies in the same way to all the cables, more specifically the power cord and the cables with external devices.

3. Firmware Glitch or Software Issue

It is important to note that another common cause for the black screen and the constant on off cycle can be attributed to a firmware malfunction. 

 

This could occur after a TV software update or when the TV’s operating system files get corrupt. 

 

Samsung smart TVs like most electronics today can be described as small computers which have software that runs them. 

 

In such instances, when the software malfunctions or reaches an error, the television may boot on and off over and over displaying a black screen.

4. Overheating

 

Overheating is also a frequently encountered concern as to why your television switches off automatically. 

Samsung TV owners may face such issues because of the overheating internal parts, which makes the television switch off or restart to avert damage. 

Overheating can be caused by a lack of air circulation, fan exhaust blockage, or running the device for too long without rest.

5. External Devices Conflicts

 

Other potential causes include peripherals such as consoles, Blu-ray players, or streaming boxes. 

 

When there is a conflict between a device connected to the TV and the TV, a power cycle or a black screen problem may arise. 

 

For instance, with an external device connected, the TV screen may show a blank picture when the HDMI socket is faulty or wrongly mounted or when the x device cannot communicate with the TV properly.

6. Malfunctioning TV Parts (Bad Capacitors, etc.)

 

In the case that none of the previously mentioned sources appear to be the origin, it is quite possible that the problem lies in the faulty internal one such as a faulty capacitor or damaged power board. 

 

Usually, a qualified technician is necessary for such cases but some workarounds will be discussed in the subsequent section that can be employed prior to seeking professional services.

How to Fix a Samsung TV That Turns On and Off Repeatedly with Black Screen

We now know possible reasons, let’s see how to resolve the issue. Here are a few ways you could try to resolve the problem of Samsung TV blackout but still turning on and off.

Step 1: Check the Power Supply and Cable Connections

 

Before proceeding to more complex repairs, the initial thing is to check for proper TV power supply, and that all the cables attached are fully in. 

 

Power cord connected loosely or connected HDMI cable might easily trigger the situation

What to Do:

Power Cable:

Perhaps disconnection of the TV from a power source for about one to two minutes would rectify the situation while replugging the device may also enable resetting the internal power circuits of the TV.

Cable Connections:

When making connections, bear in mind that everything (HDMI cables, power cables, or any other devices connected) should be connected tightly. 

 

Any cable which is faulty or loosened will need replacing.

 

Samsung televisions plugged in surge protectors or power strips might perform better when plugged directly to the wall sockets in order to rule out any power strip concerns.

Step 2: Perform a Soft Reset

 

Power cycle reset is useful in faulting caused by software, or temporary bugs that cause the TV to cycle and reboot itself.

What to Do:

Cyclically power on and off the TV while unplugged to the power outlet. The instructions on the power cord plug do help explain things further.

 After waiting for approximately 1-2 minutes, one may plug within the same power outlet again.

Retrieve the television remote or the button on the television itself to switch it on.

When experiencing a black screen, a minor TV firmware glitch may be the cause, and a soft reset can usually rectify this.

Step 3: Inspect and Clean the TV’s Vents

 

In the event that overheating is the problem, one must make sure that there is sufficient ventilation for your TV set.

 

The Television may repeatedly turn itself off in order to prevent the internal components from being damaged by excessive heat accumulation.

What to Do:

Switch the TV off and take out the plug from the socket.

Look at the ports located at the back and the HDMI ports found on the sides for any dust or blockages.

Make sure that with the use of a soft dry cloth, there are no obstructions in the vents.

Whenever possible, locate the TV where its airflow is best and is not surrounded by walls on its sides.

Step 4: Disconnect All External Devices

 

It is possible that one of the external devices plugged in your television could be the one that generates conflicts or even a malfunction. 

 

To determine which one of the devices is the issue, you should start off disconnecting all external devices like gaming consoles, Blu-ray players, and sound bars.

What to Do:

Start by switching off the TV and unplugging all the connection cables like the USB cables or the HDMI ones.

Without a device plugged into it, turn on the TV to see whether the black screen problem is still present.

Should the TV function normally, you are better off reconnecting them systematically until you find the device that created the problems.

Step 5: Update or Reinstall TV Firmware

 

When the problem appears to be related to a firmware or software glitch, updating or reinstalling the firmware can resolve the issue.

What to Do:

On the screen of your television, go to Settings > Support > Software Update.

In order to apply the latest software version. Select Update now. The TV will handle the download and installation automatically.

If the set is stuck on standby with a black screen, it is possible that a USB flash drive will be required to perform the update. 

 

Any user who has this model may search for an update on the official Samsung support page.

Step 6: Perform a Factory Reset

A factory restore will return the device to the state and configurations the owner first utilized as well as remove all data. 

That has been input which enables removing annoying software bugs giving an owner problems frequently.

What to Do:

On the television, scroll through Settings > General > Reset.

Provide the PIN (commonly 0000) and acknowledge the resetting process.

This option should only be utilized in very less circumstances because saved settings or preferences will be wiped out.

Step 7: Inspect for Hardware Issues

 

In case the issue still persists after trying all three options illustrated above, the issue could lie with the hardware of the device like malfunctioning of the power board or capacity of the bad elements. 

 

In that instance, it would be advisable to contact a technician.
