Many Samsung Smart TV owners have reported this issue, leaving them frustrated and confused. In this in-depth article, we’ll delve into the possible causes of this problem and provide you with practical solutions to resolve it.
Understanding the Basics: What Causes a Samsung Smart TV to Flicker or Turn On and Off?
Before we dive into the troubleshooting process, it’s essential to understand the underlying causes of this issue. A Samsung Smart TV’s flickering or turning on and off can be attributed to a combination of hardware, software, and environmental factors.
Hardware-Related Issues
- Faulty or Loose Connections: A loose or faulty connection between the TV’s internal components, such as the power supply, mainboard, or backlight, can cause the TV to malfunction and result in flickering or turning on and off.
Software-Related Issues
- Firmware Glitches: Samsung Smart TVs run on software that can occasionally develop bugs or glitches, leading to the flickering or turning on and off issue.
Environmental Factors
- Electrical Interference: Electromagnetic interference (EMI) from nearby devices, such as cordless phones, baby monitors, or microwaves, can affect the TV’s performance and cause it to malfunction.
Troubleshooting Steps to Resolve the Flickering Issue
Now that we’ve covered the possible causes, let’s move on to the troubleshooting steps to help you resolve the issue.
Step 1: Power Cycle Your Samsung Smart TV
Perform a simple power cycle by turning off your TV, unplugging it from the power outlet, waiting for 30 seconds, and then plugging it back in and turning it on. This step can sometimes resolve the issue by resetting the TV’s internal components.
Step 2: Check for Loose Connections
Inspect the TV’s internal components, such as the power cord, HDMI cables, and other connections, to ensure they are securely connected. If you find any loose connections, tighten them firmly.
Step 3: Update Your TV’s Firmware
Check if there are any firmware updates available for your Samsung Smart TV. Updating the firmware can resolve software-related issues, including the flickering or turning on and off problem.
Step 4: Disable HDMI-CEC
HDMI-CEC (Consumer Electronics Control) is a feature that allows devices connected to your TV to control each other. However, it can sometimes cause conflicts and lead to the flickering issue. Try disabling HDMI-CEC on your TV and connected devices to see if it resolves the problem.
Step 5: Reset Your TV to Factory Settings
If the above steps don’t work, you can try resetting your Samsung Smart TV to its factory settings. This will erase all your customized settings and apps, but it can also resolve the issue.
Additional Troubleshooting Steps for Advanced Users
If the above steps don’t resolve the issue, you can try the following advanced troubleshooting steps:
Step 6: Check for Capacitor Issues
In some cases, a faulty capacitor in the TV’s power supply or backlight can cause the flickering issue. If you’re comfortable with DIY repairs, you can try replacing the capacitor. However, this step requires technical expertise and is not recommended for beginners.
Step 7: Check for Backlight Issues
The backlight is responsible for illuminating the TV’s screen. A faulty backlight can cause the flickering issue. If you suspect a backlight problem, you can try replacing the backlight or the entire LED panel.

Why does my Samsung Smart TV keep turning on and off?
This frustrating issue can be caused by a variety of factors. It’s possible that there’s a problem with the TV’s power cycling, which can be triggered by a faulty capacitor or other electrical component. Additionally, software glitches or conflicts with other devices connected to the TV can also cause the on-off cycle.
In some cases, the issue might be related to the TV’s settings or configurations. For example, if the TV is set to turn off automatically after a certain period of inactivity, it may be mistakenly detecting inactivity and shutting down. It’s also possible that the TV’s power saving features are causing the issue. To troubleshoot the problem, try disabling these features and see if the issue persists.
Is it possible to fix the on-off issue myself?
Yes, it’s possible to try and fix the issue yourself before seeking professional help. The first step is to try restarting the TV and seeing if the issue resolves itself. You can also try unplugging the TV from the power outlet for 30 seconds and then plugging it back in. This can sometimes reset the TV’s electrical components and resolve the issue.
If the issue persists, you can try updating the TV’s software or resetting it to its factory settings. You can also try disconnecting all external devices and seeing if the issue is resolved. If none of these steps work, it may be worth contacting a professional TV repair technician or the manufacturer’s customer support team for further assistance.
Can a firmware update fix the on-off issue?
Yes, a firmware update can potentially fix the on-off issue. Firmware updates often include bug fixes and performance improvements that can resolve software-related issues. If the issue is caused by a software glitch or conflict, updating the firmware may resolve the problem.
To update the firmware, go to the TV’s settings menu and look for the “Software Update” or “Firmware Update” option. Follow the on-screen instructions to download and install the update. Make sure the TV is connected to the internet and that you have a stable connection before attempting the update.
Can other devices connected to the TV cause the on-off issue?
Yes, other devices connected to the TV can potentially cause the on-off issue. If a device is malfunctioning or is not compatible with the TV, it can cause the TV to shut down or turn off unexpectedly.
Try disconnecting all external devices from the TV and see if the issue resolves itself. If the issue persists, try reconnecting the devices one by one to isolate the problem. You may need to update the firmware of the external device or replace it if it’s found to be malfunctioning.
Can I replace the TV’s power board to fix the issue?
Yes, in some cases, replacing the TV’s power board may fix the on-off issue. If the issue is caused by a faulty capacitor or other electrical component on the power board, replacing it may resolve the problem. However, this should only be attempted by a professional TV repair technician who has the necessary expertise and experience.
Replacing the power board can be a complex and delicate process, and if not done correctly, can cause further damage to the TV. It’s also important to diagnose the issue correctly before attempting any repairs, as replacing the power board may not necessarily fix the problem.
Is it worth repairing my Samsung Smart TV or should I replace it?
The decision to repair or replace your Samsung Smart TV depends on several factors, including the age and condition of the TV, the cost of repairs, and the cost of a new TV. If the TV is relatively new and the issue is caused by a faulty component, it may be worth repairing it.
However, if the TV is old or the repair cost is high, it may be more cost-effective to replace it with a new one. Additionally, if the issue is caused by a software problem that cannot be resolved through updates or resets, it may be best to consider replacing the TV. It’s always a good idea to consult with a professional TV repair technician to get their expert opinion before making a decision.
Can I prevent the on-off issue from happening in the future?
Yes, there are several steps you can take to prevent the on-off issue from happening in the future. Regularly updating the TV’s firmware and software can help resolve software-related issues. Additionally, keeping the TV clean and dust-free can help prevent overheating, which can cause the TV to shut down.
It’s also a good idea to use a high-quality power strip or surge protector to protect the TV from power surges or electrical spikes. Finally, avoiding overheating by keeping the TV in a well-ventilated area and not blocking the vents can also help prevent the issue. By taking these precautions, you can help extend the life of your Samsung Smart TV and prevent the on-off issue from occurring.
