Many times, a malfunctioning wall socket or power cable can cause your TV to keep turning on and off by itself. Fortunately, there are several steps you can take to resolve the problem.
One simple solution to the problem is to power cycle your TV by unplugging it from the wall outlet for 60 seconds. This will delete any temporary memory and reset the main board without causing any harm.
Check the Power Cord
A TV that keeps turning on and off may indicate an issue with its power cord. If your Samsung TV isn’t getting enough juice, it won’t be able to operate properly and will automatically shut down. The power cord connects your television to an outlet and is typically made of durable material for long-lasting connections.
If you find that your power cord is malfunctioning, you may want to replace it. There are various types of power cords available and you’ll need to determine which one works best with your TV.
Your power cord is designed to carry a substantial amount of electricity, which can be used for driving various appliances and electronic devices. It must also withstand extreme temperatures and environments. Composed of two wires with distinct colors–the black (North America) or brown (International) live wire serves as the power source while the white neutral wire acts as the grounding or earth connection.
When fixing a power cord that has become damaged, you must ensure it’s securely connected to the outlet and free of damage. You can check this by feeling the cord with your hand; make sure there’s no visible breakage.
Another thing to check for when purchasing your TV is the connection between its main board and power supply board. Sometimes, a cable that runs from one board to another may short out between these boards, leading to frequent power on/off cycles.
Fortunately, this issue can be quickly and easily rectified by replacing the power cable. You’re likely to find a suitable replacement cable at most retail stores.
It is wise to inspect your power cord regularly, so you can detect any problems before they cause your TV to turn off. Furthermore, using a dry microfiber cloth on the back of your television may improve airflow and ventilation.
You can also perform a factory reset of your Samsung TV to identify which setting is causing the issue. This process will restore all settings back to their original state, eliminating any potential causes for why your television keeps turning on and off. If after trying all these measures and still experiencing problems, contact Samsung customer support for assistance in solving the problem.
Check the Power Outlet
If your TV keeps turning on and off, it could be due to an issue with the power outlet. Electrical outlets (or sockets) are two-sided devices that connect to a power grid in order to deliver electricity directly to your device.
It is essential to inspect the power outlet for damage, such as frayed wires or a broken cord. Furthermore, make sure the plug is securely attached to the wall outlet. If there are additional devices connected to this outlet, ensure they’re plugged in and working correctly.
A malfunctioning surge protector or power cord can disrupt your television’s current supply, causing it to flicker on and off randomly. To confirm if this is the issue, unplug the TV and try connecting it to another power outlet; if this doesn’t solve the problem, you’ll need to replace either your surge protector or power cord.
This is a common issue and can be caused by several things. One of the most likely is your television overheating, causing it to shut off abruptly. Additionally, there’s the possibility that another device is connected to your television such as a cable box or game console.
Another possible explanation for your television turning on and off repeatedly is due to a temporary software issue. In rare cases, your Samsung TV’s internal memory may become overloaded or the firmware of the device may crash – leading to intermittent power cycles until you can resolve the problem.
Power cycling your Samsung TV can help resolve this problem. Doing so will turn off all components, such as its backlight and display, then restart them for normal operation.
If you don’t want to perform a power cycle, try disconnecting all other devices from the television and seeing if that helps identify what’s causing the problem and provides an opportunity for resolution.
Check the Surge Protector
A power surge can have a variety of consequences. One common issue is that your TV may stop working altogether.
This can be a major inconvenience, particularly when using it to watch shows or movies on demand. To combat this issue, make sure that you have installed a surge protector.
Surge protection devices, also referred to as metal oxide varistors (MOVs), absorb excess voltage and redirect it back to the ground wire. They can protect your appliances from getting damaged due to lightning or other types of surges.
These protectors have a clamping voltage, which is the point at which they cause excess electricity to be diverted away from connected appliances. The higher this value, the better protected you are with a surge protector.
Surge protectors are the best way to safeguard your electronic equipment against power surge damage. Not only are they affordable, but having one on hand could potentially save you a lot of money in the future if a power surge damages your electronics.
If your surge protector is not functioning optimally, it could be the cause of the issue with your Samsung TV. To determine whether or not it is to blame, try plugging your television into another outlet and seeing if that fixes the problem. If so, then a defective surge protector likely exists.
The next step is to assess a surge protector’s joule rating. This tells you how many joules it can handle before it no longer provides protection for your equipment.
A reliable surge protector should have a joule rating of at least 2,000. This indicates the amount of protection it can provide and if it will remain effective for an extended period.
Once you know the joule rating of your surge protector, you can make an informed decision whether or not it needs replacing. To do this, keep track of both the amount and intensity of surges that occur.
Power surges can often cause minimal damage to your television set; however, they can do a lot of harm if they happen frequently. Furthermore, they could burn out the components inside your television and render it completely unusable.
Check the TV Settings
Your Samsung TV may begin to turn on and off without you pressing the button, signaling an urgent problem that must be addressed.
The initial step to solving this problem is checking the TV settings. These allow you to control your device with the remote and connect it to other devices, and it could be that some of these connections are causing the TV to keep turning on and off randomly.
Some of these settings are automatic, meaning they may start and stop without you knowing. You can disable or turn off this feature by changing its setting to Off or simply restoring your device back to defaults.
If you can identify the settings causing your issue, try disabling or removing them completely. This will stop your device from turning on and off by itself; however, keep in mind that doing so will delete all personalization features and apps.
Another potential cause of your problem may be a non-permanent memory issue on your Samsung TV’s main board. Power cycling or cold booting your television will clear out any errors with non-permanent memory and reset its main board without affecting personal settings.
This is a more drastic solution than other troubleshooting techniques, but it could be worth trying if the other solutions haven’t worked. While it will remove any personalization features or downloaded apps on your device, this quick fix won’t leave any lasting harm behind.
If you suspect an electrical problem is to blame for your TV’s frequent powering off, check to see if your wall outlet is defective or damaged. This could be caused by an electricity surge, lightning strike or faulty connection between cable box and power supply.
Furthermore, if your home has poor ventilation or a warm room, this could be contributing to your TV turning off frequently. To resolve the problem, improve ventilation in your home or direct a fan towards it; hopefully this will eliminate the issue altogether.
