Samsung TV Won’t Turn On: 13 Best Fixes

samsung tv won't turn on

Start by attempting to reset your Samsung TV if it would not power on. Remove the power cord from the outlet before pressing and holding the TV power button for at least 10 seconds. After a few minutes, plug the television back in and turn it on. 

There are three possibilities: the standby light is red and flashing, the standby light is not working, or the standby light is green. The power supply is broken when you observe blinks on a Samsung TV. It’s a power problem if you don’t see it operating. If the standby light is green, the panel may have a problem.

One of the most aggravating things is arriving home after a hard day and being unable to switch on the television. Even though Samsung technology has traditionally been regarded as one of the most trustworthy, it occasionally fails.

The first and most significant step in the repair process is to determine why the Samsung TV won’t turn on, and the diagnostic findings will reveal the root of the problem. Depending on the severity of the problem, you may need to repair it yourself or get professional assistance.

What would cause the issue “Samsung TV won’t turn on”? 

To figure out why your Samsung TV won’t turn on, look for exterior damage first, then diagnose the hardware component. This can happen for a variety of reasons:

  1. Mode of inactivity: The gadget continues to work even if the red light is on and the display is turned off. To turn the television, hit the power button on the device’s front panel or the remote control.
  2. You’ve messed up the remote control: To begin, replace the batteries and double-check all of the keys. You may always download a particular program – TV-remote – on your smartphone to switch channels and adjust the volume with your regular phone.
  3. The socket is broken: Connect the TV to a different power source if the indication on the control panel does not light up. After that, you may use the device as usual.
  4. The activation of AV, HDMI, or wireless internet connection is most likely to blame for the appearance of this problem. Consequently, the screen displays a picture from a mobile device or laptop. Switch off all devices and verify all connected HDMI to VGA converters to restart watching terrestrial TV.
  5. Signal strength is weak: Only a black screen is visible on the TV screen owing to a poor signal, which is frequently caused by bad weather conditions such as severe precipitation, thunderstorms, and so on. Do not take action now; the broadcast will most likely restart in a few hours.

You don’t need specialized equipment to figure out why the TV won’t turn on on your own. Now let’s look at the most common breakdowns that consumers face.

What to do when your Samsung TV won’t turn on?

Samsung televisions are noted for their great quality and feature-rich design. When buying a new television, most people choose this brand over others.

However, certain complications may arise when utilizing your Samsung TV. One such problem is when the television refuses to turn on. This might be aggravating, especially if you look forward to seeing your favorite show’s latest episode.

Take notice of the red light on your Samsung TV to quickly resolve this issue. This red light, which may be located at the screen’s edge, is the standby light. This light may be turned on, off, or blinking. The state of the standby light will determine the troubleshooting procedures you must take.

Let us look into why it isn’t turning on and what you can do to fix it:

Solutions To Fix Samsung TV won’t turn on

  1. Check the power supply
  2. Check for HDMI Glitch
  3. Check for Interference From Other Remotes Or Devices
  4. Test the Samsung Power Button
  5. Check the TV remote
  6. Check your Source Selection
  7. Unplug the TV from the wall outlet
  8. Change the Power outlet
  9. Check for Faulty power cables
  10. Check the Power button
  11. Change Blown Fuse
  12. Change the Faulty capacitor
  13. Contact the nearest service center

Solution 1: Check the power supply

Check the power supply

The small grey brick that connects to the wall and powers your entire TV is your power supply. Your entire TV will cease operating if your power source fails.


  • First, ensure the power supply is linked to a reliable power supply. Unplug it and re-plug it if it isn’t working.
  • Then search for a blown fuse or a tripped circuit breaker supplying electricity to the television. These are near the wall socket where your television is plugged in.
  • If everything appears in working order, it may be time to replace the entire power supply.
  • If this is the case, you should immediately take your television to a repair shop.

However, your power supply may be fine, but your TV is still refusing to switch on for some other reason.

Solution 2: Check for HDMI Glitch

It occurs when your TV gets an HDMI signal (high-definition multimedia interface) from a source other than your cable box, DVD player, gaming system, or Blu-ray player incompatible with the format your TV was meant to receive.

Check for HDMI Glitch

Put another way: attempting to connect your automobile to a tractor-trailer with an improper adapter.

As a result, your TV will sit there and pretend to receive an HDMI signal, but it will neither process nor show anything.

This is a particularly aggravating issue because there is nothing you can do about it except take your television to a repair shop.

To determine if this is the issue with your TV, connect it to another device with an HDMI connection and see if it turns on. If it does, you know that this isn’t the issue.

Solution 3: Check for Interference From Other Remotes Or Devices

Check for Interference From Other Remotes Or Devices

This is a typical reason for television not turning on. Many devices in your house use RF (Radio Frequency) bands, including your Samsung TV.

Garage door openers, baby monitors, wireless network access points, cordless phones, and other electrical equipment may fall within this category.

These devices use the same RF bands as your television and might create interference when in operation. Because of the interference, the TV cannot get a strong enough signal to work.

To resolve this issue, either replace your wireless network access point with a different RF band or unplug any devices that utilize the same RF bands as your TV.

Samsung TV Not Turning On, Red Light Is On

If the indicator is red, but the TV does not come on, it is in standby mode, which is normal and indicates that power is being received. First, use the power button to turn on the TV without using the remote.

In certain cases, the signal becomes green before becoming red again. This signifies that the central processor was built, and the incoming signal to switch on was delivered to other modules. 

The LED can change color anytime, but the television never goes on. An inverter or a transistor is the source of the problem. It is required to call the service center so that the problematic modules may be replaced.

Solution 4: Test the Samsung Power Button

Test the Samsung Power Button

Hold down the power button on the television for at least ten seconds. The power button on your Samsung TV can be found on the back or under the front bezel. Look at the standby indication if the TV does not turn on after pushing the power button on the panel. When the button is pressed, it turns off, indicating that the internal lock has been activated.

It is not essential to rule out the possibility of the button or the loop supplying the connection breaking. If the button physically slips within the panel when pressed and does not click, it has to be replaced. 

You can’t accomplish it independently, so you’ll need to attend a Support Center. If you can switch on the TV this way, the issue might be with your remote.

Solution 5: Check the TV remote

Check the TV remote

If your remote isn’t working, the batteries need to be replaced. Then it would help if you double-checked the keys; some may be stuck and only operate after a few clicks.

If the channels do not turn on the first time, the issue is most likely due to a malfunction of the infrared sensor. Mechanical damage or liquid entry into the gadget causes these issues.

To use the remote to control the TV again, you’ll need to buy a new one or replace it with a smartphone app.

To find out how to reset your remote, read these steps:

  • To see if this is the case, click the Menu button on your remote and then go to the Settings menu.
  • Then select the Info button to see what codes are allocated to your remote under “Infrared Codes.”
  • If there are any new codes, you must contact Samsung and request that they be changed.
  • Don’t allow the fact that this is an easy repair that requires a phone call to deter you from trying these troubleshooting procedures.

It’s possible that resetting your remote won’t help! If the problem persists, you may need to take your television to a repair shop.

Solution 6: Check your Source Selection

If you wish to watch live TV but can’t see anything, make sure you’ve selected the right signal source. An HDMI cable is most likely linked to the TV, which must be switched off and the antenna connection activated.

Solution 7: Unplug the TV from the wall outlet

Please wait one minute. While you’re waiting, double-check that the power cord is securely connected to the back of the television and the wall socket. After one minute, reconnect the TV to the wall socket and turn it back on with the power button.

Solution 8: Change the Power outlet

The power socket where the TV is plugged in may be the source of the problem. If another device is plugged into the same outlet as the TV, try connecting it to a new outlet to see if it solves the problem. If this is the case, you should get your outlets inspected by an electrician.

Solution 9: Check for Faulty power cables

A broken power cord is one of the most common causes of your Samsung TV not turning on. If you have an extra power cord, attach it to your TV to see if it fixes the problem. If not, it’s probably time to seek professional assistance.

Solution 10: Check the Power button

If the plug is working properly, the power button on the television should be checked next. The button can sometimes become caught in the “off” position and refuse to switch on no matter how hard you press it. If this is the case, the power button will need to be replaced.

Solution 11: Change Blown Fuse

A blown fuse might cause your Samsung TV’s inability to switch on. Look for a red light on the back of the TV to see whether this is the case.

If the indicator is red, the fuse is still good; all you need to do is change the power cord. However, if there is no red light, the fuse has blown, and you will need to replace it.

A screwdriver and a new fuse are required to replace the fuse. To begin, remove the TV’s back panel. Then look for the blown a fuse in the fuse box. Remove the old fuse and replace it with a new one after discovering it. Finally, replace the back panel and plug in the television.

Solution 12: Change the Faulty capacitor

Check the power cable to ensure it’s plugged in correctly if your TV won’t turn on. If it doesn’t work, try disconnecting and replugging the television’s power cord. This frequently resolves the issue.

Change the Faulty Capacity

If nothing of these options works, the issue is most likely a faulty capacitor. This is a more significant issue that will necessitate the services of a professional technician. If your TV is under warranty, call the retailer who sold it to you, and they will send someone to fix it.

If none of these suggestions work, it’s conceivable that the problem is with the TV itself, in which case you’ll need assistance from a professional.

Solution 13: Contact the nearest service center

If you’ve done everything else and your Samsung TV still won’t turn on, your best bet is to contact the service center, whose technicians will be able to rapidly identify the source of the problem and restore the device’s proper functionality.

To diagnose the problem, they would have professional equipment and licensed software at their disposal, such as spacers, multimeters, oscilloscopes, and so on. 

Only a skilled expert can fix the Samsung TV’s hardware failure. An average user will be able to tackle external character difficulties. Disassembling a gadget on your own is not a good idea, especially if you don’t know what you’re doing.

Samsung Smart TV software issues are also not always easy to fix. You must first download the firmware and store it on a USB flash drive or the built-in hard disc to upgrade it. Not every user will be able to complete this challenge.

Engineers at the service facility have specialized equipment and know-how to remove the television correctly. If you’ve exhausted all other possibilities, it’s time to contact Samsung’s support team.

Samsung TV won’t turn on, and the Red Light Flashes

If the TV does not turn on and the indicator blinks, the power supply is the source of the problem. A continual red flashing light indicates a failure, but you must first identify the problem, which is challenging.

A detailed diagnostic is carried out to discover the reason for the emergence of a flashing red light on the television.

The power adapter is verified with an oscilloscope, and the effectiveness of the converter on the motherboard is also evaluated.

When the red light flashes on your Samsung TV, it’s typically due to voltage issues, which is why it won’t switch on. In the contact circuit, for example, a short circuit has occurred. The simplest approach to test is to detach the power supply from the main board, then plug in the power supply board. 

If the power supply is working properly, you should see some lights in the screw holes, indicating that the problem is not there. If no lights appear on the supply board, proceed to the mainboard and repeat the process. If this is the case, the panel might have a problem.

Samsung TV won’t turn on, and the standby light is green

If the indication is green, but the television does not turn on, the professionals will do a complete examination. The test begins with thoroughly examining the motherboard with specific equipment to assess the incoming voltage.

In addition, instructions for illuminating indicators, turning on the TV, and other functions are being tried. When the LED illuminates, showing that it is operational, but no signals from the main board are present, this might indicate software issues.

Try using a remote control or tapping a button on the main panel to switch on the device.

The damaged component on the motherboard is replaced to solve the hardware issue. If the voltage is in perfect working condition, the experts will reset the user settings before installing the latest software.

What if my Samsung TV won’t turn off?

If the television will not turn off, it is due to a node issue.

For example, if you utilize a liquid crystal matrix device, the factors will drastically differ from the identical LED versions. By disconnecting all of your extra plugins, you may see if they’re the source of the problem. 

Any HDMI to VGA converters or external devices connected to your Samsung TV, such as soundbars (excellent selections on this site), speakers, or surround sound systems, might be giving an error code. Unplugging them will allow you to determine if they are the source of your Samsung TV’s inability to turn off.


It might be aggravating to have a TV that does not turn on. The good news is that, as long as a hardware breakdown doesn’t cause the problem, it’s typically simple to remedy.

You should use an automated voltage regulator or a surge protector if you reside in a region where the voltage swings regularly.

In the event of an electrical surge, your TV’s electronic circuits will be protected by the voltage regulator or surge protector. If you take excellent care of your television, it should last a long time.

To avoid overheating, ensure your television is placed in a well-ventilated area. It’s critical to clean your TV regularly to avoid dust accumulation. Before disconnecting the TV, please turn it off and let it cool down for a few minutes.

Wipe the frame and screen with a microfiber cleaning cloth to clean them. Wipe the frame and screen of the television as lightly as possible. If you don’t notice any results, dampen your microfiber cleaning cloth with distilled water and gently wash the frame and screen. Before plugging the TV back in, let it dry fully.

If it doesn’t work, try disconnecting the TV and then plugging it back in for a few minutes. If nothing of these options works, you may need to seek professional assistance.

What Does A Flashing Red Light Mean?

It’s possible that your Samsung TV won’t switch on for various reasons. A flashing red light normally means the TV is getting electricity, but the display might have a problem. A solid red light indicates that the television is in standby mode. In any instance, troubleshooting instructions should be found in your TV’s handbook.

What’s The Difference Between A Flashing And Steady Red Light?

A flashing red light on your Samsung TV typically signals that something is wrong with it. This might be due to a problem with the power supply or an issue with the television itself.
If a flashing red light appears on your television, disconnect it and call customer care for assistance.
The constant red light on your Samsung TV indicates it is in standby mode. The television is still hooked into an electrical socket in standby mode but is not switched on. To turn on the television, hit the power button on the remote control or press the power button on the television itself.

What Do 2 Flashing Red Lights Mean?

You might wonder what the two flashing red lights on your Samsung TV indicate if you have one. These lights indicate that the television is in standby mode and can be switched on.
If you notice these lights, it shows your TV is in good functioning order, and you shouldn’t be concerned. If you observe three flashing red lights, however, your TV is having trouble, and you should call a Samsung customer care specialist for assistance.
