Why Samsung TV Is Not Turning On? Red Light Blinking

You have decided to turn on your Samsung TV to relax from a stressful day, or maybe you’ll use it for gaming. All in all, you simply want to sit back and enjoy your evening after a long day at work. You sink into your seat and reach for the remote. 

You click the remote’s power button, but nothing happens. You keep on trying multiple times, hoping something will happen, but it doesn’t. You assume that the batteries could be dead, so you go over and try turning it on with the power button on the TV. 

What you notice is that the red light is blinking as you come close to the TV. The red light turns off after you push the power button on your TV. When you press it again, the light turns back on, but nothing displays on the TV screen.

If you are reading this, this probably sounds familiar, and trust us when we say that we understand how you’re feeling at the moment. This can be very frustrating. When technology fails, it’s crucial to stay calm and consider what is wrong. There are several reasons why your Samsung TV won’t turn on, and we’ll list them below.

1. The Power Supply Is Faulty

If there is an issue with the power supply, your TV will not work. It is a rare situation that the power supply suddenly stops operating without any previous issue. One of the reasons why a power supply may be damaged is due to an electric shock that is caused by a lightning storm.

Your devices (such as TV) and appliances can only handle a certain amount of electricity before they become overloaded and fail, and lightning is a pretty serious problem maker. Lightning can easily strike and travel through the wires in your wall, electrifying everything that is connected straight to the AC outlet, even your TV. This shock of voltage is enough to damage a TV’s circuit boards, and that’s why you should use a surge protector to protect your electric devices.

Thankfully, if you have Samsung Care+, this sort of damage will be covered by your warranty. Depending on the model, a rebuilt power supply/circuit board will cost you roughly $300. A good measurement scale is that the warranty should not exceed 10% of the product’s original price.

Let’s not forget that there is a chance that the power supply was faulty even before you purchased your TV. Of course, this is a rare case, but still, it’s not impossible. If your TV is still under the manufacturer’s warranty, you should be able to receive a free replacement.

2. HDMI Glitch

If you have a game console (PS5, Xbox) plugged into your Samsung TV, there is a chance that the problem lays in the HDMI (input) cable and that it causes your TV not to turn on. This occurs when you turn off your console without first changing the HDMI input source. When you do this, the gaming console may prevent the TV from starting normally. Therefore, be sure to check this also. 

3. Surge Protector Is Broken

Surge protectors can sometimes fail. They’re hooked into an AC outlet, which means they, too, might have issues that influence whatever is connected to them. To discover if your surge protector needs to be changed, try connecting the TV straight into the wall. If you don’t have a surge protector, just ignore this step.

4. Wrong Source Is Selected

Selecting the wrong source is due to human error and is a very common mistake. It’s possible that your TV isn’t switching on because you’ve picked the wrong source or the source isn’t correctly connected.

Step-by-Step How To Fix Samsung Red Light

1. Identify the Issue

The first step in fixing the Samsung TV red light problem is identifying the issue and determining why it occurred. To do so, we’ll run through some simple tests to see if the problem is with the TV’s hardware or software. First, we’ll start by the following:

  1. Check if the standby light under the right side of your TV is on, while the TV is turned on.
  2. If yes, switch it on by pressing the Power button on your remote and verify if the light is now off. 
  3. If it turned off, it implies the TV is correctly connected to the power source.
  4. Confirm that the screen is turned on by softly touching the screen with your finger.
  5. If it lights up, it’s indicating that the screen is functioning properly.
  6. However, if the screen does not light up or the light does not turn off, it is likely that your remote, power source, or screen is broken. Another possibility is that you’re having a black screen on your Samsung TV.
  7. You can follow the steps below to repair your television.

2. Powercycle the TV

Corrupted launch settings might prevent your Samsung TV from turning on properly in some cases. To avoid this problem, we’ll power-cycle the TV in this phase to totally remove the launch settings, which will be automatically regenerated by the TV. This can be done by following these steps:

  1. Make sure to unplug the TV completely from the wall outlet.
  2. For at least 15 seconds, press and hold down “Power On” button on your TV.
  3. Be sure to plug the TV back in and then turn it on.
  4. Make sure to check if the problem is still present after you turn the TV back on.

3. HDMI Slots Are Damaged

Another possible reason why your Samsung TV won’t turn ON is that your TV’s HDMI source selection is damaged. If this is the case, you need to unplug any devices that are connected to your HDMI ports. It doesn’t matter if it’s a gaming console (PS4, Xbox), cable box, or something else.

After you’ve disconnected the device(s) from your TV, turn the TV on and see whether it’s working properly. If it does, switch the source to HDMI 1 and plug the spare device into HDMI 2. Lastly, pick HDMI 2 to enter the device’s screen. Don’t forget to switch back to HDMI 1 before turning the TV off.

4. Contact Customer Support

If the solutions from above didn’t help you to resolve your problem, the problem is almost certainly with your hardware. For that reason, you should call Samsung’s customer support immediately and get your TV repaired. You may also file a claim with them if it’s still under warranty. 

Why There Is A Red Light Blinking On Samsung TV?

If your Samsung TV won’t turn on but the red light is on, try power cycling the TV by disconnecting it from the wall and pressing the “Power button” on your TV for 15 seconds. After that, plug the TV back on and turn it on. These instructions will return the TV to factory settings and fix the problem if the launch configuration is compromised.

Another common cause of this is that your TV is linked to the wrong source or isn’t plugged properly, but the TV itself is actually working well. By tapping the screen and seeing if it lights up, you can determine if everything is working properly. If it lights up, the screen is working; but the problem is that there is no picture that can be projected.

Why My Samsung TV Just Flashes? Won’t Turn On

If your Samsung TV won’t turn on and there is a flash on your screen, it’s most likely because the power source has failed due to a defect or there has been damage caused by a lightning storm. You will need to fix your TV or use a warranty if you have Samsung Care+.

Why My Samsung TV Is Not Turning On After Power Outage

If you have a problem with turning on your Samsung TV, be sure to unplug it and press the power button on the TV for at least 15 seconds. Wait 3 minutes before plugging the TV back in and turning it on. If the light is blinking, it means the power source is broken. Power outages are difficult to repair and might lead to the failure of the power source.

Samsung TV Is Not Turning On (Red Light Is Off)

If your Samsung TV won’t turn on at all and the red light isn’t on or blinking, it’s because the TV isn’t receiving electricity. Firstly, try another AC outlet or a different circuit protector when this is the case. Another possible cause is that the power cable isn’t fully connected, in which case you’ll need to give a little push.

If you still have troubles after this, you might need to disperse the TV’s remaining power. Unplug the TV and press the power button for around 30 seconds before plugging it in and turning it on again. It’s unusual for television to stop working suddenly. Even if the circuit board is damaged due to electric shock, the red light should flash to signal that something isn’t right. Call Samsung and explain the problem if the TV still won’t turn on after following these steps.
