  • If the aforementioned red flashing light is present on your Samsung TV, you must reset the appliance.
  • Unplugging your TV from the power source and waiting for precisely 60 seconds are the initial steps towards resetting it.
  • Press and hold the power button for 30 seconds while your television is unplugged.

What is the Reason Behind the Blinking Red Light on Samsung TVs?

Anxiety may set in when the Samsung TV’s bright indication starts blinking red. In the world of technology, the colour red typically denotes a worrying circumstance.

However, it would be foolish to assume that your Samsung TV cannot be fixed simply because it is blinking red. Of course, it cannot be completely ruled out, but it is unlikely.

The three main types of problems that might cause the power button on a Samsung TV to flash red are as follows:

Fix the Blinking Red Light on Your Samsung TV

Connection or source problems: It’s less likely that an HDMI bug or an erroneous source choice is at blame.

TV Reset is required: A power cycle, commonly referred to as a “soft reset,” is required if your TV is malfunctioning as a result of a defective software update.

Improper electricity flow: The most likely explanation is that there is an improper flow of energy, which can be brought on by a surge protector or outlet that isn’t working properly, LED backlights that have shorted out, or a power board with swollen capacitors.

Connection or source problems

Any faults with the source or input on your TV are referred to as “source issues”.

Your TV might not be turning on because, for instance, an HDMI cable is connecting it to your Xbox or PlayStation.

When you turn on some game consoles, a feature known as Anynet+ (or HDMI-CEC) automatically turns on your TV. Although it’s a useful function, it may prevent your TV from turning on until the console is switched on.

This problem frequently arises when you turn off your TV while it is still connected to the same input (for instance, if your Xbox is linked to HDMI1 and you don’t change inputs first).

How to fix Connection or Source problems?

Make sure they are turned on before using any HDMI-connected external devices, such as a game console, Blu-ray player, or other smart device. Your TV may occasionally not come on due to an HDMI fault, but in such circumstances, nothing to be concerned about.

In order to see if the issue stops occurring, you could also choose to unplug the HDMI cord. Once everything starts operating normally again, plug it back in.

It can be as easy as changing the source to something that is connected if your TV is on and the red light is blinking. You might want to try disabling Anynet+ by navigating to HOME > SETTINGS > GENERAL > EXTERNAL DEVICE MANAGER > ANYNET+ > OFF if you’ve previously tried that.

TV Reset is required

Your TV’s red light may be blinking because of a software error or simply because technology is inherently unpredictable. Sometimes, running a software update or just restarting your TV will fix the problem.

Even when your TV is off, it still receives power, and some operations can still be active. So, running a power cycle or reset can assist resolve any lingering problems that might be the root of the blinking red light.

Because turning off your TV is different from unplugging it, even if it has been off for some time, you may still need to perform a power cycle.

How to Samsung Reset TV?

A power cycle may be a successful fix if the blinking red light on your Samsung TV is related to power problems. A power cycle is similar to an electrical reset in that it completely drains the device’s power before restarting it. The steps below should be followed to restart your Samsung TV:

  1. Remove the TV’s plug from the wall and give yourself 60 seconds.
  2. While you wait, press and hold the TV’s power button for 30 seconds to remove any remaining power from its capacitors.
  3. Reconnect the TV’s cable once a minute has passed.

The red light should stop blinking and your Samsung TV should be operating normally once again if the power cycle was successful.

Improper Electricity Flow

There is an inappropriate power flow to one or more parts of your TV, and while there may be a number of causes, they all have something in common. This often happens when your TV is damaged by an electrical surge that damages a component.

A broken power cord, power board (a component that changes the 110V flow from the wall socket into something that the TV can handle), LED backlight strips, or the electricity in your house or apartment are the most common causes of the blinking red light. When this occurs, the TV is either receiving too much or not enough electricity, as shown by the red light blinking.

For instance, when you try to turn on your TV, a blinking red light will show if there has recently been lightning in the area or if the TV’s power supply is outdated or broken.

Malfunctioning Surge Protectors and Electrical Outlets

Sometimes the electrical outlet or surge protector that your Samsung TV is connected to—rather than the TV itself—is the root cause of the red light on your TV blinking. It is conceivable that these external sources were compromised, causing the red light on your TV to flicker.

Damaged LED Backlight Strips

The majority of TVs use a set of LED lights that provide a backlight effect to improve the quality of your TV display. A strip of LED lights is used to provide this backlight, which is independent of your screen.

The red light on your Samsung TV will begin blinking, and the screen won’t work, if the LED backlight strips short out. In this case, you’ll need to either replace the LED strips yourself or pay someone else to do it for you.

Malfunctioning Capacitors/Power Supply

The impairment of capacitors is a common cause of power supply failure in a Samsung TV. Capacitors are tiny but crucial parts of TVs that store and release electricity.

However, when exposed to extreme voltage, these components can expand and malfunction, which will make your Samsung TV flash a red light.

How to fix Issue of Improper Electricity Flow?

Depending on where the power cut occurred, you might need to replace the power cord, power board, capacitors, LED backlights, surge protector, or wall outlet in order to fix the problem with your Samsung TV’s blinking red light.

You must conduct some research and eliminate other potential causes before deciding what has to be replaced. Once you’ve located the problem’s root cause, you can swap out the problematic part to restore your TV’s functionality.

Inspect Your Electrical Outlet and Surge Protector

Checking your surge protector and wall outlet is a smart place to start if you want to save money on replacement parts for your Samsung TV. Try plugging your TV into a new socket, if necessary using an extension cord, to see if the issue continues.

If your TV lights up, your power supply was the problem. If so, you may need to get a new surge protector or have an electrician look at your broken outlet.

Before presuming that the power supply in your TV is broken, it is always prudent to check your outlet or surge protector. This can help you identify the real cause of the issue while also saving you time and money.

Utilize a Voltmeter to Identify the Faulty Components

After ruling out your wall socket and surge protector as the problem’s cause, the power cord, power supply, or LED backlights may be at fault. You can use a voltmeter to pinpoint the location of the power flow interruption before placing an order for a replacement part or utilising your TV’s warranty.

An affordable and simple-to-use instrument that can assist you in identifying the issue with your TV is a voltmeter. Your power cord is faulty if the voltmeter doesn’t register a reading at the outlet. Your power board is damaged if it reads at the outlet but not at the power cord input on the back of the TV.

Even your TV can be opened to do additional diagnostic testing. By taking off the TV’s back panel and positioning your voltmeter correctly, you can check your capacitors and LED backlights.

A voltmeter is not required, but it can be quite useful when attempting to establish whether you require a new power board or cord.

Steps to Replace Faulty LED Backlight Strips

If you’ve established that your TV’s LED backlights are broken, you can source replacement components using Samsung’s spare parts finder, buy new ones, and install them yourself.

There is no requirement for technical knowledge or soldering; all you need is a screwdriver and some patience. You must take out the speakers, boards, screen, and back panel in order to access the LED strips. Once you’ve completed that, changing the LED strips is a simple task.

Instructions for Replacing Blown Capacitors

Check the capacitors on your TV’s power board if you have a suspicion that it is malfunctioning. If you have the required equipment and some soldering skill, you can replace them yourself if they are blown or bloated.

However, it might be advisable to take your TV to a repair shop and have the capacitors replaced properly if you don’t have the necessary tools or skills. Even while it can be more expensive than buying a new TV or power board, it will still be less expensive.

What if None of the above methods works?

It might be time to use the warranty that came with your Samsung TV if you’ve tried all the troubleshooting techniques and the TV is still not coming on.

Fortunately, since a failing power supply is a mechanical issue and wasn’t your fault, the warranty should cover it. However, Samsung only offers a one-year guarantee on their TVs, so if your TV is more than a year old, you might be out of luck.

Samsung will either pay for repairs or send you a new TV at no cost if your TV is less than a year old and you have tried all the other troubleshooting techniques. However, the cost of shipping the damaged TV back to us may be your responsibility.

You can either phone 1 (800) 726-7864 or visit Samsung’s support website and follow the instructions to connect with a person.

Wrapping it up

In conclusion, a blinking red light on your Samsung TV is an indicator of a power-related problem, and before considering the warranty, there are a few things you may take to try and fix it.

There are a number of troubleshooting techniques you may use, including checking the power source and cords, power cycling the TV, attempting various inputs, and turning off Anynet+.

If none of these techniques succeed and your TV is still covered by warranty, Samsung will fix or replace it at no cost to you. Keep in mind to always adhere to safety precautions when working with electronics, and don’t be afraid to contact Samsung support if you require additional help.
