How To Fix A Blinking Red Light On Your Samsung TV Remote In Few Easy Steps

A television remote control is necessary to allow us to easily scroll among channels, adjust volume, and control other settings on our Samsung televisions. 

It can, however, be aggravating when the remote suddenly stops working and a blinking red light displays. Many Samsung TV owners are perplexed about why their remote is malfunctioning and how to address it.

In this post, we will investigate the causes of the blinking red light on your Samsung TV remote and look into possible remedies to get it working again. 

So, if you’re having this problem and looking for solutions, keep reading to learn about the various causes and troubleshooting techniques that can help you restore control of your TV viewing experience.

Low Battery

A low battery is one of the most common causes of a blinking red light on a Samsung TV remote control. When the remote’s batteries run out, it could become unresponsive or exhibit abnormal behavior. This can be aggravating, but fortunately, it has a rather straightforward solution.

To resolve the problem caused by a low battery, replace the batteries in your Samsung TV remote control as follows:

  • Locate the battery compartment on the remote control’s rear. It is typically found near the bottom or on the back panel.
  • Slide the top of the battery compartment or remove it with a tiny screwdriver.
  • Take note of the type of battery required by your remote control. The majority of Samsung TV remotes use AAA or AA batteries.
  • Remove the old batteries from the container and properly dispose of them.
  • Replace the batteries in the compartment, ensuring they are perfectly oriented according to the polarity markings.
  • Securely close the battery compartment cover.

When you replace the batteries in your Samsung TV remote, the blinking red light should cease, and the remote should resume normal operation. High-quality batteries are recommended for maximum performance and longer battery life.

Blocked Remote Sensor

A clogged remote sensor is another common cause of your Samsung TV remote control not working and flashing red. The remote sensor on the TV accepts remote control signals and allows it to communicate with the television. When the sensor is obstructed, the signals cannot reach the television, resulting in inactivity or blinking red light on the remote.

To resolve this issue, use the following tips to unblock the remote sensor:

  • Ensure no items are in the way of the remote control and the TV’s remote sensor. Furniture, decorations, or other equipment put in front of the TV are common impediments.
  • Move any objects away from the front of the TV to remove any physical impediments. This will allow the remote control signals to reach the sensor without being obstructed.
  • Examine the remote sensor for any dust or dirt. Dust particles might collect on the sensor over time, impairing its performance. Gently clean the sensor with a gentle, lint-free cloth to remove any dirt or smudges.

This should cure the blinking red light issue and restore appropriate remote control-to-TV connectivity.

Pairing Issues 

Aside from a low battery and a blocked remote sensor, pairing issues can cause remote control issues with a blinking red light. The remote control can unpair or lose its connection with the television at any time, resulting in an unresponsive or malfunctioning remote. 

If you’re having this problem, use these procedures to re-pair the remote control with the TV:

  • Check that the television is turned on and working properly.
  • Press and hold the “Power” and “Return/Exit” buttons on the remote control for approximately 3-5 seconds. This starts the pairing procedure.
  • Look for a message or indicator on the screen that the remote control is being linked. The particular instructions may differ based on the model of your Samsung TV. 
  • Consult the TV’s user manual for any extra steps or specialized information.
  • The remote control should resume functionality, and the blinking red light should stop after the pairing process is complete.

Software Updates 

Outdated software on your Samsung TV can potentially cause remote control troubles, such as the blinking red light. Software updates are critical because they frequently include bug patches, performance improvements, and compatibility improvements. 

If your television’s software is outdated, it might fail to recognize or respond to remote control signals. To resolve this issue, perform the following procedures to update the TV software:

  • Check that your television is linked to the internet. Connect to a stable Wi-Fi network or use an Ethernet connection.
  • Press the “Menu” button on the TV remote control.
  • Using the arrow keys, navigate to the “Settings” or “Support” section, and then pick “Software Update” or a similar option.
  • Select “Update Now” or “Check for Updates” from the menu. The television will then look for available software upgrades.
  • If an update is discovered, follow the on-screen instructions to proceed with the software update procedure. The update may take some time to download and install.
  • When the update is finished, restart your TV to see whether the remote control issue with the blinking red light has been repaired.

Infrared Interference

Infrared interference is another possible reason for remote control problems with a blinking red light. Infrared signals used by most TV remote controls can be interrupted or obstructed by specific objects or light sources. Because of this interference, remote control signals may not reach the TV’s sensor, resulting in a defective or unresponsive remote control.

Consider the following ways to eliminate infrared interference and improve the performance of your remote control:

  • Adjust the TV settings: Some Samsung TVs allow you to change the sensitivity of the infrared sensor or enable functions such as “Remote Control Signal” or “IR Blaster” in the settings menu. Examine your TV’s settings to determine if there are any possibilities for improving remote control performance.
  • Remove any physical impediments: Make sure there are no physical impediments between the remote control and the TV’s infrared sensor. Remove any things that may be blocking the line of sight between the remote and the TV, such as decorations, plants, or furniture.
  • Remove other objects: Other electronics emitting infrared signals, such as fluorescent lights, halogen lamps, or other remote-controlled devices, can interfere with remote-control operation. Move such devices away from the TV or turn them off for a short period of time to see if it improves remote control functionality.
  • Dim the lights: Infrared radiation from bright ambient lighting, particularly some types of LED lighting, might interfere with remote control signals. Dim or alter the lighting in the room if possible to reduce interference.

Note:- If the blinking red light problem persists despite completing these procedures, it is best to contact Samsung customer care for further assistance or, if necessary, consider purchasing a replacement remote control.


A flickering red light on your Samsung TV remote control can signal a number of problems that could impair its functioning. 

You can troubleshoot and resolve the problem by identifying possible causes, such as a low battery, a blocked remote sensor, pairing issues, software updates, and infrared interference. 

Taking the appropriate actions to fix these issues can assist in restoring the normal operation of your remote control, ensuring a smooth TV viewing experience.
