What is the Red Blinking Light on the Samsung TV Remote?

samsung tv remote control

You may notice a red blinking light on your Samsung smart remote occasionally flashing when you pick up the device or press any buttons.

This visual indicator serves an important diagnostic function – alerting users to potential connectivity problems between the remote-control handset and the Samsung television itself.

Essentially, the blinking red light signifies your remote cannot properly transmit infrared signals to the IR receiver sensor on your TV at that moment.

This breakdown in critical one-way communication triggers the red warning flash.

There are a range of possible root causes for the connectivity failure ranging from an obstruction blocking sensor line-of-sight to incorrectly paired devices to low battery power on the remote.

In the following section, we’ll look at all the causes in detail and also provide you with troubleshooting steps to resolve each one.

Samsung Remote Red-Light Blinking: The Most Common Reasons and How to Fix It

Is your Samsung remote blinking? If yes, then there are several reasons behind this problem. In this section of this guide, we’ll look at some of the most common causes and how to resolve them.

1. Lack of Proximity 

A lack of proximity between the Samsung remote control and the Samsung smart TV can cause connectivity issues that result in the remote blinking red.

Specifically, if the remote is too far away from the TV’s infrared sensor, the signal from the remote will be too weak for the TV to detect. This communication problem causes the remote to blink red.

To fix a lack of proximity issue with your Samsung remote blinking red:

  1. Move closer to the TV with the remote control and observe if the blinking red light stops. The ideal distance is 1-2 feet away. 
  2. If moving closer stops the blinking, you have confirmed proximity was the cause. You now know you simply need to use the remote closer to the TV within that 1-2 foot range.
  3. If the light continues blinking when closer, try raising your hand with the remote right in front of the TV’s infrared sensor. This helps focus the signal directly on the sensor. 
  4. If the light stops when your hand is near the sensor, it likely means the sensor has weakened over time and struggles to detect signals from further away. Consider having the TV serviced to restore full sensor functionality.
  5. As a temporary fix until the sensor is strengthened, continue using the remote very close to the TV’s sensor, within 1 foot or less.

2. Connectivity Issues

Connectivity issues between the Samsung TV and the remote control can cause the remote to blink red.

This stems from the devices being unable to communicate properly with one another, either from initial pairing problems or from a pairing connection that has been lost over time. 

A disrupted transmission signal, whether from a software glitch, wiring fault, or lost pairing, prevents the TV and remote from talking effectively.

This breakdown in communication causes the remote control’s red light to blink when buttons are pressed as it tries unsuccessfully to connect with the now unlinked TV.

The core underlying cause is the remote and TV being unable to transmit signals back and forth to each other.

Resetting and repairing this communication line by troubleshooting what is disrupting connectivity will solve the remote blinking red issue.

To troubleshoot and fix connectivity issues, follow the detailed steps outlined below: 

  1. Check if there is a corresponding flashing light on the TV’s infrared receiver when using the remote. No flashing light indicates a one-way communication issue.
  2. Try resetting the connection by pressing the B and C buttons on the remote simultaneously and holding for a few seconds. 
  3. Observe if the TV’s flashing light responds, indicating a successful reset of the connection.
  4. If the TV light does not flash, use the remote to enter code 981 on the Samsung TV to reprogram and reconnect the devices. 
  5. Alternatively, you can re-pair the devices by turning on the TV using its power button, holding the remote 1-2 feet away facing the IR receiver, then pressing and holding the Return and Play/Pause buttons simultaneously for 5 continuous seconds.
  6. Keep holding the buttons until you see “Connecting to Samsung Smart Remote” on the TV display, initiating the pairing process. 
  7. When you see the on-screen notification change to “Pairing Complete,” release the held buttons. 
  8. A remote control and battery icon on the TV indicate connected status. 
  9. Test remote functionality after following the above steps. If issues continue despite resetting, reprogramming, and re-pairing, further electrical testing is needed to pinpoint communication faults.

If you are unable to restore communication between the devices yourself through resetting, reprogramming, and re-pairing. Then you should consider hiring a professional to diagnose and fix the problem.

3. Weak or Damaged Batteries 

Weak or damaged batteries in your Samsung remote control can cause connectivity issues that result in the remote blinking red when buttons are pressed. 

The batteries in your Samsung remote provide power to the remote so it can transmit infrared signals to the TV.

So, if the charge becomes too low or the batteries get corroded, the remote will, in turn, lack sufficient energy to maintain communication with the TV. 

As a result, the TV is now unable to receive the remote’s signals, and the remote blinks red as it tries to connect unsuccessfully.

This often comes as a surprise since even very feeble batteries can power remote basic functions for months before fully dying. This is why most people often forget or neglect to check them.

However, it is important to check the condition of your batteries from time to time as dead or damaged batteries can leak fluids capable of irreparably damaging your remote control.

If you suspect weak or damaged batteries as the cause behind the red light on your remote, follow these troubleshooting steps to replace the batteries:

  1. Remove the existing batteries from the Samsung remote. Take note of their orientation and directional arrow for correct realignment later.
  2. Insert the batteries into another device like a radio and check if they function properly there. If those devices work fine, continue troubleshooting. If they do not, the culprit is confirmed to be battery failure. 
  3. Procure two new AA alkaline or lithium-ion batteries for your Samsung remote. Avoid previously used batteries.
  4. Check the battery compartment for the positive (+) and negative (-) signs denoting battery alignment.
  5. Align your new batteries according to the marked positive and negative sides noted above. Follow the directional arrow from earlier observation. 
  6. Reattach the Samsung remote battery compartment cover.
  7. Test remote functionality by pressing buttons and observing TV response. The blinking red light should now be resolved.

4. Obstructions Blocking Remote’s Signals 

The Samsung television remote control sends out infrared (IR) signals to communicate commands to the TV’s IR receiver sensor. 

When objects physically obstruct the path between the remote and the sensor, those signals cannot be transmitted.

Things commonly found around living room TVs like sound bars, books, decor items, furniture, or even accumulated dust/dirt can act as barriers. They block the IR beam from reaching the TV receiver, which requires a clear line of sight for signal detection. 

When the sensor fails to pick up these disrupted signals due to an obstruction, users experience remote button presses resulting in a blinking red light rather than the expected TV response.

If there’s an obstruction between your remote and the TV’s IR receiver, follow these steps to resolve it:

  1. First, inspect the path between the seated remote usage position and your TV’s IR sensor. Look for sound bars, media players, books, vases, and other items intruding across that space.
  2. Carefully shift or remove identified objects to create a clear line of sight to the TV sensor from the remote control’s orientation when in use. 
  3. If you cannot move permanent room features, consider repositioning your TV instead so the space facing its IR receiver is kept clear.
  4. Use a dry microfiber cloth to gently wipe away any dust or dirt that may have accumulated on the IR receiver sensor itself. Avoid using liquids.  
  5. Test if your remote triggers expected TV responses after pressing buttons, now that signal obstructions have been eliminated.

5. Stuck Buttons

The buttons on your Samsung smart remote control can sometimes become physically stuck and prevent smooth pressing or release.

This occurs when dirt, grime, food debris, or other environmental buildup gets lodged under buttons over time. Oxidation from moisture exposure can also cause stickiness. 

When one or more buttons are stuck, they remain perpetually activated on the remote’s circuit board, which can disrupt signals to the TV and cause remote malfunctions like the blinking red light. 

If enough buttons stick, the remote may become entirely unresponsive because the maximum simultaneous signal output would have been reached.

This frequently happens to commonly used buttons like volume and playback since they endure the most presses.

To troubleshoot and fix stuck remote buttons causing blinking red or lack of TV response:

  1. Press each button individually multiple times in quick succession while monitoring the button’s return responsiveness. Take note of any button that feels sticky or fails to spring back into place swiftly.
  2. Gently open the remote control by removing the battery cover and any screws. Carefully detach the front and back halves to access internal parts. 
  3. Use a rubber eraser to vigorously rub stuck buttons and loosen accumulated grit and grime buildup so it falls away when flipped over.
  4. Dip a cotton swab in rubbing alcohol (isopropyl alcohol) and wipe it over buttons and electrical contacts to dissolve sticker residue or oxidation. 
  5. Clean the rubber button pads separately with warm soapy water and a soft cloth to remove deeply embedded dirt or sugars contributing to sticking. 
  6. Ensure that no moisture remains before reassembling the remote once fully dried. Once you are done, test the remote for smooth responsive buttons that no longer stick.

6. Possible Damage

Samsung smart remote controls contain intricate internal circuitry and components that enable signal transmission to the TV.

Like any electronic device, wear and tear or accidental impacts can damage the hardware inside the remote over time. 

External cracks or dents visible on the remote may signify internal damage not visible from the outside.

Things like drops, liquid contact, or battery corrosion can break down remote integrity.

Any degradation of internal wires, sodder points, or circuit boards can disrupt connectivity leading to issues like blinking red lights when buttons are pressed instead of remote commands properly registering with the TV. 

In rare cases, physical remote damage may even transmit errant signals causing TV disruption unrelated to buttons pressed on the damaged unit.

If your Samsung smart remote control is blinking red and not connecting properly with the TV despite troubleshooting other causes, it likely has physical damage necessitating repair or replacement:

  1. Thoroughly inspect your malfunctioning remote for any visible cracks, dents, missing plastic, or external wear that may indicate internal damage. 
  2. If external flaws are present, discontinue remote use immediately to avoid potentially transmitting errant signals to TV or for safety reasons.
  3. Contact Samsung support with remote model details to inquire whether warranted repair/replacement may be available. 
  4. If unrepairable, you should properly dispose of the damaged remote and purchase an exact replacement from Samsung if the remote controls are still actively manufactured. Otherwise, consider a 3rd party substitute compatible with your TV model.
  5. When first using a replacement remote, re-pair it to the TV by initiating Bluetooth sync. Consult your user manual for appropriate pairing procedures specific to your device.

7. Bug or Malware Issues 

Remotes and TVs work in tandem by maintaining a two-way communication link and sharing data and commands.

A bug disrupting signals sent between the TV and remote can cause your remote to blink red since those links rely on properly functioning, bi-directional software on both ends. 

Separately but similarly, malware or corrupt data getting into a Samsung TV OS can also trigger connection hiccups with the remote, which can cause it to blink red light.

When core television software gets infected or corrupted, it contributes to a cascade of operational defects including lost pairing ability or signal interpretation with the handset controller. 

By factory resetting an affected television to flush out unstable software and reinstalling fresh data, you can successfully restore device connectivity.

If your Samsung smart remote starts blinking red unexpectedly and you have ruled out hardware faults, try software-based troubleshooting:

  1. Power cycle remote by removing batteries for 60 seconds to force internal reset. 
  2. Unplug the TV for 2 minutes then reconnect power (i.e., plug your TV back into its wall outlet) to reboot the entire television using factory onboard software. 
  3. If the remote continues blinking red, perform a master factory reset on the TV to wipe any corrupt data and reinstall the operating system and apps. Make sure to backup settings first. You can factory reset it by holding the Return and Multi-View buttons. Wait for the red light to flash once before releasing the buttons. If done correctly, your remote will immediately try to pair with your TV.
  4. Repair the remote to freshly reset TV per on-screen setup instructions. Once you are done, the blinking red behavior should discontinue with software stability achieved. 

8. Use SmartThings App

If you have tried all troubleshooting suggestions for a Samsung smart remote that blinks red yet cannot resolve the issue, consider downloading the SmartThings app as a replacement remote control.

It provides an easy software-based solution while awaiting hardware repair or replacement.

The free SmartThings app allows Android and iOS users to use their smartphone or tablet as a fully functional remote for compatible Samsung televisions.
