An LG TV’s remote can stop working if the batteries are low, TV’s IR Receiver is clogged or there is an issue with the remote’s circuitry.
That’s the general rule!
But often above-mentioned things will be fine, but still, you will notice your remote is not working and the red light blinking.

“Why is my newly purchased LG remote stopped working? I know it’s a dumb question. But my remote’s batteries are fine, power cycled the TV multiple times, but still no luck. I ended up seeing my remote flashing red. Any idea how to fix it?”—Sefia, India
Well, in this guide, I will break down everything about why your LG TV remote flashing red and not working and exactly what you need to do to get back it working.
Let’s dive into it…
How to Fix LG TV Remote Not Working Red Light?
Here’s the detailed step-by-step process:
Method 1: Check the remote for continuity
Before carrying out any silly actions, I advise you to perform this test as a first step. This will help you in determining whether the remote is functioning correctly.
Here’s how to test for continuity:
- Launch the camera app on your smartphone.
- Then, point the remote control towards the camera lens and push any button.
- Observe the camera screen for a flashing light coming from the end of the remote.
If you spot a flashing red light, remote has continuity and is working properly. If you do not see any flashing light, remote doesn’t have continuity.
♦ Remote has continuity
In this case, several options exist to get back the remote working again.
Here’s what you have to do:
- TV needs a power reset: Unplug it from the power outlet and wait for at least 60 seconds. Hold down the power button on the TV for about 30 seconds while it is unplugged. Reconnect the TV once you’re finished.
- TV’s IR receiver is dusty: The IR sensor receives signals from you and sends them to the TV’s motherboard for processing. But over time, it becomes clogged with dirt or dust. If this happens, the TV won’t respond to your commands. Carefully clean the sensor with a soft cloth to remove any blockages.
- Reset the remote: Sometimes sudden power shortages cause the internal components in the remote to start malfunctioning, necessitating a reset in order for it to function once again. Simply remove the batteries, press all of the buttons, hold the power button for 15 seconds, and replace the batteries.

♦ Remote doesn’t have continuity
Anyway, if the test proves the remote doesn’t have continuity, then either the remote’s batteries are damaged, or the remote’s battery contacts are dusty.
Do the following things before buying a new one:
- Clean the batteries’ contacts: Remove the batteries and look for any signs of white powder, solidified granules, or green coloration on the contacts. If present, clean them with rubbing alcohol and cotton before replacing the batteries.
- Replace the batteries: Skip this if you have recently replaced the batteries. But if not, buy a new set of batteries and then put them in the remote. You can also use batteries from another remote control.
- Buy a new remote control: Now you know your remote is faulty. Order a new one from Amazon, and you are good to go!
Method 2: DIY Repairs: LG TV Remote Not Working
If you’re someone who enjoys fixing things yourself, here’s a rewarding DIY task for you: restoring your non-functioning LG TV remote to life.
There’s a possibility that cleaning the inner parts of your remote control could revive it and save you some money.
Here’s the step-by-step process:
Step 1: Gather your tools
Before you begin, gather the necessary tools: a small Phillips or Penta screwdriver (depending on the screws), a toothbrush, isopropyl alcohol or contact cleaner, cotton swabs, a microfiber cloth or towel, and optionally, compressed air.
Step 2: Remove the batteries
Take out the batteries from the battery compartment of the remote control.
This precautionary step ensures safety and prevents any electrical accidents during the cleaning process.
Step 3: Disassemble the remote
Inspect the back or sides of the remote control for screws. Use the appropriate screwdriver to unscrew them and set them aside carefully.
In case there are no screws, you might find clips that can be gently pried open using a small flathead screwdriver.
Step 4: Clean the buttons and housing
Take out all the buttons from the remote control. Use a toothbrush to delicately scrub the button surfaces and the inside of the casing.
This will help remove any dirt, grime, or debris that could be causing unresponsiveness.
For more thorough cleaning, moisten the toothbrush with isopropyl alcohol or contact cleaner and continue scrubbing. Be cautious not to let any liquid penetrate the electronic components.
Step 5: Clean the circuit board and button contacts
Dampen a cotton swab with isopropyl alcohol or contact cleaner.
Gently clean the circuit board and the button contacts, both on the circuit board and the buttons themselves. Pay attention to any areas with visible dirt or residue.
Avoid applying excessive pressure to prevent damage to the delicate components.
Step 6: Dry and remove residue
Use a microfiber cloth or towel to gently dry the components and eliminate any remaining residue.
Ensure everything is completely dry before reassembling the remote.
Optional: If you have compressed air, use short bursts to blow out dust and particles from the remote control’s crevices and openings. This prevents loose debris from affecting the remote control’s functionality.
Step 7: Reassemble and test
Now, it’s time to put everything back together. Follow these steps:
- Place the cleaned buttons back into their respective positions on the circuit board.
- Gently press the buttons to ensure they fit securely.
- If there were screws, reinsert them into their original locations and tighten them securely.
- Insert fresh batteries into the battery compartment.
Now it’s time to test the remote control:
- Point the remote control at the device it operates (e.g., TV).
- Press various buttons on the remote control to verify that they respond and function correctly.
If all the buttons work as expected, congratulations! Your LG TV remote control is now fully functional

Q: LG remote power button Flashing
The flashing power button on an LG remote indicates that the battery is low, the remote is in pairing mode, there is interference blocking the signal, or there is a software glitch.
♦ Low Battery: The most common reason for the power button flashing is that the batteries in the remote are running low. Replace the batteries with fresh ones and see if the flashing stops.
♦ Pairing Mode: Some LG remotes have a pairing mode where the power button flashes to indicate it’s ready to pair with the TV. In this case, follow the pairing instructions in your TV’s user manual or on the LG website to complete the pairing process.
However, If the remote has been dropped or exposed to water or other damage, it may also cause the power button to flash.
If this is the case, you need to replace the remote.
