LG Subwoofer Blinking Green? Try These Fixes

LG Subwoofer Blinking Green

When your Subwoofer is blinking green, you might be confused as to what to do. There are a few problem-solving techniques you might want to try.

Why is LG Subwoofer Blinking Green?

There are several reasons a subwoofer might be blinking. Sometimes it’s a connection issue, and sometimes, it’s another issue that you can take care of on your own.

When it’s blinking, it’s usually because there is something that is keeping it from connecting and working properly. There are a few things you can do in order to try to get it fixed and working the way it should.

1. Power Issue

This is probably one of the most common issues that you might have gone through. When you don’t have the power to run the subwoofer, it simply won’t work right.

This can happen for a few different reasons. It might be that you just don’t have the power to run it, or something isn’t hooked up the way it should be in regard to the power supply. It greatly depends on how you run it and how it’s all put together.

Fix: Make Sure It’s Plugged in Properly

This is the most common issue you will find. It’s also the easiest to fix. When something isn’t connected properly, it will not give you enough power to run the subwoofer.

You should check your hookups and make sure it’s in the socket correctly and plugged into the back of the subwoofer like it’s supposed to be. You can also check the plug and switch that out if it’s still not working properly.

It’s possible the outlet is damaged or not connecting as it should be. This is more common in older homes but can happen anywhere.

Sometimes things just break in a home, and you won’t know unless something plugged in isn’t working, or there is another issue with the electrical.

Fix 2: Make Sure the Power Cord is Working Properly

You should also check your power cord. It’s possible that it’s been kinked while in storage, or it has other problems with it.

Take a look at your cord and make sure the coating is still in place and there are no frays or other issues that could cause it not to connect properly.

If you find there is a hole or other issue with the cord, you should replace it (view on Amazon) right away and get something that will connect better. This could not only cause an issue with the subwoofer but also could start a fire.

Neither are issues you want to deal with. You can get a replacement from the manufacturer, or you can probably find something at the local tech store. If they don’t have one, you can probably order it from them.

2. You’re Using an Extension

An extension can really cause a lot of issues if it’s not done correctly. If you are using one and haven’t used it before, you might want not to use it and look at hooking directly to the wall.

This can cause problems because it’s not meant to be used all the time, but if you are using something with a surge protector on it, you might want to try only plugging in the subwoofer when you are using it the subwoofer to keep it safer.

If that isn’t an option, you might need to problem-solve the extension to make sure it’s not causing the issue and not letting power get to your subwoofer. Look at it and see if there are any signs of damage to it.

If there is, then it’s possible that is keeping the power from going to the subwoofer as it should. If there isn’t anything that is visible, but you have a second one, you might want to switch it out and see if that is working better for you.

If there is any damage, seen or not, then you won’t be able to use the extension at all. You can look at getting another one that will work better. This might solve your issue if the extension what the reason for the issue in the first place.

Fix: Use A Wall Socket

When you are running your subwoofer through an extension, it can cause issues if it’s not working correctly or if it’s turned off. You can look at your extension and see if there is an issue with it.

If there isn’t, then you can unplug it and plug it into the wall socket. This way, there isn’t another thing in the way of the power getting to your subwoofer. If this doesn’t fix the issue, you will have to keep looking for what is causing your problem.

There may not be an issue with your power supply if these few tricks don’t work. You might also need to look at your electrical in the home. You can hire someone to come in and look at your electrical outlets and see if there are any issues.

If there has been any kind of water damage, it can make your wires wet and not connect as they should. This can also be a larger problem with your electrical. You don’t want to let something like this go. If you are having this issue with more than just your subwoofer.

That will clearly be a sign there are bigger issues that you need to look into fixing. Try another outlet and see if it powers the subwoofer better.

It’s possible when there is damage to the wall socket and electrical system for power to still go through the system, but it is not enough to actually power your items. This way you will know if a bigger issue is making it hard to get power to your items.

3. The Subwoofer Isn’t Paired

It’s possible the Subwoofer isn’t paired to the device you want to listen to. This can happen if you have something else paired to your device or if it’s not set up correctly.

If you are using Bluetooth, you will find there can be issues with things not pairing and staying paired sometimes. If you have multiple devices that you are connecting your subwoofer to, you might want to check it out.

They could be connecting to that device and not the one you want it to connect to. This can make the sound from the device you aren’t using go through the subwoofer. If this is happening, you can forget the subwoofer on the device you don’t want to use.

This way, you will be able to get the subwoofer to connect to the right device, hopefully. You can check your device and see if it’s paired or if something else is saying it’s paired.

Some items will pair more than one thing, but there could be sound issues that cause problems. If the sound isn’t right, you might want to repair everything and see if that helps it to sound better.

Fix: Try and Pair Your Soundbar to Subwoofer Again

The easiest thing to do is to try and pair your subwoofer again. This might clear anything that is going on that is making it not pair correctly. If this isn’t the issue, then you can unpair everything and start with the subwoofer and see if it picks it up.

Then you can backtrack to the other items you want to pair, such as the soundbar, and see if it works better then. Sometimes the device will get confused when it’s trying to connect and not working properly.

You might also need to look at what is paired with the device. Sometimes there are things you aren’t thinking about that are paired to the device you want to play the sound from. This simple conflict could cause you not to be able to pair the right way.

Take a look at what you have paired and make sure this isn’t happening. This takes care of all of that and should help you to pair successfully.

Fix 2: Keep the Subwoofer and Soundbar Close

If you are having trouble pairing the device, then you might have your items too far away. You can keep the subwoofer and soundbar close to make sure they can connect as they should.

Something as simple as a wall can cause your connection not to work right. If you can get everything in the same room, then you will be more likely to get it connected as it should. You might even have issues if you are on a different floor.

This is because they can be problems with the electrical cords in the walls and interference from the subfloor. This is especially true if you are in a concrete building. Signal just can’t get around the whole building like you might want it to.

This is why it’s important to get everything in the same room if possible. If you are still noticing problems, then you can try to pair them again.

This way, you can see if it is having an issue connecting to the device even when it’s close by. If they are successfully connecting, then there is a different issue that you need to look at.

4. There’s A Bug

Sometimes there’s just a bug that’s causing issues. It might be something that is in the device you’re trying to connect to or the subwoofer itself. There are a few things you can try in order to get it working again.

You should also check the software and make sure it’s up to date. This can help you to clear any software bugs that might be happening. If you are unsure about the software being updated, you can connect it to the internet and check for any updates.

New Subwoofers operate on complex hardware and sometimes software that needs to be kept up to date. Checking every so often is a good way to keep your subwoofer working the way it’s supposed to.

You may also want to check your device software and make sure it’s up to date. If your phone is not operating on the newest software, it can cause issues with connecting and using the subwoofer.

Check your device by connecting to the internet and looking at your operating system software. It will let you know if there is a new version that you need to update. Once that is done, you can try connecting again and see if that is what caused your issue.

Fix: Unplug Subwoofer and Sound Bar for 60 Seconds, Then Plug Back In

You can try unplugging the sound bar and then plug it back in. this will help clear any issues that might be causing the subwoofer not to connect and work properly. You can leave it unplugged for a bit longer if you think this is the issue.

Sometimes just unplugging something can take the bugs away and make it work as it should. You can wait for 60 seconds or a couple of minutes to make sure it’s really getting that nice reset.

You could also leave it for a few hours if you want, so it completely charges down and is more as if you had purchased it brand new again. If this doesn’t work, you can call the manufacturer or look online and see what they say to try next.

They will normally have a section that can help troubleshoot what could be going wrong. They also will have a way for you to contact them if there is nothing that is working on your end. Keep this in mind if you are still having trouble after trying everything.

Fix 2: Hard Reset Subwoofer and Soundbar

This is a lot like hard resetting a phone. There should be a reset button on the subwoofer that will allow you to reset the device and get it back to the settings it had out of the box. This means anything that remembers the device might not connect.

It’s a good idea to forget the subwoofer from the device before you start to pair it. This way, you will have a clean connection when you try to connect it again. You can also unplug everything and let it sit for a bit to attempt to clear the bug.

This can help you because the subwoofer has time to reset without causing you to lose any of your saved connections.

This can also get the bugs out of the connection because it’s not trying to connect to your device or anything constantly. It’s just sitting and waiting for you to connect it again.

You can also try to leave it paired, but if the bug is on the end of the device, it probably won’t help the connection issues.

Fix 3: Reset Both Devices

If you are still having issues with the device connecting to the subwoofer or if this isn’t fixing the blinking light, you can try resetting both the device you are attempting to connect to and the subwoofer.

This will give you a fresh start with the connection on both sides. You might want to back up your device if you have things you don’t want to lose, but it should eliminate any of the bugs that could cause you an issue.

If this doesn’t work right away, you can play around with the connection and use a different device to see if that is going to help.

This will also be able to troubleshoot if this is a connection issue that is going on with the device or with the subwoofer. Then you can work on the one that is causing the issues and move forward in your troubleshooting.

Fix 4: Contact LG

If nothing is working and you can’t get connected, or the subwoofer just won’t work, then you can contact LG. They will have techs that can walk you through what you can do to figure out what is going on with your subwoofer.

They also may be able to help you if the subwoofer is just not going to work. They can get you the information to use the warranty and where you can take it. Sometimes you can take it back where you got it from and get a new one back right away.

If not, they can help you send it to them so they can look at the hardware and see if there is an issue that they can fix. Sometimes it’s just a faulty part or something with the software that is making it not connect properly.

Getting a blinking green light on your subwoofer can be confusing and can make you wonder what is going on with your subwoofer, but there are so many things that can be done to get it working right again.

Take a minute and really problem-solve the issue so you can be sure you are getting it taken care of in the right way. If you are worried about anything, then you can call LG, and they can help you get things working again.
