If your Polk sound bar keeps turning off randomly, we have a solution for you!
The issue could be coming from problems with the power supply, either on the power outlet’s side or your soundbar’s side.
In this post, we will run through a complete troubleshooting process to identify and resolve the problem with your Polk soundbar.
To fix your Polk soundbar’s sudden shutdowns, first, make sure that it hasn’t restarted due to an update. If that’s not the case, you should try using a different wall outlet and eventually using a new power adapter.
Keep in mind that if your remote is glitching out, it could be sending false inputs to your soundbar, hence turning it OFF.
We’ll discuss everything so let’s start with the most frequently reported causes for such an issue.
When troubleshooting your soundbar, you must take several factors into consideration.
First of all, it is good to diagnose the power supply and determine if sufficient voltage is reaching your device.
Once you’ve done this, you can move on to troubleshooting the soundbar itself.
Before everything else, have a look at what caused the problem for other people:
1. Problem with a Power Source
A malfunction with your soundbar’s power outlet or insufficient voltage reaching your device could cause the device to shut down at random.
2. Remote Issue
If your remote is running out of batteries, it could cause some random inputs on the soundbar, including changing the power state.
3. Power Adapter Problem
An issue that could be on your soundbar’s end is the power adapter. You cannot exclude this possibility until you replace it.
4. Wireless Problem
In case your soundbar is connected via WiFi or Bluetooth, this could cause the device to turn off in case it got disconnected.
5. Hardware Problem
Lastly, a potential hardware issue with your soundbar could also be causing it to turn OFF.
Knowing what could be causing the problem, you’re now ready to proceed with the troubleshooting guide so let’s jump right in!
After reviewing what could have gone wrong with your soundbar, it is time to identify and solve the issue.
The very first thing to check is whether your local area is going through a power outage.
Any fluctuations in the power delivered can cause your devices to turn OFF or restart randomly.
In case there was no power outage, proceed with the solutions below:
We suggest power resetting your soundbar to resolve the problem.
If that issue is occurring due to a bug or glitch in your soundbar’ software, a power cycle would be effective since it would restart ALL services.
Here is how to power reset your soundbar:
- Disconnect the power adapter of your soundbar from the outlet.
- Wait for 5 minutes until your soundbar discharges completely.
- Re-attach the power adapter into the power source.
Turn on your soundbar and use it for several minutes to determine if it would still shut down.
There could be a problem with your soundbar’s power source.
This is why we suggest plugging the soundbar into a different electrical outlet to test if that will help.
Here is how to plug your Polk soundbar to a different source in easy-to-follow steps:
- Disconnect the power adapter of your soundbar and the power brick.
- Locate a new power source to plug your soundbar in.
- Position the device and reconnect the power components as they were before.
- Turn on your device and test.
Using a new power source should be capable of resolving the problem with your soundbar.
If your device is still shutting down, let’s inspect the power components of your device.
The power supply of your device has two separate components.
That’s the power adapter, that connects to the power brick, and then the power brick that connects with the soundbar.
We suggest getting a new power supply for your soundbar to resolve the problem. You’re looking at a 15V AC/DC adapter for Polk audio signal replacement.
Once you’ve acquired the correct power components, connect the power adapter into the brick and the power source, and then connect the power brick to your soundbar.
If your Polk soundbar has lost connection to its receiver, it will most likely shut down after a while of not being used.
In that regard, based on the connection you’re using for your soundbar, you should check if everything is okay.
Plug the first end of your soundbar’s digital optical cable on the back of your receiver then onto the soundbar. Wait for the source to be recognized on your receiver.
On your receiver, open the Bluetooth settings and make sure that your soundbar is showing up.
Locate the Bluetooth connection in your receiver’s options and initiate a connection with the soundbar. Wait.
With the instructions above, you should be able to get your Polk soundbar connected to a receiver relatively quickly.
When connected, observe whether it will disconnect and then shut down or it will shut down without disconnecting first.
Your Polk soundbar may have the auto-shutoff feature enabled.
This setting will actively cause the soundbar to shut down after a certain time. You can configure it from the device’s settings.
Note: It is recommended to have it disabled as long as you want your soundbar working all of the time.
Here is how to disable the auto-shutoff feature on your Polk soundbar:
- Make sure that your soundbar is working currently (not shut down).
- Locate the Power and Volume Down button on your Polk device.
- Press and hold these two buttons for 10 seconds.
Important: You have to press the following buttons on the soundbar itself and not on your Polk remote.
In case the auto shut-off feature was enabled, you can consider the issue solved.
However, if the soundbar keeps shutting down or the feature was disabled in the first place, proceed with the next solution.
If nothing worked for you so far, we suggest factory resetting your soundbar.
This will erase all system configurations and settings, which will hopefully solve the problem.
To reset your soundbar, press and hold the Microphone Mute and the Volume Down button for 10 seconds.
This will cause the device to restart and then all settings will be erased.
Once reset, connect your soundbar to a different device than before and check whether it will shut down or not.
In case it does, you might be facing a hardware issue and you should check if your warranty is still intact.
