Bose Soundbar 900 Won’t Turn On – Solved in Easy Steps!

Tip: Follow the steps consecutively!

1. Soft Reset the Bose Soundbar

You can address issues with the Bose soundbar by performing a soft reset of the hardware.

It is a quick and efficient solution to discharge the power from your soundbar’s components and resolve underlying startup or functionality issues.

Follow these steps to soft reset the Bose soundbar 900:

Unplug the Bose soundbar from the power supply.
Hold “Power” on the Bose soundbar’s remote control.
Next, release the “Power” button after 30–35 seconds.
Reconnect the Bose soundbar unit to the power supply.
Test the functionality of the device using the Bose remote.

Note: Inspect the power adapter for physical damage while it is disconnected!

2. Inspect the A/C Cord’s Connections

A potentially loose or unsecured connection in the power cord will prevent your Bose soundbar from drawing a sufficient electrical supply.

So, the next step is to ensure all cables are properly installed and verify that the adapter is in good condition.

How to Inspect Bose Soundbar A/C Connection?

Inspect the following connections in the Bose soundbar 900’s setup:

The connection of the power adapter with the electrical outlet.
The connection of the power adapter with the soundbar’s port.
Optional: The connection between the cable and the adapter.

If you’re using a third-party power adapter, there could be an extra connection between the supplying cable and the A/C power adapter.

Notice: Replace any cables or equipment that have visible damages, such as rips, cuts, or bent connectors.

3. Alter Soundbar’s Electrical Source

There could be a fault or a power insufficiency caused by the electrical socket of your Bose soundbar 900.

If that’s the case, the audio device will not power on unless reconnected to an alternative outlet that can supply a proper amount of power supply.

How to Test the Wall Outlet?

Before relocating any of the Bose soundbar’s equipment, it is strongly advised to test the power outlet’s functionality by connecting any other electrical appliance.

Perhaps the easiest method to test the outlet is installing a smartphone and a compatible charger and checking the charging.

Important: Plug your Bose soundbar directly, without third-party outlet connectors!

4. Factory Reset Bose Soundbar 900

So, based on the services you have associated with the soundbar, the factory default restoration may require or not require removing the soundbar from the Google or Alexa account.

5. Replace Bose’s Power Equipment

If you’re still unable to turn on and use the Bose soundbar, you should connect an alternative power cord to the device.

Like most soundbars and audio devices, your Bose soundbar 900 uses a 2-prong power cable, so finding a replacement is easy every home has a few of those.

Once you have a replacement cable, disconnect the existing one and reconnect the soundbar to the power.

If possible, test the previous power adapter of the soundbar with another compatible device to determine if it is working properly.

Tip: Inspect the soundbar’s power port before installing the new adapter!

Why is the Bose Soundbar 900 Not Turning On With TV?

Turning on the Bose soundbar 900 is possible with the “Power Sync” feature, available within the mobile app.

So, if you haven’t enabled the feature yet, you must learn how to do it correctly.

Activate Bose’s “Power Sync” Feature

You can allow the Bose soundbar to turn on simultaneously with the connected TV through the “Power Sync” feature available within the Bose app.

You can also sync a particular source of the Bose soundbar 900 where an output device is connected, beside the connected TV device.

Here’s how to activate “Power Sync” through the Bose mobile app:

Open the Bose Music app on your mobile device.
Tap on the “Settings” cogwheel icon in the corner.
Press on the “My Bose” icon in the upper-left end.
Tap on Bose soundbar 900 to configure the options.
Under the “Power” section, press on “Power Sync.”
Activate the “Enable Power Sync” slider at the top.
Optional: Enable “Sync TV,” “Sync Source,” or both.

Note: The “Power Sync” requires a wired connection as it doesn’t work over Bluetooth!

Set Bose as the “Default Output Device”

An alternative to turning on the Bose in unison with the television is setting the soundbar as the default output device within the TV’s settings.

For this purpose, all you’re going to need is the TV’s remote and basic knowledge of how to find and navigate through the TV’s audio settings.

Here’s how to universally specify the default output device on any TV:

Press the “Home” button on the TV’s remote control.
Navigate to “Settings” and enter the “Audio” section.
Next, find and highlight “Output” or “Default Output.”
Specify your device’s existing wired cable connection.
Save the changes and exit the TV’s audio configuration.

Note: You will be unable to specify the soundbar as a default output over Bluetooth pairing!

Set Up and Use “HDMI-CEC” On the TV

If Bose’s “Power Sync” won’t make the soundbar turn on with the TV, you should activate and set up the “HDMI-CEC” feature within your TV’s settings.

As long as the soundbar is connected via HDMI to the TV, the “Consumer Electronics Controls” allows you to communicate with both devices using a single remote.

Most often, the “HDMI-CEC” feature can be found under the “Audio” or “Settings” tab within your TV’s settings.

However, here’s how the feature is called on most of the popular TV brands:

TV Brand:	HDMI-CEC Name:
Samsung TV	Anynet+ (or only “Anynet”)
LG TV	SimpLink
Sony BRAVIA TV	BRAVIA Sync
Philips TV	EasyLink
Panasonic TV	VIERA Link
Toshiba TV	REGZA-LINK or CE-Link
Vizio TV	CEC
Hisense TV	Anyview or HDMI-CEC

Tip: If not under the “Sound” or “Audio” menu, search for HDMI-CEC under “HDMI Settings”!

Quick Recap

If the Bose soundbar 900 won’t turn on, power cycle the device’s hardware, test the electrical outlet, and inspect the power port for obstructions.

If the issue persists, replace your soundbar’s power cord and force a system factory reset.
