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:

  1. Open the Bose Music app on your mobile device.
  2. Tap on the “Settings” cogwheel icon in the corner.
  3. Press on the “My Bose” icon in the upper-left end.
  4. Tap on Bose soundbar 900 to configure the options.
  5. Under the “Power” section, press on “Power Sync.”
  6. Activate the “Enable Power Sync” slider at the top.
  7. 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:

  1. Press the “Home” button on the TV’s remote control.
  2. Navigate to “Settings” and enter the “Audio” section.
  3. Next, find and highlight “Output” or “Default Output.”
  4. Specify your device’s existing wired cable connection.
  5. 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 TVAnynet+ (or only “Anynet”)
LG TVSimpLink
Philips TVEasyLink
Panasonic TVVIERA Link
Toshiba TVREGZA-LINK or CE-Link
Hisense TVAnyview 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.
