Bose Soundbar 900 Flashing White Light – Quick Solutions!

Reminder: Have you waited at least 5 minutes to check if the white flashing light will disappear?

1. Soft-Reset Your Bose Soundbar

The first step against the persistent blinking white light on your Bose soundbar 900 is to perform a soft reset, also known as a “power cycle”.

This is essential since the primary indication of the white light is that the soundbar is rebooting, hence, the speaker might be stuck in a boot loop.

To soft reset your Bose 900 soundbar, follow the instructions:

1. First, power off your Bose soundbar 900.
2. Unplug the power cable from the socket.
3. Also, disconnect the connected speakers.
4. Wait for at least 60 seconds for discharge.
5. Reconnect your Bose soundbar to power.

It’s normal for the white light to blink immediately after you turn on your Bose 900 soundbar, as this means that the operating system is loading.

However, if the white light remains blinking for more than 2 minutes, something else is causing the issue.

2. Reconnect to Bluetooth or Wi-Fi

If Bose smart soundbar 900 white light flashing remains for a prolonged period, the unit might be attempting and probably failing to connect via Bluetooth or Wi-Fi.

This happens when your internet/Wi-Fi is not accessible or when something is preventing the Bluetooth connection.

So, the best thing you can do next is reconnect your Bose soundbar 900 to Wi-Fi or Bluetooth!

How to Connect Bose 900 Soundbar to Wi-Fi?

1. First, you must put the Bose soundbar in “Setup Mode”.
2. As per your remote, use a different button combination:

3. After 5 seconds of holding, the soundbar will flash amber.
4. Connect your phone to the temporary soundbar’s Wi-Fi.
5. Then you must open the Bose Music app on your phone.
6. Follow the steps to pair your Bose with the correct Wi-Fi.

How to Connect Bose 900 Soundbar to Bluetooth?

1. Hold the “Bluetooth” button on the soundbar’s remote.
2. Wait for 30–45 seconds for the feature to be activated.
3. Open the Bluetooth menu on the Android or iOS phone.
4. Select the Bose soundbar’s Bluetooth profile to connect.

If you’re attempting to connect to the Wi-Fi, ensure that your network is accessible by using your phone and then connect the soundbar.

In contrast, if you’re trying to pair the Bose soundbar via Bluetooth, ensure that your source is close to your soundbar and that there is no interference.

Note: When the soundbar connects to Wi-Fi or Bluetooth, the white blinking light will disappear!

3. Unpair Bose from Voice Assistant

Well, if you’ve checked the Bose soundbar 900 white light indications, you might have noticed that most of them are related to a connected voice assistant.

Sometimes, a bug causes the white light to slide, blink, or glow, especially due to a fault with the connected voice assistant.

Hence, if you have paired your Bose soundbar with Alexa or Google Assistant, we recommend temporarily disconnecting it, to check if this will solve your problem. 

How to Unpair Bose from Alexa?

1. First, open the Alexa app on your phone.
2. Then, go to “Devices” → “Echo & Alexa.”
3. Choose your Bose 900 and “Deregister.”
4. Head to “Account” → “Other Programs.”
5. Proceed by selecting “Login with Amazon”.
6. Lastly, “Remove” all instances of your Bose.

How to Unpair Bose from Google?

1. Open the Bose Music app on your phone.
2. Then, go to “Settings” → “Voice Assistant.”
3. Then, select “Google Assistant” on the top.
4. Finally, choose “Remove” to disconnect it.

When you’re ready, and your Bose soundbar 900 is not connected to a voice assistant, check if the white blinking light is still there.

If yes, don’t rush into pairing your assistant back, and keep reading the solutions ahead, until you identify the cause.

4. Check the Remote for False Signal

If your Bose soundbar 900 light bar is blinking on the right or the left side only, this means that the device is currently receiving volume control commands.

If you’re not sending these volume commands, it’s possible that your remote is glitching out, and constantly sending false signals.

One quick way to find out whether this is the culprit is to remove the remote’s batteries for 60 seconds and observe whether the white light keeps blinking.

If not, then your remote control is causing all this fuss, hence check for stuck volume buttons, and ensure there are no defects.

Note: If you put the batteries back into your remote and the Bose 900 soundbar starts blinking in white, it’s definitely a false signal, so the remote might be defective.
