Soundbar or home theatre system does not turn on

If your soundbar or home theatre system isn’t powering up, try these steps to resolve the issue.

Step 1: Check the power cord connection

• Ensure the power cord is securely connected to an AC outlet or AC adaptor.
• If the power cord is loose or disconnected, the device may suddenly turn off or not power on at all.

Step 2: Test the power strip (if in use)

• If you’re using a power strip (extension cord), unplug the device and connect it directly to an AC outlet.
  • If the device powers on when connected directly, your power strip’s protection circuit may have tripped due to issues like lightning or overvoltage. Replace the power strip and try again.

Step 3: Verify the AC outlet

• Plug another device into the same AC outlet to see if it powers on.
  • If other devices don’t work with the outlet, the outlet may be faulty.
  • If other devices work, proceed to the next step.

Step 4: Wait for the soundbar or home theatre system to restart

• After connecting the power cord to a power strip or AC outlet, wait a few moments for the device to restart. Some devices take time to power on after being reset.

Step 5: Perform a power reset

• Unplug the device from the AC outlet for at least 20 minutes. Then, plug it back in and try to power it on.

Notes:

• The device’s protection circuit may activate if it detects abnormal voltage (e.g., from lightning strikes or overvoltage). Waiting while the power cord is unplugged may resolve this.
• To protect your device, follow the power supply voltage guidelines and unplug during expected lightning storms.

Step 6: Reset to Factory Settings

• Reset the soundbar or home theatre system by following the Help Guide or Operating Manual instructions. Alternatively, you can consult this How to reset the soundbar or home theatre system article
  Note: After resetting, wait a few moments for the device to restart. Some devices take time to power on after being reset.

Note: A full reset will restore factory settings.

Step 7: Seek Professional Service

• If these steps don’t resolve the issue, a professional repair may be required. Consult a repair service for further assistance.
