Is your TCL soundbar not turning on, randomly powering off, or showing no signs of life at all? Don’t worry—this guide walks you through the most common power-related issues and how to fix them step-by-step.

🔌 Issue 1: Soundbar Won’t Turn On

✅ Step 1: Check the Power Source

Make sure the soundbar is plugged into a working wall outlet (not a power strip or surge protector, if possible).

Test the outlet with another device (like a lamp or phone charger) to confirm it’s delivering power.

✅ Step 2: Inspect the Power Cord

Check the power cord for visible damage—cuts, fraying, or bent connectors.

Ensure the connection is secure at both ends (wall and soundbar).

If your soundbar uses an external power adapter or brick, make sure it’s firmly connected to both the power outlet and the soundbar.

🎛️ Step 3: Try the Power Button on the Soundbar

Press the power button directly on the soundbar (not just the remote).

Sometimes the remote battery may be dead, or the signal isn’t reaching the IR sensor.

👉 If the soundbar powers on with the button but not the remote, the remote may need new batteries or replacement.

🔁 Step 4: Power Cycle the Soundbar

Sometimes a quick reset clears up a frozen or unresponsive unit.

Unplug the soundbar from power.

Wait at least 30 seconds.

Plug it back in and press the power button.

🔋 Issue 2: Soundbar Turns On, Then Immediately Turns Off

This could be caused by auto power settings or connection issues.

✅ Check for These:

If the soundbar is set to Auto Standby, it may turn off automatically after a few minutes of inactivity. Try disabling this setting (see user manual).

Ensure an active audio signal is being sent to the soundbar (from TV, phone, or other source).

If you’re using Bluetooth, the soundbar may turn off if it loses the connection.

🔄 Issue 3: Soundbar Won’t Stay On / Powers Off Randomly

If your soundbar keeps shutting off on its own:

Make sure CEC (T-Link) is enabled if using HDMI ARC—this allows the TV to manage soundbar power.

If the soundbar is connected to a TV’s USB port for power, try plugging it into a wall outlet instead—USB ports often cut power when the TV turns off.

Check if a firmware update is available for your soundbar (via USB, if supported)—some older firmware versions may have auto power-off bugs.

💡 Indicators to Watch For

No LED or display lights = power issue

Flashing lights = pairing, connection, or error state

Solid light, then off = potential auto shutoff or signal issue

🧪 Still Not Turning On?

If none of the above worked:

Try a different power cord or adapter (if your model allows).

Make sure no fuses or surge protectors are tripped.
