The led on the soundbar switches from red to green/white when turned on, you can see the led on the woofer blink. Make sure the soundbar is plugged into the ARC HDMI port and your rear speakers have the ac and signal wires attached. Also check your soundbar settings on your TV.
Sorry, there was a problem. Please try again later.Hello there! Thank you for sharing your experience with us. We understand that your new LG S70TR Soundbar is giving a quick beep when you press the power button and not turning on. Your feedback is important, and we'd like to assist you further. A quick beep followed by no action often indicates a power-related issue or a need for a simple reset to re-establish proper function. Please try the following troubleshooting step: Power Cycle/Soft Reset: Unplug the power cord from the soundbar. Wait for at least 30 seconds to a minute. Plug the power cord back into the soundbar. Try pressing the power button again. If this does not resolve the issue, it could be related to the initial connection to the wireless subwoofer and rear speakers, or a need for a factory reset.
