Reset LG S70TY Soundbar, Step-by-Step Instructions
- Ensure the soundbar is turned ON and connected to a stable power source.
- Locate the Volume Down (−) button on the soundbar and the 0 (zero) button on the remote.
- Press and hold both buttons simultaneously for at least 5 seconds.
- Wait for the display to show “E2P CLR” and let the soundbar power off automatically.
- After shutdown, turn the soundbar back on to confirm reset, then re-pair all devices.
- After the soundbar powers off automatically post-reset, wait at least 10 seconds before turning it back on manually. This ensures that the memory clearance completes successfully.
- Restore connections by re-pairing Bluetooth devices, reconnecting HDMI ARC or optical cables, and ensuring your TV audio output is set to external speakers or HDMI ARC.
- If you use a subwoofer, press and hold the pairing button on the subwoofer for 5–10 seconds until the LED blinks. The soundbar should automatically detect and connect.
- Reconfigure custom settings such as sound modes, EQ levels, and connection preferences using the remote or LG ThinQ app for optimal sound performance.
- Confirm that all features—Bluetooth, subwoofer, HDMI ARC, and audio modes—are functioning properly after the reset. Perform a test play session from your TV or mobile device.
Troubleshooting
| Issue | Solution |
|---|---|
| No response after reset attempt | Ensure the LG S70TY soundbar is powered on. Use fresh batteries in the LG remote if performing a remote-based reset. Try alternate button combinations if the standard reset method fails. |
| Subwoofer will not pair | Power cycle both the subwoofer and the soundbar. Hold the subwoofer pairing button for 5–10 seconds until the indicator blinks. Keep both devices close and retry pairing. |
| No sound after resetting | Confirm the TV audio output is set to HDMI ARC or optical out. Verify that CEC (Simplink) is enabled when using ARC. Reconnect and secure all cables properly. |
| Bluetooth pairing fails | Clear previously paired Bluetooth devices from the soundbar memory. Enable pairing mode again by holding the Bluetooth button. Forget the old connection on your device and re-pair. |
| Reset did not resolve audio issues | Update the soundbar firmware from LG’s official website. Some issues may persist until patches are applied. Minimize interference from nearby wireless networks or RF sources. |
Advanced Tips
- After reset, reselect your preferred sound modes like Standard, Bass Blast, or Cinema for a personalized experience.
- To resolve ARC or control issues, enable or disable CEC (Simplink) in your TV settings to ensure proper volume and power sync.
- Position the subwoofer at least a few feet from Wi-Fi routers or metal objects to avoid signal interference and disconnection.
- Use the LG ThinQ mobile app for easier customization and firmware updates post reset.
- Perform occasional soft resets (unplug for 30–60 seconds) to maintain long-term stability if settings begin acting up.
