Your Harman JBL CINEMA SB400 is not producing sound with the TV due to possible connection or pairing issues. Based on the context:

1. TV Connection Issues: The soundbar may not be properly connected to the TV, or the TV settings may not be configured to output audio through the soundbar. Resetting the TV to factory settings restored TV speaker sound but caused issues when reconnecting the SB400.

2. Bluetooth Pairing Issues: The SB400 was able to stream audio from an Android phone, indicating that Bluetooth is functioning. However, if the soundbar and subwoofer are not paired correctly, the subwoofer may not work. Ensure both units are within the 50-foot wireless range and press the Wireless Pairing buttons on both within 30 seconds to sync them.

3. HDMI or Input Detection Problems: If the soundbar is connected via HDMI, ensure the correct input is selected. The OSD may display messages if the HDMI connection is not detected.

4. Remote or Volume Settings: Check if the soundbar is muted or if the volume is too low. Follow the manual instructions to sync the TV remote with the soundbar.

Try rechecking connections, pairing the units, and ensuring the correct input is selected. If the problem persists, a hardware issue may be present.
