Samsung TV & Audio HW-B650 3.0 Channel 330 Watt Soundbar with DTS Virtual:X and Bluetooth HDMI Error Fix: HDMI Input Mode — No Signal

Error code HDMI on the Samsung TV & Audio HW-B650 3.0 Channel 330 Watt Soundbar with DTS Virtual:X and Bluetooth means: HDMI Input Mode — No Signal. Display shows "HDMI" indicating the HDMI input (non-ARC) is selected. The soundbar is expecting a direct HDMI input from a source device (Blu-ray player, game console) connected to the soundbar's HDMI IN port, with the soundbar's HDMI OUT (ARC) connected to the TV. If "No Signal" or no audio/video: verify cables are in correct ports (source → soundbar HDMI IN, soundbar HDMI OUT → TV ARC port). Check source device is powered on and outputting signal. Try a different HDMI cable. Enable HDMI passthrough in soundbar settings if available.
