Samsung TV & Audio HW-S800B Ultra Slim 3.0 Channel 360 Watt Soundbar with Dolby Atmos and Bluetooth REMOTE FAIL Error Fix: Remote Control Not Responding

Error code REMOTE FAIL on the Samsung TV & Audio HW-S800B Ultra Slim 3.0 Channel 360 Watt Soundbar with Dolby Atmos and Bluetooth means: Remote Control Not Responding. Samsung soundbar remote (IR-based) does not control the soundbar. Samsung soundbar remotes are infrared (IR) — they require line of sight to the soundbar's IR sensor (typically at the front-center of the soundbar). Check: (1) replace batteries (CR2032 or AAA depending on remote model), (2) ensure nothing blocks the IR sensor on the soundbar (no objects, tape, or labels over the sensor window), (3) test IR emission: point remote at a phone camera and press a button — you should see a flash of light through the camera (IR is normally invisible to the eye), (4) if controlling via TV remote (using HDMI-CEC), ensure Anynet+ is enabled on both TV and soundbar, (5) if remote controls other devices but not the soundbar, try factory reset.
