Samsung TV & Audio HW-S800B Ultra Slim 3.0 Channel 360 Watt Soundbar with Dolby Atmos and Bluetooth CEC CONFLICT Error Fix: CEC/Anynet+ Causing Unwanted Behavior

Error code CEC CONFLICT on the Samsung TV & Audio HW-S800B Ultra Slim 3.0 Channel 360 Watt Soundbar with Dolby Atmos and Bluetooth means: CEC/Anynet+ Causing Unwanted Behavior. Soundbar turns on/off unexpectedly, switches inputs randomly, or volume changes on its own. CEC (Consumer Electronics Control) allows devices to control each other over HDMI, but conflicts arise with multiple CEC devices. Common symptoms: soundbar powers on when another HDMI device activates, volume changes when switching TV inputs, soundbar switches to wrong input. Fixes: (1) limit CEC-enabled devices to TV + soundbar only — disable CEC on Blu-ray players, game consoles, etc., (2) toggle Anynet+ off then on again on the TV, (3) use a dedicated HDMI port for the soundbar (the ARC port), (4) if persistent, disable Anynet+ entirely and use optical connection as alternative (loses CEC convenience features like TV remote volume control).

The most successful fix is "Disable Anynet+ on TV and Use Optical Audio Connection" (medium difficulty, ~30 minutes). Estimated DIY cost: $0-$10. HomeMD has 2 community-ranked fixes for this error.
