Bluetooth / smart remote won't pair

Smart remotes use Bluetooth/RF for most keys and IR only for a few (often power). Fix batteries first, then reset and re-pair close to the TV sensor.

Soundbar or receiver has no audio over HDMI ARC/eARC

Almost always a settings or port problem: CEC off, ARC/eARC not enabled, soundbar on a non-ARC port, or the TV's audio format set to something the bar can't decode. Work through settings before suspecting hardware.

TV won't turn on (standby light only, or blinking)

Separate power-delivery problems (outlet, surge strip, remote) from internal failures. A steady standby light with no response is often remote or button related; a blinking light after a clean power cycle on a good outlet is a hardware fault, usually the power supply board.
