  If Anynet+ isn't functioning on your Samsung TV, there are several things to check: * First, verify that the connected device is actually an Anynet+ compatible device, as the system only supports these. * Ensure the power cord of the Anynet+ device is securely connected. * Check all Video, Audio, and HDMI cable connections to the Anynet+ device. * Confirm that Anynet+ (HDMI-CEC) is enabled in your Samsung TV's System menu. * Verify that the remote control you're using is Anynet+ compatible. * Be aware that Anynet+ may not operate during the initial setup phase. * If you've reconnected the HDMI cable, perform a device search again or power cycle your TV. * Finally, ensure the Anynet+ function is enabled on the Anynet+ device itself.
