The television automatically changes its source.

Discover why your Samsung TV switches sources automatically and learn how to disable HDMI-CEC (Anynet+) using remote codes and firmware updates.

Your Samsung TV may automatically switch sources due to HDMI-CEC (Anynet+), which allows connected devices to control the TV. This feature can be disabled using specific remote codes, but firmware updates and external device issues may also affect functionality.

1. Why does my Samsung TV change sources automatically?

Samsung TVs and the Odyssey Ark gaming screen use Anynet+ (HDMI-CEC), a feature that lets connected HDMI devices signal the TV to switch sources when powered on. While convenient, this can cause unwanted source changes. Additionally, external devices may send incorrect signals, triggering automatic switching even when inactive.

2. How do I stop my Samsung TV from switching sources automatically?

To disable automatic source switching, follow these steps:

1. Update your TV's software: Ensure your TV's firmware is up-to-date, as some models require updates to enable or disable this feature.
2. Enter the remote code: Point your remote at the TV and input the code: Mute, 7, 2, 9, and Exit. No visual confirmation will appear, so test by powering on a connected HDMI device.
3. Repeat if necessary: If the TV still switches sources, repeat the code entry quickly. Once successful, the TV will stop switching automatically.

3. What if the first code doesn't work?

If the initial code fails, try this alternative method:

1. Ensure you're on the TV source: Confirm you're not on an HDMI input before proceeding.
2. Enter the alternative code: Point your remote at the TV and input the code: Mute, Volume Down, Channel Down, Mute. Again, no visual confirmation will appear.
3. Test the change: Power on a connected HDMI device to verify the TV no longer switches sources automatically.

-Note: Activate Mute by pressing in on the Volume rocker.

4. Additional things to check

-Check for firmware updates on connected devices, as incorrect signals from external devices can trigger automatic switching.

-Ensure your TV supports disabling Anynet+. Some models may not have this option.
