Question:  

How to resolve issues caused by the automatic powering on/off of my Samsung TV through the Anynet+ feature?

Answer:

Usually when an external device connected to the TV is turned on you will be turning on the TV and switching it to that source.

For example: When you turn on your Blu-ray player you will also usually turn on the TV and switch the TV to that source to watch a movie.

Because of this Samsung devices using the Anynet+ feature will automatically turn on the TV when they are turned on and turn off when the TV is turned off. Usually this saves time and is helpful, although there are some circumstances where this can cause a usage issue and be frustrating.

For example: You want to listen to a CD on your Samsung home theater. When you turn on the home theater the TV turns on. When you turn off the TV the home theater also turns off. So you turn the home theater back on and the TV also comes on, so you turn the TV off and the home theater also turns off. If you do not know why this is happening it can be very frustrating.

To resolve an issue like this you have two options.

1. Turn off the "Auto Turn Off" function of Anynet+.
2. Disable the Anynet+ feature altogether.

Auto Turn Off Function (Menu > System > Anynet+ > Auto Turn Off: No)

Disabling this function of Anynet+ will stop the external devices from powering off when the TV is powered off but other Anynet+ functions will still be accessible. In the example above the TV would still turn on when the home theater was turned on but when the TV was powered back off the home theater would remain on.

Anynet+ Feature (Menu > System > Anynet+ > Anynet+ (HDMI-CEC): Off)

Turning off the Anynet+ feature will help you avoid situations, like the one in the example above, altogether, although you will not be able to use the Anynet+ function to control your external device with the TV remote.

Anynet+: A feature on Samsung devices that allows controlling multiple devices with a single remote control.
