Why does my Apple TV 4K not turn on my tv after it is off for several hours?

Hello adamj4130,

If you are using your TV remote to control your Apple TV, these steps and suggestions may solve or shed some light on your issue:

"If your TV or receiver supports HDMI-CEC, Apple TV uses the HDMI connection to allow it to be controlled by your TV or receiver remote.

If some features don't work:

1. Make sure your TV or receiver offers HDMI-CEC support. For help, contact the TV manufacturer or check the manual.
2. Check that your Apple TV is connected to an HDMI port that supports HDMI-CEC. Check the TV manual to confirm which ports support HDMI-CEC.
3. Check that HDMI-CEC is turned on in the menu of your TV or receiver. Use the remote that came with your equipment. As manufacturers often have different names for HDMI-CEC, look for a setting that ends in "Link" or "Sync". Here are some examples:

• LG: SimpLink
• Philips: EasyLink
• Samsung: Anynet+
• Sharp: Aquos Link
• Sony: BRAVIA Sync"

You can find these steps along with other information that may be helpful, here: If you can't control your Apple TV with your home cinema or universal remote – Apple Support

We also recommend restarting your Apple TV and keeping it updated as those steps assure you have cleared out any minor software issues and are running the most current version.
