Samsung Smart TV won't recognize Chromecast

Asked about this on the Samsung forums but no answer.

Bought a used Samsung Smart TV (Series 5S, UN40EH5300) and the seller threw in their Chromecast device for cheap.  Brought the setup home and now no matter which HDMI port I plug the Chromecast into, the TV keeps telling me there's "no cable connected" despite the seller having literally been showing me how the Chromecast worked when I showed up to get the TV.  The source menu lists the Chromecast under HDMI-CEC, but despite refreshing the source menu, switching ports, turning the TV on/off, and toggling through every one of the TV's menus it won't connect to the Chromecast.  I know for a fact that the Chromecast is working, as the Google Home app recognizes the device as "[seller]'s Chromecast," but the TV isn't showing me the code.

Hello, Welcome to the Chromecast Help Forum

Try each of the following before moving on to the next:
  • Are you using the Google Home app  that replaced the Chromecast app?
  • Are your Apple devices on current Minimum system requirement?
  • Turn on Bluetooth:

    1. On the home screen, tap Settings > Bluetooth.
    2. Make sure the slider is On (toggled to the right and green).
    3. Close out of Settings and return to the Google Home app .
  • Reboot your router
  • Make sure you power the Chromecast device with the provided power supply into an open electrical outlet, not using a USB input on your TV or other device.
  • Check your Apple Wifi settings
  • Your Apple device, Chromecast device and Wi-Fi Router should be within ~15 feet (4 meters) of each other. 
  • Reboot Google Home app on your Apple device > tap on Devices  > tap the Cog Wheel > tap on the three stacked dots in the top right corner > tap Reboot
  • See original post by Google employee about other settings.
  • Make sure your wifi router, iOS device and Chromecast are on the SAME 2.4 Ghz network. Not 5 GHz or Auto setting required for Chromecast (1st Gen).
  • If no resolve, contact Google support
