Solved! Special HDMI cable or input for Fire to control TV?

[jnojr]

My Fire Cube won't control my TV (Insignia NS-55DR620NA18) It keeps saying to press FF if the TV turned off, and on the screen is says to pres Rewind to try again. Over and over and over and over again. It recognizes the TV as an Insignia.

Has this ever worked? The TV needs to be compatible with the correct protocol https://www.howtogeek.com/207186/how-to-enable-hdmi-cec-on-your-tv-and-why-you-should/

Also try another HDMI port on the TV.
