I had an Amazon Fire TV Cube for my new TCL Roku TV and it worked great. It especially could turn the TV on and off via command.
However, I did not like the audio on the TV so I thought I'd move the cube to another TV and get the Beam for this TV. I'm using just a plain Amazon Fire TV with the TV.
The Beam definitely has better sound, but I can no longer turn the TV on or off.
First, yes I have the CEC settings correct. I have connected the Beam to my Alexa account, and set it up as the device to control my Amazon Fire TV. I can search and pull up a movie and control playback. My Bean is attached to the ARC HDMI input.
But I cannot turn the TV on or off.
This is an issue because the Beam is so large, it covers the TV's remote signal detector and I have to stand up to be able to get the signal through to turn the TV on or off.
I've seen other people have problems with turning tvs on or off, but I haven't seen any solution. Is this just not a function that the Beam controls?

As far as getting the tv to work with CEC, this post is pretty helpful.
I would remove the fire tv stick temporarily, power down the TV (maybe even unplug) and then restart and see if the commands work then as a start, but it's worth trying everything that applies for your situation.
One other thing to try is to 'target' your commands by specifying the room name. For example, "Alexa, turn on the game room tv". I have to do this with my setup as alexa always assume I mean the tv connected to the firetv cube without specifying the room.
Lastly, it's possible that your tv just isn't 'listening' and won't accept the commands through CEC no matter what you.
