Triggering an animation after player triggered another beforehand?

Hi,
In my project I have a Playstation and a TV. When the player starts, both are off. What can I do to make sure that the player can only turn on the TV after they turn on the console using the same trigger key (in this case ‘E’)

I tried using a boolean ‘isconsoleon’ and it works if the trigger keys are different, but when using E for both, they play at the same time. So what I need is a way to block the TV trigger until the console turns on.
This is what I have at the moment:

Any help would be super appreciated, thanks.
