I had the same message. The problem was that I had two game consoles near the TV. One was functioning and the other one had this message. I guess sims TV's can only handle one game console at a time. Moving the other console to another room fixed the non-functional one for me.
This might be a new message. The last patch added in the current reward items including a new console. If I understand this game correctly, that patch must have moved functionality for gaming consoles from city living to base game. Perhaps some functionalities were changed.
This is the issue. Whichever console was next to the tv first will be the one it uses. I thought my Dream Cube was broken until I moved my Unorthobox out of the room, and then it worked fine. When I put my Unorthobox back, it no longer worked, but the Dream Cube did. So I guess one console at a time per tv. Thank you for mentioning this. It seems so simple, but then again so does thinking that more than one game console would work on a tv at a time lmao.
