How about sitting on the sofa in the living room, facing west to east?

It depends on the specific layout of your house. Generally speaking, the sofa can sit facing south, north, east or east. If the balcony is in the east and the entrance door is in the west, the TV background wall of the living room must be placed where you can see the background from the door. If you are not at ease, I suggest you find a Feng Shui master to serve you at home.
