Family area corners or badly-lit regions of the room need to be lightened, as with all rooms. You can do this using any combination of plants, mirrors, art work, lights and pale colours. All of these attract chi that might otherwise be missing. So place lights so that there are no dark corners as part of your living room, and the lights provide the extra good thing about brightening the whole room. Televisions and other metal-based objects (such as music systems, metal tables) really should not be placed centrally. The electromagnetic waves may disrupt the flow of chi, rendering your other efforts useless.
