Sony is losing a lot in the TV market, same as Panasonic. I am not sure you can "fix" the TV market, since the TV's role is still changing, and hardware innovations become less and less important, so there's no way to go back to the boom of early LCD. I personally would like to have a "dumb" instead of a "Smart" TV, basically just a huge display to which I can hook my PC or whatever box I want. But it'll take some years in which the big guys will desperately try to keep the old ways alive.

e: previous version of this comment said Sony's Imaging division was quite healthy, while they are losing money too. But as mirrorless is a new market, I guess it's worth to lose money to establish a good market position.
