I think I would try to figure out a new vision for SONY and try to align their operations to that vision. Currently I feel that SONY is a bit of a mess in terms of R&D and products.
Also work on the culture within SONY especially their R&D. I think they need to be more integrated and focus on innovation, which may be too much of a strech from their current operations. So it may need to be a long term plan.
They also need to invest heavily into consumer research.
