Maybe a nice rectangular artwork the same width of the cabinet above the TV or an interesting fabric wall hanging to match your decor...or you could have, again above the TV, a timber shelf that matches the timber in the cabinet or that in the floor...or that is painted to match the wall colour, having an ornamental front that would hide the power points....Did that explain the shelf? I'd do you a sketch if I knew how to upload it. Unless you are a minimalist you could have one or several interesting objects d'art on the shelf (no flower vases with water) or some books with classy-looking spines in a row between ornamental or plaiin book ends.

You could mount the television on the wall.

A simple solution if the power points were still easily accessible.
