Did you solve your design dilemma or find an answer to your question? Very, very few designers monitor the Other section of Houzz, which is why it took so long for you to get a reply. If you desire design advice, please post this again in the Design Dilemmas section, preferably with as many photos as possible. You will get the best suggestions that way.

You will have to probably redo the shelves completely. Looking at how they are built you cannot just remove the middle to put the TV in. You may be able to put some support under the shelf that will be just above the TV....just consider this. I would paint the inside of the shelves a fun color- cobalt blue or burnt orange maybe. This will give you a great backdrop for your things and keep the TV from becoming a black box on the wall. It's a great space!
