I am building an entertainment center which will be 22x22x65(HxWxL) . The TV will sit on top of the entertainment center and it weighs 115lbs. In order to support the weight , I was planning on putting a plywood top on the internal case and then putting a solid oak top on the plywood. How should I attach the oak top to the plywood to deal with the expansion of the oak ?

Four screws should do it - set two in the front corners from inside the box into the solid top. Set the other two in the back corners but give them slots in the plywood to move with expansion and contraction of the top, and don't tighten them down, just enough to make contact.
There are other ways to solve the problem, like sliding dovetails, but screws in slots will work just fine.
BTW, whatever you do, finish the underside of the solid top before you attach it.

If you are using 3/4 hardwood top, for the short distance you are spanning, you don't need any additional support to hold a 115 lb. TV.

48,
I believe that a 115 lb tv on the middle of a 65" long top will cause it to sag, over time. At least that was my experience with an entertainment center I built some time ago. Some sort of reinforcement from underneath will sooner or later be necessary. A rail 3-4" wide under the top at front and rear, would be better than another panel, if you have the room for them.

You're right assuming the span is not supported by interior dividers! I misread the dimensions. Thanks for making the correction.
