Where is the wifi chip on my Galaxy tab S 8.4 wifi?

The Wifi is broken (switch greyed out, won't turn on). I believe the chip has failed and am looking to replace it. Do I need a new main board?

Is this a good question?

The IC itself is a BCM4354KKUBG

Unless you have the ability and the tools to reball this IC you may consider a new board, a reflow or send the board of to someone to repair it for you. Replacement motherboards are available at places like this.
