At the fundamental level, you need a computer program which can open Word documents, whether that is Microsoft Office, Microsoft Word viewer (it's free), or one of the various free copy-cat Office programs.
A TV isn't going to have the software required to view a Word document, so plugging a USB stick into the TV will not allow you to view the Word file. Although, a TV will play jpeg images or mpeg4 video files from a USB stick.
If you need to view a Word document on a TV, here are the following options:
- You need a TV which supports Miracast. Miracast allows you to "project" your phone, tablet, or laptop screen to the TV screen.
- If your TV doesn't support Miracast, you can get a Miracast adapter and plug it into your TV.
- You can then use Microsoft Office on your phone, tablet, or laptop to open the Word Document and use Miracast to display your phone / tablet / laptop screen on your TV screen, which will show the Word Document that you have opened on your device.
Think of it as using your TV as a wireless computer monitor. The Word document will need to be running from the "computer" first.
