On my Dynex DX-RC01A-13 tv I got to the point of entering my account email but there is no keyboard on screen to use to enter it. The Roku Express accessed my internet connection and I have the Roku "Activate your Roku player" screen. I'm stymied. Any help would be appreciated.
When you get to the "Activate your Roku player" screen, you will need to use a web browser on a computer/laptop/phone, etc in order to link to your new Roku Account (Follow the on-screen TV prompts and use the activation link sent to your email.)
You can review setup in this link and watch short video. Step 4 covers the Activation process.
