Netflix, can one

I wanted to create my own account on my Sony Bravia television via the Netflix app. Unfortunately I'm always the account of a friend displayed, how can I delete this account of my tv device?

Log in to your Netflix account in a browser.
Click the Account option.
In the My Profile section, click the Manage Profiles link.
Select the Edit icon next to the profile you want to delete and click the Delete Profile button.
