How can i delete a netflix account from my panasonic viera tv without accessing the netflix account?

Disregard the other solutions. Open your Netflix App and do the following:
Hit the arrow keys on your remote.
Up, up, down, down, left, right, left, right, up, up, up, up.

My changing accounts was a little different.... I was a previous customer who cancelled, then had a family member over who wanted to log into his account.... this is what we did: Click the NETFLIX button. Once you are in, let the red screen complete... when you get to the menu where it says Start (as in resume membership, enter CC info, etc) On your tv remote do this: Using the arrow buttons ~ up up down down left right left right up up up up. The screen automatically popped up to say BACK or START OVER. Click Start Over then it prompts you to log in. We have Panasonic, Plasma.... hope this helps!!

To delete a Netflix account on your Panasonic TV you have to reset the settings/memory to factory defaults. ****WARNING**** all memory stored will be deleted take precautions to write down any desired settings or network information.
1. click menu 2. scroll down to setup(wrench icon) 3. scroll down to reset defaults 4. create a password 5. Reset all settings to default? click "yes" 6. Follow all directions to configure your television.
When you open Netflix via VieraCast your Netflix account should give you a code. Sign in from your computer and enter the code.

Change the code to an incorrect code and save it.
