I can not sign out of netflix on my vizio tv.

the base account allows 2 simulations connections
eg : streaming 2 TVs same time.
to long in use your user name and PW
that is all there is to that.
no sign in to your account, unless, you like giving them free money?
no rooku does not
netflix, memorizes your device names .
so it can stream based on what it wants and needs
that means you need to sign in one time,
on each new device. used.
TV , rooku , DVD smart player. etc.
all are devices and very different.

It depends where you are trying to access your Netflix account

if it's your TV you will need to add the Netflix app to your menu, open the app and sign into your account using your TV controller.

if it's your IPad
add the Netflix app in App Store and log into your Netflix account

Is it asking for your user code. You actually have to go to your account on netflix website and enter in what tv or blue ray player you are using and it will give you a conformation code that you enter on the device itself when trying to log in and it should work fine. You must activate it in the Netfix account first and it is free of charge.

I had the same problem with my Vizio XVT473SV. I couldn't find the Netflix Activation Code. When I clicked on the Netflix App, the TV would ask me if I wanted to connect to Netflix, then it would ask me if I was a Netflix member. After clicking yes to both, it would tell me it couldn't connect to the Netflix server, check with Netflix.com/tvhelp. After a couple hours of troubleshooting, the solution was......your first use of the Netflix App has to be via the Ethernet Port/Cable. This will give you a screen with the Activation Code, after you activate the code in your Netflix account, you can go back to using WiFi on your Vizio TV to connect to Netflix. Step by step instructions are...
1) Exit the Vizio Netflix App.
2) Physically connect an Ethernet cable to your broadband (just temporarily)
3) Check to make sure the Vizio is using the Ethernet port and not your WiFi (Apps Button - HDTV Settings - Network...may have to reboot the TV to get Ethernet port connection)
4) Start the Vizio Netflix App
5) Click OK to start the Netflix App
6) You should now see a different screen that gives you the Netflix Activation Code.
7) On your Computer, Login in to Netflix,
8) Click on "Your Account & Help" link on upper right corner
9) Scroll down to Watching Instantly on your TV or Computer section
10) Click on Activate a Netflix Ready Device
11) Enter the Activation Code shown on your Vizio TV and click Activate
12) Once your Netflix account (on your computer) shows it is active, your Vizio TV will automatically log in. You should see your Instant Queue.
13) Exit the Netflix App, unplug the Ethernet cable, Turn Off your Vizio TV.
14) After 20 seconds or so (remember the TV is software driven), turn the TV back on and your WiFi should connect again.
15) Use your Netflix App and this time it should automatically connect via WiFi
note: just make sure that your wireless DSL/Cable Modem or Wireless Router is not blocking your WiFi connection request from the Vizio. You can check the connection status in the modem/router or in the Vizio in the HDTV Settings - Network.
