This TV do not bare the weight of Netflix. So poor!!!

Go to Best Buy and get an Apple TV for $69. (It's not aTV set. Just a little box that connects to your wifi and streams content to your T v. You hook up the Apple box, change the tv to the hdmi port you plugged it into and get your wifi connected to it. Then select Netflix and log into your account. Or wait for the new Apple to be available for $200. You can also get an Amazon Firestick from Amazon but you will like the $69 Apple TV better.

Hello.
To stream on Netflix your Netflix account has to be set up to stream.
For Netlix user's your account would be either streaming OR playing DVDs, not both.
If your Netflix is set up to stream, you may need to download Microsoft Silverlight which is free and availble from Microsoft.
Be sure to download the latest version of Silverlight.

You will also need to open Netflix.com and create an account on your computer.

Close netflix and reopen after creating account then login.
Then check your account for streaming or DVD playing.

Depending on why kind of TV you have to watch a movie you will need to connect to the TV with an HDMI cable.

I could be wrong but here it goes, When I go to Netflix online to set my device to watch streaming TV and videos through the TV it asked me to type in the code I got from Netflix not sure if this works for the other streaming media programs using this device it does with Netflix. Once I have done this I log in and it activated itself. Thanks for using FixYa! "Guru" John
