I recently bought a UN40H6350A TV. It's properly connected to my WiFi network, and can stream from NetFlix and so on. I installed the Smart View 2.0 app from http://www.samsung.com/ae/support/smartview2/ on my PC running Windows 7 Home Premium SP1, fully updated.
After running the Smart View app on my PC, I click the "Connect to TV" button. It correctly finds my TV and shows an icon for it. However when I click the icon, nothing happens. The (very brief) instructions suggest that it should offer a dialog for entering a PIN displayed on the TV, but that doesn't appear.
The PC normally uses a wired connection, and I also connected to the WiFi network for this purpose. I tried disconnecting the wired connection in case that mattered, but I got the same result.
Anyone have any ideas?
