We just recently noticed this. Running the Pandora app on our KDL-46XBR9 will reboot the TV. It will load the app and let you select a station, but when it tries to load the station it appears to start loading a song, then the tv shuts off and restarts. This only seems to happen with Pandora so far. Slacker, NPR and Netflix work just fine.
Hello Frog, So far no other users have reported this to us, Might I suggest disabling all your stations and create a new test station? perhaps a specific station is causing the error. or test with another Pandora account. try unlinking your account in my essentials and relinking if that does not help.
