I like the Sony 850C as our entry level TV, but it has bugs. I have had a client complain that the Crackle app "ad" would pop up randomly and no button press could get it to go away (researching that is what learned me that Sony owns Crackle...go figure). He had to power cycle the TV. Disconnecting the network fixed that.

I have seen several of them automatically switch to HDMI4 all on their own randomly. There is an issue with Yamaha RXA750/RXV679 AVR and certain sources....intermittent or no video and/or audio. Yamaha and Sony engineers are both aware of the issue and are working on a solution. The latest updates did not include a fix according to Sony CIS techs. And 45 minutes for an update is awesome.
