I was able to buy a used 55" Vizio that had become "bricked" after it lost power during an update for $50. I replaced a $60 board and it was as good as new. Also, got a 55" Sony for free, similar situation. All it needed was a firmware flash via USB (was very specific as to USB size/format), and it works fine. None of these TVs are connected to any network, nor will they be ever again (as long as I own them). Also, I see Amazon has a 43" Viewsonic "commercial" 1080p display for ~$450: http://amzn.to/2iu2cCB http://amzn.to/2iu2cCB. I know, they have a TCL 55" 4K w/ built-in Roku for $50 less.
