A:AnswerThere is not going to be an 85" of this model, but the 100" Z9D ships in November to the lucky few who were able to get the first round of pre-orders. I hope to see mine by January.
A:AnswerDepending on how long ago you had the tv swapped you should still be in the return/exchange policy. Even if you're not you're upgrading so the store should make the exception, I know my store would.
A:AnswerTry doing a hard boot, unplug the tv and wait 2-3 mins. If that does not work, call sony, they can tap into your tv remotely and do a software update / diagnostic test
