i'll start by saying whoever programmed this for the X85c models needs sacking. Turning on 3D shold be as simple as pressing a button but instead its hidden in the action menu but also disapears from here if the TV decides (incorrectly for 90% of the time) what you are trying to play isnt 3D compatible. If you start a 3D movie and then try to turn it on, its missing in action, if you access the USB drive, its not there, if you turn it on and then load and android app like KODI, its turns off.

What a total amatureish mess, this essentially makes 3D not fit for purpose , needs sorting asap please.

i've logged a general call with sony about this ref: 13021366
