Did you turn on 3D mode on the TV?
I have a 65737 and starter pack and set mine up with a Harmony remote to be to push one button to watch 3D. The other night for the Homerun Derby I thought all my glasses were dead. Turns out, for some reason the macro did not turn on 3D mode on the TV, even though the adapter was showing the merged, single fuzzy picture. Once I navigated to the menu and turned on 3D mode, everything was fine.
You have to hit the adapter remote until the two images merge into one fuzzy picture, then make sure that 3D mode is turned on on the TV. Unfortunately, Mits TVs do not seem to do a good job of auto detecting the proper 3D mode or even when there is a 3D signal in order to auto switch to the correct mode on the TV.
Good luck!
