It's possible that you need to go into Service menu and activate KR3D.

KR3D OFF (ON, OFF) Enabling 3D shutter glass emitter

It is not clear what this emitter is. It is most likely Bluetooth (RF) in newer
models, and IR in older ones. However, we don't know exactly how this works,
so don't blame us, if something goes wrong...
