I ordered a Samsung UN55D8000 (2011, led) that came with a 3D kit. I ended up returning the TV because of a defect, but decided to go with a PN59D8000 (2011, plasma).
I paired my glasses (they use bluetooth) with the first TV, however since the kit is supposed to be compatible with both tvs, we were told to keep the kit.
Now however, the glasses refuse to pair with the new TV. When they are turned on, they just blink green and red for a few seconds (though or sometimes longer).
I've taken the battery out, held the button down for varying lengths of time. Got the glasses close to the tv, far away. I can't think of anything else to try, other than exchanging them.
