One last try before recloning.
Disconnect everything going out from 3da-1.
Turn sat and tv off.
Turn sat on, channel 103, them tv on. You should have message, no connection. Wait a few seconds.
Next steps do exactly , they don't make sense...
Plug out from Gefen directly into HDMI -3 (Previously renamed to STB Satellite) and wait several seconds.
Have the Gefen which is disconected from everything in your hand.
Disconnect 3da-1 from tv and plug it into input of the Gefen...The green light should light...wait a few seconds...
Now, plug the out of the Gefen into HDMI-3, and wait several seconds for the resolutions to fix.
If you get this far, then you should be able to activate 3d in the menu of Samsung. It is located on the remote at "Tools". The top line should read 3d--off, scroll left to mode 2. After it works, toggle between mode 2 and mod1 for best 3d picture.
As mentioned earlier, it should default to checkerboard and you should not have to change the mode on the 3da-1.
