I recently purchased a WB68 and had one hell of a time to get it to work. When I called Zinwell, their response was, "Try the satellite setup again. It could take up to 10 times." I finally got it to work. I moved the rack slightly where all the equipment is located and one or more of the receivers stopped working (I just woke up and don't remember). It worked for a while, then stopped. I reconnect all RF connections between the WB68 and the receiver, and reset the receiver (I don't see a way on this Samsung receiver to repeat the setup through the menu). Some times it works, some times it doesn't. This particular receiver has flaked out 4 or 5 times since yesterday afternoon when I moved that rack.
