I had to disconnect my power cord for my LG 55LM6700 to route it through a wall. Unfortunately it's a non standard cable with three wires that connect to a circuit board connector. I removed the connector without remembering what the order of the wires were. I don't want to plug it back in and fry the TV without knowing if I got the wires in the right slots. Here's a pic of how I reconnected it. does anyone know if this is right?
