I replaced the color wheel on my samsung HLN507W today. After replacing it the TV comes on but does not see any of the inputs. All of the Componant Iputs say they are connected but only 1 is and there in no picture and and no signal. My son-inlaw unpluged a large ribbon cable and one with several blue wires from the main board. This is the only questionable conections I have. If any one has any ideas please respond. Thanks, Paul.
