If your satellite is in the component jack and does not have the lines, you have a bad doubler or 2HD board. These boards are located in the metal container on the left side of the tv (left as in when you are looking at the back of the tv).

I have the same issue with my 73". Rather then going over all of my connections and equipment I'll just say htat I feel your frustration. I have been on the phone with Mitsubishi directly and it appears as though they have a free software upgrade that should address this problem. If you call 1-800-332-2119 and press 4 in the menu you will get someone to help you. Be patient. They will make you go through all of the fixes that you have already tried. They will mail you a flash drive that goes right into the front USB port of your TV. I hope this is of help. Good luck.

Simplest thing would be that your component cables are not HU'd correctly. Having them reversed would do this.
