If I understand the problem correctly, the servo or motor that moves the lens in order to align the colors was damaged by the power surge. The satellite line transferred the surge to the inputs, charring the wires and probably severely oxidizing the contacts. Just recently, the mounts for the lens had more abuse than it could take from the combination of the lightning strike and repeated attempts to realign it. Your only hope is to take the TV apart and remount the lens (I doubt that's going to happen, and even if you did, you probably wouldn't get it perfect unless you're a veteran TV-repair guy.)
If you do decide to take it apart, you'll need to be careful not to touch any capacitors or voltage sources, although I don't think the lethal-current ones from CRT TV's are present in projectors.
