The "eye" on most Mitsubishi sets is next to the green CRT. Typically, you can see the eye, and get close enough access to place an emitter, by pulling the front service panel. I would like to say that you do this at your own risk, there is some significant danger in touching live components even if the set is powered off and unplugged. Removing the back panel of a rear projection set also carries some risk in that there is a fragile mirror typically attached to the back of these sets.
