I don't quite understand your issue. What do you mean your eyes won't come on? Do you mean your eyes aren't lighting up the the breach? Do you mean your rate of fire is slow with the eyes on? Are you shooting paint or are you blocking the eyes and trying to fire?
If you are not shooting paint and you are blocking the eyes continuously it will cap the rate of fire to 8bps because it thinks the eyes are dirty. If you are shooting the paint and this is happening you should clean your eyes. See the manual at paintballsolutions.com/empire if you have any more questions about how to use the marker.
