Okay - do not panic !!!!!!! Have your friend call Wicked (or email them) they have a 90 day warranty, right ? As long as it has not been over 90 days, you may be able to return it, and get a new one back. I coulda sworn that they stopped selling the CNI modela a long time ago....are you SURE it is a CNI ?
I am Guessing some damage has happened to the MCA (crystal set) maybe knocked out of place slightly. The fact it is lasing at all seems to suggest the pump diode is kicking out enough power and that is not at fault. (but I could be wrong).
Have you tried new batteries? if you have, then I suspect it is dying
