Unfortunately, Nintendo's Error Code Lookup can't seem to find the 157-1103 error code, but it sounds more like this is some sort of repair issue, sorry.
So perhaps you might want to give a call to Nintendo's 1-800-255-3700 (6 am ~ 7 pm Pacific, everyday) Customer Service number, and one of the service representatives can do some over the phone troubleshooting to determine exactly what the problem(s) might be, and then set up the repair process if that turns out to be what is needed.
