It is not under warranty I bought it used.
Are you sure you connected the power in the back tight and secure?
Second one might be fuse, and my last but not least might the unit itself.
Try doing this first though, disconnect both terminals of your car battery, wait bout a good 10 minutes then re-connect see if the problem goes away
