New guy here, so sorry if this is an obvious answer. I bought a 1998 Maxima about a year and a half ago and it came with a model CDA-9811 Alpine head unit.

About a month ago the problem arose. If I am starting the car cold (at least 3-4 hours since it was last driven), there is no problem. But if I start the car after being recently driven (after getting gas, coming back from inside the store, ect.), the head unit will turn its self on an then immediately back off for anywhere from 10 minutes to an hour or more before it will finally stay on. There really is no rhyme or reason to it either. It can turn its self on and then immediately back off or sometimes can stay on for a few seconds. It will also go from as little as a few seconds before it tries turning its self back on or go as long as ten minutes before it tries to turn its self back on.

An other thing I notice is a faint click, almost like a circuit breaker or fuse pop when it turns its self off. Im about to toss it out the window but thought I would ask around to see if its an easy (or easier) fix before doing so
