Dead S100 Head Unit After Rough Start

[QQQO]

Hey guys. I've had the S100 unit in my car from for a few years now with no issues at all. It's really been a great unit. However earlier tonight I experienced a hard start, and while it started on the first try, the head unit did not power on. Figuring I may have blown a fuse due to the rough startup, I checked to see if the radio fuse was blown and it was not. But my unit still no longer powers on. It seems there's no power going to the unit at all. None of the button lights or screen turn on. Any idea what's wrong or what I need to do to get this resolved? Thanks in advance for the help!

Just wanted to provide an update and resolution to my situation to serve as a reference for others who run into the same issue. The problem was not with the unit itself but was caused by a weak/dying battery. I had it replaced and the unit powered on as normal. No other issues to report. I'm guessing there wasn't enough amperage to power the unit at startup, so it just failed to turn on. Phew! Hope this helps!
