I have a Jensen VM9224 installed in my car and for the first two years I had it, it was working fine. A couple of months ago I would turn on my car and it would look like the screen was cracked, and it wouldn't work for that day, then the next day it would magically work fine again. Sometimes it works, sometimes it doesn't, and its really annoying. Does anybody know what could be the cause of this? Because although it looks like the screen is cracked, it definitely isn't.
