Has anyone else experienced an intermittent LCD screen on this model? I hooked up my new unit and it worked fine. I went in to get some test CD's and came back out and when I started the car it took 5 minutes before the screen illuminated. It happened again this morning but did not happen the next two time i started the car throughout the day. The left and right sides illuminate but the center LCD takes a while when it happens?

I talked to TECH support and they said they have seen only a hand full with LCD problems but thought I would run it by you guys.
