I posted this in another thread before I found this one, so I'll just copy the info here.
My 2011 Edge has the Black Screen of Death as well. I have had success in the past with pulling the fuse and/or pulling the battery cable, but for now it seems the unit is kaput.
Oddly enough, when I pull the fuse/battery cable the unit still will function through the steering wheel controls, but the screen is black. I can tune into a radio station, but after a minute or so the unit stops all together. The time still shows up as "00:00" on my dash display and the defrost/AC controls on the console still function but the charging port and AUX Inputs in the center console armrest do not work either.
I am sure it isn't a battery issue as I recently had that replaced with an AGM battery that is sufficiently well above the OEM specs for a battery.
My mother purchased the vehicle new in 2011 and I was willed it when she passed, so I am fairly certain it is out of warranty. What kind of pricing am I looking at to get this resolved? Having a 30 minute commute each day is tough with no stereo.
