Sounds an awful lot like a trip out to the dealership as the screen might be blown or a connector has come looose. I had an experiance with my Ford Edge where one of the consoles stopped working. It was out of warrany and I ended up taking it into the dealership who diangnosed it as a pannel failure. The cost of replacement was pretty steep so I found one on ebay and replaced it myself. As I now had the old one taken off, I took it upon myself to see what might have failed. it turned out it was a ribon connector that had oxidized. I could have fixed it by removing the pannel, and cut off two platic tabs. lifted the ribon cable and cleaning it with a pink erasor, then put it back together. I did try to broken pannel back on the Edge and it worked fine, but I decided as I had bought one off ebay just to use it. I brink this up as likely the front display pannel or the infotainment system are plugged in using one of these ribon cables. they are very comon.
