I just had this issue happen to me. About 6 weeks ago, upon ignition, both radio & HVAC displays were blank...I immediately just shutdown and restarted the car, and all was fine. Well, last night when driving home from work...I happened to notice that parts of the radio & HVAC displays looked funny....I could see thin horizontal red lines between the pixels...and some pixels were missing...and different parts of each display were dimmer than others and were flickering just slightly. So I got home...left the car on...took some pics (in case the issue magically repaired itself). I then shut the car off. Then I turned it back on....and both displays were blank. I restarted it again....and got the same result. So, I tapped the side of the console lightly with my knuckle....and the HVAC display came back on. Everything appeared to be functioning besides the display. I called the dealer, and they said I could stop by and they'd have a tech verify...and order a new unit. I also noticed a slight hum coming from the unit that wasn't there before.
