This forum is very helpful.  I have an issue with Mt 2 year old AVIC 7200 NEX. A few years ago I updated the software with the hero from this forum.  Everything seemed fine until today. Was driving down the road, looked over and black screen. Hit the reset button and get a white screen briefly with a vertical gray line for like 1/2 a second then black. Put truck into reverse and no camera display. Thoughts? Fixes? Thanks in advance

Still not working. Even when reset. White flash black pioneer logo black. Touch screen works fine. Is there like a fluorescent light behind the screen. Almost seems like it fire and then tries again.  Or is it an internal SD card?
