Black screen x350 2003

Recently I have a problem: a black screen. can’t do anything with it. buttons do not respond. I understand that the code has something to do with the NAV. I disconnected the battery for 36 hours. then fully charged. no result. can be found in a menu. NAV + AUDIO + TEMP UP but I can’t do anything with it. I took out the navigation DVD and put it back in. no result…

anyone have any idea how to solve this?



I can only guess that the video driver in the AV module has failed. These complete units are sometimes available on eBay. I also suggest that you search this site for “X350 Video failure.” Then again, it cannot be the main video driver or you wouldn’t see the menu either. Sorry, I’m stumped.
