Audio Systems: dvd player malfunction, 07 chevy tahoe, chevy tahoe

Question
I have a 07 chevy Tahoe with a flip down dvd screen in the back. Im getting sound but no picture.(NAVIGATION SYSTEM) PLEASE HELP

Answer
First thing to check is the video cabling to the display (if you can easily get to it).

Do you have video on DVD?  On NAV?  If no video only when playing dvd it is likely the output cable or the video driver within the dvd player.

Some of the flip-downs do not make good connection when the display is brought down or it may not be down all the way.

If the above ideas don't yield anything you will need to take it in for warranty repair.  (If, for example, it turns out the display is defective it could be a very expensive repair, so hope it is still under warranty).

Let me know if you have further questions.
