hey whats up guys. ive had this stereo for a couple months now. but i just put a dvd in today. and only sound plays. no picture shows up...

doesnt it play dvds?
and yes, i have the e-brake up.

i think it may be cuz my stereo is on some demo mode. i bought it from bestbuy off the shelf for a 100 bucks less. but i knew they had put it up just a day before. so when i take a CD out, it goes through this demo mode going crazy. you think this is why dvd's arent showing up?

cd's and my phone plug in fine. but no dvds, just sound from the movie

 

mine says demo mode too when i have nothing playing. did you try another DVD??? i've tried one DVD where it plays the movie but no sound tho but not the other way around.
