dvd module not powerin on
 

hi guys..
please i need help with a rather confusing issue. i have a 2005 vanden plas that has a video entertainment system, well it has been working nice(monitors at the head rest and dvd module in the trunk).but i had issue with my cdc at the trunk and i took it out and replaced it with a fiber optic loop cable cus the whole radio system wouldnt work without it(lame tech). anyway, ever since that happened my monitor at the head rest still turns on and works fine but my dvd module at the trunk seems not to be powering on, even when i put a dvd in it, it doesnt power on and wont play. is there something i am missing??
help pls...
