WANT EJECT 5 DISC DVD RCA THEATER WANT OPEN NOR EJECT . CAN U HELP ME?

I am not sure about the d5/5 error but you should be able to eject the disc by performing the following, which I took from my user manual.

Turn off the unit. Press and hold the [ >>/>>' ] and [ OPEN/CLOSE ] on the main unit at the same time for about 5 seconds.

Hope that helps.

Plug the power cord back into the electrical outlet and turn the player ON. Attempt to open the disc tray. Depending on the model number of your DVD player, simultaneously press the POWER + STOP + EJECT buttons. If the disc tray still does not open, simultaneously press the DISC1 + STOP + EJECT buttons.6 Jan 2013

My identical system has exactly the same problem as the one described by dipaola, above. When I insert a DVD, the DVD carriage pops back open after a few seconds. In fact, mine won't stay closed even without a DVD in it, as long as the system is set to play a DVD. I'd like an answer to the big Q - Is there anything I can do about this, or should I just find another DVD player to hook into the system?

Unplug the power cord for ten min. then try again.............. John

To unlock the JVC TH-C5 disc tray is by having the system off and at the same time hold the stop button and eject button until it says, "Unlocked". 

I was able to fix this problem by disconnecting the Bose power cord from the back of the unit. When I reconnected it the door functioned again. Cleaning the disc helped avoid further lock ups.

you should never use a disc thats scratched inside yiour machine its most likely your dvd machine is having trouble reading your media the best way to solve this is to unplug your machine wait turn it back on keep pressing eject it should eject dont use that dvd disc again hope this solves your problem did for me ;
