I have Nakamichi Soundspace 8.5 home theater system. When I play dvd it's giving me message that "This Disc Is Not Formatted To Play In This Region" any answers?

Try to find out by looking at the menu of the dvd. play the DVD without a CD Rom in it then press stop and menu at the same time. It will let you select a region for it to play. But sometimes you can only do that with a different DVD players. so0me DVD players are only made to play on what you already have it on.

check your power cord, check your 9 prong relay cord from power amp to deck unit, check your fuse that is in a little slot in the plug itself, most importantly check the 9 prong plug to the control unit itself, if you are mounted on the wall it could easily come out enough to not make connection. these units will take alot of bad voltage errors, if the only thing not working is your cd player you should still be able to eject it, if not it is power related, if it will eject but not play then your drive band is broke and unless you are very very mech minded take it to a repair shop who is nach. refered just look online for service try my ideas 1st you might get lucky, I hope I am right!!
