My Bose 3·2·1 Is Not Playing a DVDby Irene A. Blake
The Bose 3·2·1 Media Center is the main music and video component of the Bose 3·2·1 Home Entertainment System designed to play a variety of discs including CDs and DVDs. When a DVD won't play, one or more issues may exist with the cable connections, power, disc or center. The only way to locate the source of the issue and attempt to correct it yourself is to check and rule out each possible cause.
Check that you have all of the cables and power cords securely connected into matching jacks and sockets.
Remove the batteries from your remote and insert two new "AA" batteries. Press the "Play" button again to see whether the remote control originally lacked sufficient power to issue the disc playback command to your Bose 3·2·1 Media Center.
Pick up the DVD box and compare the region code on the box to the code on the bottom of the unit to make certain that you've inserted a disc that's compatible with it.
Open the player disc tray if the region code matches. Check that you've inserted the disc correctly with the label pointing up and the disc inside the tray guides.
Lift the disc by its edges from the tray, turn it over and check for scratches or fingerprints if you inserted it correctly. If the disc has marks or damage, clean and/or repair it with a DVD cleaning and repair kit.
Reinsert the disc. Push the "CD·DVD" button on your remote, wait five seconds and then push the "Play" button.
Eject the DVD and try a different one to determine if you're dealing with a defective disc if the current disc still won't play.
Pull the power cord from the electrical socket while the unit is powered on to perform a "hard reset" if the problem persists with a new disc. Wait 60 seconds. Plug the power cord back into the electrical socket, turn it on and try playing the disc again.
