Speakers like this aren't meant to be taken apart. They are a disposable item and only cost $20 from Walmart when they were new.
Looking at them you would use a Spudger Tool around the front edge and find the plastic clips and ease them apart. A spudger is like a blunt butter knife.

That's strange. Have you tried unplugging the BKH500 from the power source and then plugging it back in? That can sometimes reset the device. Also, make sure that all of your connections are secure and that the device is properly installed. If you continue to experience problems, contact Brookstone customer service for assistance.
Here's a simple guide to fixing your Lenox CD-90 CD player:
Clean the lens: Dirt and debris can cause the laser lens to stop working. Clean it using a lens cleaning kit or microfiber cloth.
Check the belt: The belt that spins the CD may have become loose or worn. Check to see if it needs tightening or replacement.
Reset: Disconnect the player from power for a few minutes and then reconnect it. This can sometimes reset the player and get it working.
Professional repair: If the above steps don't work, consider taking the player to a professional for repair. Although this may cost some money, it may be worth it if you're attached to the player.
Note: Always unplug the player and follow safety precautions before attempting any repairs.
