A215 has a detachable front (grey) cover. It is attached on 4 coaks (pins). Just push a flat screwdriver under it and turn slightly - the cover will go out a little. Do it around the cover - and it will be detached. You will see 6 screws (or 4 in the left speaker). You need to unscrew them all.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Model HC30DB dead; fuse in plug ok. My iPhone was docked so
I had to open the door. The speaker covers do pop off, just persevere. Two screws
in the CD bay; to open the door I found a small gap under the door and using a
small screwdriver I could gently move a whitish cog in either direction and simultaneously
applying a bit of pressure to the door, it released. Once inside, I found a
glass fuse within the power supply casing, and the filament inside was melted. Now
to source a new one.
Dunno how old they are, but I just had an 11-year old pair of woofers re-edged because the foam surround and the adhesive had deteriorated. Upon close inspection the foam surround was noticeably pulled away from the cone in a few spots. Unfortunately, if there is an age-related issue with materials beneath the surface that you can't see, you'd have to pull the driver to check it out.
It wasn't until I turned my bass up loud that anything sounded wrong, which precipitated looking for the culprit (quickly found).
pry the speaker cover slowly using small screw driver on the side,,it has four locks giong thru..its position two at the top and two at the bottom..it is line w/ the volume control and headset..be careful not to break the speaker cover.then remove the four screws inside the hole where the speaker cover is position.remove also the rubber protector beneath the speaker or under the speaker..it has a lock beneath the rubber covering it..push the lock slowly, be careful not to break it.but even if you break it,it will do nothing..now insert finger in the hole and pull the face or pry w/ small screw driver and lift...

It took me a while, but I figured it out and successfully repaired
it. Probably not worth the 3 hours I put into repairing a $19
speaker system, but am I ever proud I repaired the set and its not in
some landfill in China
Here's what to do:
1. Remove the screw at the lower back of Right Speaker (the one
with the volume knob that is broken and without sound). You will
need a long thin screwdriver - and this screw is very, very hard to
2. Carefully remove the fabric speaker faceplate on the front side by pulling at the edges carefully,
3. Under the faceplate there are 6 screws. Remove the lower two and upper two (securing the top part of speakers)
4. You should be able to separate the back and front halfs of the speaker enclosure now.
5. Desolder the speaker stereo audio input cable from the printed
circuit board and replace by soldering in a replacement cable. I
scavenged a replacement cable by cutting the cable for a set of stereo
headsets I got for free on an airline flight. There are three
wire, white (left channel), yellow (right channel), and black
(ground), You need to remove and resolder all three wires.
6. The problem is that the existing stereo input cable develops
an open circuit somewhere in the cable for the right channel. All
you need to do is take ou the old cable and solder in a new replacement
