BOSE Companion® 3 multimedia speaker system in Chapel Road, East Singapore for sale

This items is currently not working, need to be fixed.
The Bose Companion 3 is a great-looking, solidly built three-piece system that produces moderately high volume levels, snappy bass, and a delightfully transparent, spacious midrange. It lacks deep bass output and is a bit too bright for our taste, but neither of these flaws is enough to negate its formidable strengths.
I bought the speaker system long time ago in Japan. It's for 120V, needs transformer in Singapore just for your info. After long time no use, I tried to use, but doesn't work anymore. Then I decided to open the cover to see what's wrong in there. The last pic shows that there are some damages to open the back cover. After all efforts, I realised that it's impossible to open. For those who have better idea to repair and make this speaker system function again is most welcome. Just come to pick it up. All necessary parts are included.
