Hello, I had my Hi-FI Speaker in the same conditions.
I don't know what happened with it. Suddenly one day it stopped working. I tried to repair it in an Apple Service Store, but they did not receive it. The reason, warranty had expired.
Since I bought it, I have used it few times (my wife hates to listen music in my room). Probably if I sum my Hi-Fi working hours, they are less than 50 hours in total. The funny/saddy thing is that the equipement stays just in front of my bed, like the first day when I took it out from its box. It seems brand new, without any scratch, but it does not work. I see it every single day.
Something weird happened four months ago when I connected again my iPod and the HiFi worked. Everybody here were surprised listening music coming out from it. But, when as a try, I took out the iPod and connect it again to the Hi-Fi, it never works again.
On the other hand, I had also tried to open the equipment, but I didn't find any screw. Every screw is hidden.
Does any body can give me some tips to open the Hi-Fi or tell me what probably is going on with it???
I will appreciate any tip from you.
Thank you
