Query: Could have started my house on fire!

I had my HTS3555 for almost two years when one day it wouldn't work. I went up to it to find out what the issue was and it smelled like burned plastic. I plugged it to a spot where I could see the back more easy and when I turned it on again, it was sparking and smoking. If I wouldn't have come home when I did, my house could have burned down!
