Did you get this about 2 years ago with the purchase of a new pana plasma? Mine died a couple of weeks ago also (power supply i think) and I ended up with a set of Monitor Audio RX8s and a Denon 2313. Can recommend the Denon, and highly highly recommend going separate AVR and speakers if the budget allows. I ended up going quite a bit over my intended budget but boy am I glad I did...the sound and details from these things are a million times better than the HTIB.
Good luck
Sorry to be the bearer of bad news but I can't find it anywhere!
I saw it just a few weeks ago so know it can't have gone far, probably buried somewhere in a 3 year olds toys.
I'll keep an eye out, but you probably should keep looking.
Good luck!
