Mbox Pro 3 doesn't turn on!

I bought a MBOX Pro 3 about two years ago. It worked perfectly until the last weekend when the power light started to blink and I lost the connection with my computer, so I checked the Avid Support Forum and found that maybe it could be the driver, so I decided to update it from the Avid Drivers Page. I was using the 1.1.9 Driver for Windows 8 with the 1.0.3 firmware and I found in the Avid Mbox Pro Drivers page the new release for windows 1.1.10 that include the firmware 1.0.4, so I downloaded and run. The update started normally, but in the middle of the process it stopped, I know that you can´t shut down the computer in a firmware update, so I waited for 6 hours, but it doesn’t finished. So I reboot the computer and the Mbox, but it doesn’t turn on, now the Mbox is completely dead.



I would never think that a driver update could do that with a piece of hardware, but definitively this´s something that must be fixed by AVID.



Any one knows how do I restore the MBox 3 to the original factory settings?



Thanks!
