I have a problem with my empeg Mk 2 player.

Firmware: 3.00-alpha11
hijack 471

When I boot it, it seems ok, and everything shows ok on the screen, but after it go blank, and the little blue diode starts to blink, it won't react to anything, either pushing any of the buttons or using the remote. So I can't turn it on, neither in my car or at home.

When I put the usb cable in a computer, the computer finds the
device, and it's possible to install the usb driver, but emplode
doesn't find it.

Any idea what the problem could be and if there's something I could do myself to fix it?
