Uploading Software to a Technobeam?

Okay. We are trying to fix a techno that seems to have lost the software. It will power on as far as junk coming up on the display. I was able to find out that the technical training stuff says that means a blown fuse. However the fuse is good. Does anyone know if this is in fact that it had lost software? Or are there other causes?

If it's software, does anyone know how to force it to upload new software? It won't go into the menu so we can't put it in UPLD. I know HES can reprogram boards that lose everything, how would I do this?

Thanks!

PS: I may have to call HES or Strong, but I figured I'd ask here first.
