Hmm. I echo Sidssp's sentiments. I'd be leary of that classified description as well and ask the seller what warranted the trip back to the manufacturer.
From my own experience sometimes I've gotten gear that had been sitting dormant for years without being powered up. If I had easy access to the original manufacturer I'd send the piece of equipment to have them review it. Otherwise it would go to a very competent tech to check the item out. I'd do this though if I was really attached to the piece of equipment or if it were an expensive item that I would sell.
