No idea what could cause such a failure other than serious misuse (plug output into mains outlet..?). Surely no shipping damage! I think too that you should first contact the seller if he promised fully working condition. If it's just the resistors which got burnt this will be easy to fix, but if the output transformer suffered too, this will be expensive if at all possible (I think the SYS-2722 still uses the same transformer, so you might get a replacement in case).
