Summary: "F70" Same problem as the other reviewer. I have had this receiver for 9 months and now it is again dead. The F70 error means that an internal fuse has blown. It is not user replaceable and you must send off to repair center. Edit: Based on further info, I upgraded from 1 star to 3 stars. As it turns out, the fuse in question is a standard 2A/250V fast blow fuse available ... at RadioShack. Any local service place can replace it for you in about 3 mins.
