Do check all the fuses. It's easy to do. Don't stick your hand in there unless you've had it unplugged for an hour or so as the filter caps can hold a substantial charge,  enough to kill

If any fuses are bad only replace that fuse with the exact same value fuse.  If the fuse blows again then it's time for the receiver doctor.
