Try resoldering the main bridge rectifier on the power amp circuit board. You will have to remove the board from the heat-sink. The rectifier is mounted off the side of the board and screwed to the back of the heat-sink. Resoldering this usually cures that problem.

Hello i have a marantz receiver sr7400 fuse


Unplug the unit. Carefully unscrew the screws for the case. Probably 4 screws, 2 on each side of the unit. Remove the cover. Look for the fuses, and replace with exact same type/specs of the faulty fuse. If the fuse, is on a printed circuit board, be careful dislodging the fuse. Hope this helps.

Are all the speakers GOOD and all connected right?
If so then you have at least one blown output amplifier module.
