94 Infiniti Factory Bose System Dead

The Radio is complete dead. No Audio Out or illumination from the face plate
after the Power switch is pressed.

Checked 1 Audio 10amp Fuse OK & 2 Bose Speaker 20 amp Fuses - OK All located
in the left kick panel fuse box.

Any other possible Fuses or Relays that need to be checked??

Any help would be greatly appreciated . Thanks Jim
