Recently acquired a CR-640 that was not working. First test of the receiver had all lights working, but no sound and no activity on the tuner. Took the cover off and found that there are two fuses on the driver board. One 2a and one 1.5a. There was no 1.5a fuse present. I replaced with correct fuse. Immediately upon power up, the fuse blew. Now I know why it was missing. Any suggestions/ideas on where to start? I do not have schematics for it. Thanks!
