Yamaha CR-840 FM Problem

I have a yamaha cr-840, it was working fine and then one day the FM just fizzled. The tuning indicator do not move, the stereo, distance lights above the tuning knob are inoperative. No noise at all when tuner is selected. Seems to be dead on the FM side. I opened it up and looked for fuses. I found 3 fuses on the power supply side, all checked out good. Receiver works fine on other inputs, so the amp side seems to be fine.

I found an operators manual on the intenet to download, the schematic is hard to read, not very clear.

Any suggestions?
Anywhere I can get a better schematic, maybe download a service manual?
Are there more than 3 fuses?
