The reference YIG oscillator has failed. You will most likely have to send it to IFR for repairs.

That's it?

No possibility of a missing voltage, bad connection, bad driver, PLL or anything else?

What checks have you done so far, have you checked any power supply rails, do you have any service material/schematics? Karl

If you can find a scrap unit with a functional Reference Oscillator you may be able to repair it. These kinds of oscillators are usually temp stabilized, sealed units.
