Are you sure the YIG is dead? How do you know? I suggest you don't adjust anything until you know what the problem is.
My method of troubleshooting is to go through the adjustments procedure but WITHOUT ADJUSTING ANYTHING. Anything way off indicates the?problem area. Often a failure in a closed loop.

The voltages are OK but there is NO outut from the YIG. I see the 3.8 GHz signal (+10dbm) from the cavity oscillator but absolutely nothing from the YTO.? If it's no the YTO what else could it be?
