E4402B Tracking Generator Fault

We had an issue a while back where one of our guys was using the output of the tracking generator to drive a small amplifier and somehow damaged it: Previous Forum Post 

Anyway, we have been using the SA without issue since then but of course the tracking generator still does not work. 

I finally went through and verified the RF and TG sections following the service manual and everything checks out okay with the exception of the TG RF output. I cannot measure anything from the RF output but I can obtain an output if I hit the "Tracking Peak" button but the signal is a mere -85dBm.

All the LO signals are within spec, and the TG attenuator works as well. 

Am I missing something with the configuration or is the TG hooped?
