[time-nuts] Trimble Thunderbolt CPR?

Trimble Thunderbolt CPR?  

An Ebay purchased Trimble Thunderbolt arrived DOA, it has no rs-232 output 
and I should also check the 10 MHz output soon. I'd like to have an initial 
look at a diagram to see if there are any "user serviceable parts" on board. 

Initial web searching suggests the schematic is not easily located. 

Would anyone have a source (even if I have to pay for it) of a diagram and/or 
any initial suggestions to trouble shoot an appearing to be dead Thunderbolt. 

I have a working Thunderbolt available for relative comparisons, sitting right next 
to the DOA unit. 

Again, thank you in advance for your replies. 

regards,
