I had a similar (but probably worse) failure of one of my Tbolt's. When I went back to turn it back on, there was no response on the software. Everything was a 'question'. The 10 MHz output was there but it never 'locked' as compared to my other GPSDO's (although it was EXTREMELY close) and there was no 1 PPS output. I suspect a power issue to the processor and GPS receiver but I have not had a chance to track it down so far. I did open the unit and 'sniffed around' but I did not see any obvious issue. My plan is to set up an operating Tbolt and the 'dead' unit, side by side, and start tracing levels and voltages.
I would be very interested in anything you discover.

While re-arrangement of the shack, it's been idle for 3 weeks, Tbolt turned off. After turning the unit on and letting it settle some 2 hour, I connected the monitor program and found the following that I can not explain and correct:- * All SV and AMU have question marks * Product info has questions marks * the ability to see tracking status is blank. When last used, some 2 months ago to show a friend, the relevant display data came up, no issues. Further more, position, critical and minor alarms are green, disciplining status section such as DAC voltage DAC value mode and even it's 10MHz out etc etc is fine compared to my trusty Rubidium standard. Has any one seen this before and is there a setting that may have inhibited this feature? I have a screen shot, however it may be to large to attach, so let me know if this will help, I will be glad to forward it to some one with much more knowledge. Thank you in advance.
