I have gone through all the un-bricking procedures with no luck. There has never been any connector or snap on IO changes while powered up and it was in a secured area where no casual access was permitted. Environmental control is automated, but also monitored and trended. If it were to fail we would be notified immediately. It looks like I just got stuck with a lemon that i can't turn into lemonade. 🤕 When examining the circuit board I found U601 (RFP 56512) to be too hot to touch. It looks like it may supply power to U500 FPGA (Lattice LFE2-6E 7FN256C-6I) as that IC is also very hot. I removed U601 and then U500 did not get hot, but probably because it now had no voltage source. I suppose I could replace both of those ICs and hope it doesn't go beyond them. Would be really helpful to have a schematic, but I seriously doubt that would be available. So at this point I have nothing to lose replacing components as it certainly is not covered under warranty . It may take a ride in my reflow oven as a last ditch attempt at revival.

I was afraid of that. I'll try the un-bricking procedures and see what happens. I guess at very least I now have a spare display for the other 3 v700's I have running.

Has anyone had a problem with the V700 having a very short MTBF? I bought one in 2017 for a project that was mothballed for a couple years, so the v700 sat in its box unopened. Two years later the project was picked up and the unit was placed into service, in an environmentally controlled computer room with whole room UPS protection. The system ran fine until about 4 months ago when it went completely dead. it was still drawing power, as the back of the unit was warm, but no display, no Ethernet, and no USB communication. Unitronics supports response to my support request was this: "Thanks for reaching out to Unitronics Support. All Unitronics units come with a 2 year warranty. Unitronics does not offer parts or repairs. " Their only recommendation was to contact sales to purchase a new unit. Has anyone else experienced a short MTBF on a unit that was not exposed to a harmful environment? Is it assumed then that the unit self-degrades while still in the box? I would have thought that Unitronics would have stood by their products more than this. Guess not!
