Welcome - I look forward to reading more about the recording scene in Bolivia if you have time to tell us.

My guess is that static or maybe a microfibre was shorting something in your board?

What should be static.?
The truth is not what happens to my DM, as shown in the video with a single blow, the sound came back, maybe it was just the offline bus, but as I said we connect ..... but nothing but hand through the Master components and ready .. but .. before disassembly, with a blow sertero, returning sound, ooops ...... I do not know. but thanks for the time .... if you need more information ... please let me know .... I will go with pleasure all the missing information ... thanks

Greetings!
before removing the DM test I did all I know, Ram reset and the test you indicate Fiber, but the latter did not miss any, all approved. Friends ...., will have been a lack of grounding in the DM? ......
