Hello, So after many months with no problems, all of a sudden my Spark will no longer beep when I hold in the power button, my RC and tablet do not "see" the Spark and so can't connect. I tried using DJI Assistant with the Spark linked directly to my computer with a cable, but even then the computer never "sees" the Spark. I have talked with DJI and they say I need to send it in to fix it. But I am in Brazil so sending it for repair is going to be a pain (apparently only one authorized store in Chile for all of South America). I could send it to the states with a friend, but he doesn't return until December. So, I want to see if I can fix it. I imagine that it will be a very easy fix (though may be wrong) and wonder if any of you have an idea of how to open up the Spark to fix this problem. Any ideas?
