I was just trying to get my a590 to autoboot when all of the sudden it died. I finally realized that the RF shield on the A590 was shorting out on the trace coming from the powers supply connector! I was wondering what that white powder was that I had wiped of the the PCB over the powers supply trace.... It was from the arcing between the RF shield and the power supply. The powder built up, made an insulator, I wiped it away, then it shorted out again. The RF shield was in the proper place, but it just so happens that it runs over a couple of traces from the power supply. I wonder if any one else has had this happen? Jason
