Got 7 boards. 1 dead on arrival. Still working out what could be wrong with it. Never powered on. Don't have a multimeter to test until tomorrow

...
I'll be very happy when I sit down tomorrow with some tools and my hardware buddy and figure out what's going on with the dead board!
I also have a dead board. The fuse is ok but there is a short on the board. Cryptx doesn't answer to my emails. Has anybody an idea what I can do now?
Similar situation here. One of my Bitburner Fury boards died shortly after it began hashing. It didn't even last 2 days. Maybe 36 hours. Now it is dead, no lights, no nothing. Just dead.
I left a PM for cryptx, but so far, no response.
I followed up with an email to
info@asic-hardware.com, and I await a response.
By the way, I purchased these boards before the price was dropped to 1.5 BTC.
Let's just say I paid almost double that. Last week. I'm not pleased at all.
Cryptx -- I would appreciate a response. Thanks.
