Beaglebone Black Died

I had been using by BBB for 3 or 4 days straight when it suddenly died on me.
I can’t power it on at all using any of the normal methods (USB, Power or Cape connections)
Any ideas?
Have tried to raise an RMA but email gets sent back after 3 or 4 days


What RMA address are you using. I have not seen any RMAs from you.
