It may be easier to return the whole unit to Denver, Colorado. Or you can try 1 last thing to try hash with 1 hashing PCB with the PSU, if it works, power it off and add 2nd, and so on. If the PSU is defective or not sending enough power.
But usually, if good beagle bone and a good microSd won't work, then it would be the S4 control PCB to be the cause.

Thank you
we are sorry to hear that, it may be a time for the Control PCB unit to be replaced. Could be the control PCB itself or it could be the beagle bone or combination of both.
However, once in a very while... the MicroSD card physically goes bad. We have seen a few cases where simple MicroSD card replacement from a local store (kingstone or Sony 4GH) took care of the problem.
if another MicroSD card doesn't work, please proceed with the parts replacement via warranty. support @ bitmain . zendesk . com
Thank you
I tried this, it still did not work. I cant connect to it at all, but both LED are Green and the LCD screen is lit up just blank
Hello,
I have tried switching out the sd card as well as the beagle bone black. Neither has worked.
