I have a batch 1 that was running fine. I had to go out of town for a few weeks so I turned it off. When I turned it back on today it's getting 50% hardware errors only hashing about 30 MH/s on eco mode i've also tried other modes with more or less the same results. The miner temp on auto is 62C and the MCU temp is 62C.  I actually have 2 and my other one is working just find. What can I do to fix this?
