Hello every experts
I have two not working hashing boards with different version and different behavior when energized.
The first and the original one v1.5

The second that i have is v1.7
http://imgur.com/a/Y0Ob6 and when powered sometimes causes a short hashing peak too but also does not work and does not consume energy.
Since it does not seem to have any damaged component, will it be that by introducing a LDO module (5v to 3.3v not sure) i will solve the problem?
Thanks in advance for any help for this problem because the factory stopped manufacturing these parts
and I can not find any point of sale
