Even a repair at dayun is on payment and that makes the ROI get to a unreachable amount of time
I could also consider a paid repair even if the miner is brand new supposed to be in warranty, but the point is that I still havent found the REAL DaYun manufacturer contact! Do you know it (verified)?
And if you have an idea how to repair the main board, could you suggest me a way (I have some electronic skills)?
Ive just visually inspected all components and tested capacitors and resistors without finding anything burned out.
I could also consider to ship you the whole device, where are you located?
Thanks!
