I really disappointed with your service to repair, it is even second time for me from S19 PSU. actually same and more. ;(
1. control board
- Not flashed right version of the image, I tried to update by SD, flicking is over 1hour. could not be updated.
2. Hashboard, checked by other S17e's control board.
- not fixed the original problem, 0 asic found.
- Mixed hashboard, I sent two defected hashboards to repair, the version is v1.3, but I checked what I received from bitmain repair center, its version is v1.4. so surely not match the ID between three hashboard, stopped working. at least you should make a same ID on the board.
Thanks for your very kindly service, BITMAIN. you don't want to ask any request after sales.
