Hi there,
thanks for your reply. The unit and the psu are working with the two remaining hash boards. When I opened the unit, it was very little dusty, nothing major.
Im waiting for spare parts and will try to repair and run this burned board.

Hi guys,

Im asking for your help. Recently one of my antminers S9 lost hash power on one of the chains. When I came to inspect whats wrong, I have found burned power sockets on of the hashboards. The cable isolation leading to this sockets is also burned. See pictures.

Does anyone have similar experience, is it repairable and what has caused this? Thanks for your opinions.
