S9 board component specifications?

[aherr]

Hello,
I have an Antminer S9. Few days ago the second hash board died (no red LED). After reading some posts here and watching some videos at youtube I got the feeling that a repair could be possible. I have a friend with good knowledge on electronics and the required tools. My only question is: does someone have the specifications of all components (capacitors, resistors ...) that are on soldered on such a board? This way I could check and replace the component that failed.
In one of the youtube videos the guys says that the specifications could be downloaded from bitmain, but I didn't find anything...
Any help would be appreciated.
