Any luck with Bitmain helping you? I had one explode, looks like wpgdeez'z below. Except it was the cap under the 12V+ header.(One farthest left in the below picture) Funny thing to is, it was the same side of the miner. IE, the side opposite the control board.
Still haven't found the cap cover. Sure did give off a nice spray of sparks.
Heres what you don't want your cap to look like ...

They gave me an RMA number for their account with UPS and UPS didn't know what I was talking about. I haven't bothered fixing it, maybe i'll get someone to solder on a new cap and see if it will hash again. Not sure what caused the CAP to pop, I would think some other underlying issue.
