Topic: Antminer S3 Slowed to Crawl - One Bank ASICs Working, Others 'dead' (Read 627 times)

Update: after looking closely, there was a broken solder joint on one of the inductors on one blade. That blade now works completely. Other board still half-down.

Just bought a used Antminer S3 a couple days ago, set it up, and it was running quite well. Woke up this morning to a low rate alert on a worker. One whole blade was out, disappeared completely from the status page even. Took it apart, cleaned the hell out of the nasty heatsinks, and fired it back up. Both blades now show up, but ASIC status shows "--------" on three whole banks, with the last showing "oooooooo".
Ideas?
PSU output is testing at 11.85V (under current load) which is within ATX standards, but I'm not sure how sensitive these things are to voltage drops, since I've been running a handful of those little U3's before now.
Additional info: The half-operating blade is running at around 38 degrees, the completely inop one at around 44 degrees. Just a bit weird to me.
