I'm not sure why the pic is blurry...

same result.... you seeing anything on your pool?  That pic you just sent is from when I turned it on this afternoon.  it worked... but then just quit like 10 minutes later.  Craziest thing.  I didnt overheat, it's in my basement and it's 60 degrees down there.  It got 220v power, just like my other miners. 
The log is crazy though..
pvt_t0 = -40
pvt_vo = 0

is that -40 voltage or 0 voltage or what?  does it list errors like other miners somewhere we can see?
