HELP

Just received my Antminer S4 and having a difficult time setting it up. When turning the machine on it whirls at full speed/noise, but never settles down. The LCD screen is bright but never displays any text. Anyone know what the issue is?

This occurs whether directly plugged into my computer, or plugged into a Netgear N300 wifi to Ethernet adapter. I unscrewed the lid, and all of the cables appear to be plugged in properly.

Popped the SD Card out, and then pushed it back in. Miner worked! Stable after adding CK's cgminer mod. Running 1.82GH at (hopefully) 1060W as suggested on BtcGuild. Thanks for the help on this thread!

Congrats. The shipping gods have not been kind to S4s, although all three of mine worked out of the box. One had a bit of scratched paint.

Mind posting the Freq. and Voltage your using and/or a link to the article you read?
