New dna250 build only working while pluged into USB

[everpresentnoob]

So I just finished my new DNA250 box, and it worked great.  For about 5 mins.  Now it will only work while plugged into a USB cord.  Battery is not working at all.  I have tried different batteries such as my MaxAmps that is in my currently running mod and those dont work either so I know its not the battery.  Not sure what I should check.  Just got the board today in the mail, and now its not working.  I confirmed that the Battery wasnt hooked up reversed.  I just am not sure what else I should check.

Check the fuse, it's behind the USB socket, other side of the board.

I checked the fuse.  after reading through here I saw a number of posts about that.  My fuse is totally white, most I have seen are semi translucent...  Heck I even went so far as to solder a small jumper wire across the fuse.  still nothing.

GOt a reply from the ticket I submitted.  checked a couple things for them and yea, something is wrong on my board.  Sending it in for RMA.  Easiest customer service I have ever dealt with.

got a blown power ctrl ic? that tiny black square with 4pins on each side. i once had this symtom and fixed it with a same ic. the reason y i know where the problem is was because i was testing it without casing at the very moment so that ic just failed with a terrible red flame flash. it was just literally burnt

Got my board back from Evolv.  got it put in a stabwood box I made on my drill press with End Mill bits.  Im happy with it.  should have done a few things differently during the carving, but now I know for the next one.
