No connection

No heartbeat, no A, B, C lights, the port is being recognized. Reset doesn’t do anything. This a brand new board that hasn’t been connected via battery. It just hasn’t worked from the beginning. I even took it apart to look at all the components and nothing is out of place or damaged. I have two other apm’s and never had this issue. Should I send it back? Thank you

Are you able to flash firmware?

No, I cant connect so not able to up load new FW. Here’s a vid about it … lr1K0PIi7w
