Never too old to start
The first thing to check would be the connection cable. Try swapping one out with one in use elsewhere. Also try manipulating the connector (plug) a little side pressure, a little straight in and out and see if a connection is made. Sometimes the connector socket gets loose on the board and has sent me scratching my head until I discovered it. Try the mfr.'s tech support before returning it. Good luck friend.
