I've had 3 DL3's for about a month.  In the last couple weeks when I power them up, one of the servers doesn't power up.  The moving light part powers on and goes thru it's normal calibration just no server, screen or CMA contact.  I have to go manually turn it on(holding the top and bottom buttons).  It works fine once I go up and turn it on.  It was turning on before correctly.  Any suggestions?
Thanks in advance,
Richard
