I just got a Harman Kardon DVD 5 DVD player today in the mail. I plugged it in, switched on the main toggle power button, and the on/standby switch turned amber in color-just what it is supposed to do. However, it will not respond if I press the on/standby button or if I try to use the remote to turn it on (bring it out of standby). Is there some quirk with HK stuff I am missing or is this thing a dud? Thanks!
