<font color='#000000'>Hi there - this is a B Stock 5 disc changer I just got today from Dakmart, an authorized online Denon dealer. I took the 2 red screws out from the bottom just like it says and plugged it in. Just a few seconds after turning it on, it makes a small whirring noise and then an ERR message comes on the display. No amount of pushing buttons etc changes anything. The tray just won't open. I even put the screws back in and took them out a couple of times but no dice. This is really frustrating. Any helps or tips on getting this straightened out would sure be appreciated. Luckily there's a warranty on this, but I'd hate to send it right back! Thanx</font>
