NAD C541 Tray Won't Open

I'm no NAD guru, but you should be able to take the top cover off by removing the screws on the sides (there maybe a couple on the rear of the unit holding the top on as well) which will allow you to remove the cd, and see if something is jammed-up. You'll want to keep the unit level until you get the cd out, if possible. Sometimes the rubber drive belt that opens and retracts the cd drawer stretches or breaks- if you're handy you can likely replace it yourself.

Thanks very much for the reply. Any other thoughts?

If the display is reading "open", I would ever so gently try and see if the tray will slide out by using a tool in the small openings to see if it will just slide out. If you press close, does the reading change? If so, it sounds like the belt or other mechanism actually doing the opening and closing has broken. Of course, if it is still under warranty, I wouldn't fool with it and just bring it in for servicing.
