Hi all. I'm getting problem with the drawer of my NAD C521BEE player. Instead of the normal just one quick press on the "open" button to open the drawer, occasionally I have to keep on pressing the button for maybe 5 or more seconds before the draw comes out. And at times, have to do this the second time to open it. Moreover, the drawer sometimes closes half-way and comes out again, and has to be closed by pressing the "open" button again. I have replaced the rubber belt and also cleaned with electronic cleaner the "open" button. Also, the socket linking the control PCB to the main PCB circuit board has been cleaned the same way. However, problem still cannot be fixed. Grateful for solutions to the problem. Thanks.
