It is a denon 3 CD player and I broke it by putting CDs in when there were already CDs in there :0( now the bottom drawer of 3 won't open at all and the two others keep popping in and out until you turn the power off
I have experenced this problem before. What you have to do is insert a thin screwdriver (two maybe required) into the Disc Drive(s) and fiddle around with it, while continually pressing eject
