DR6000 display "open"

You may need to replace the whole mechanism as i've had quite a few philips and marantz cd recorders with the same mechanism with exactly the same problem. when you press open/close it will display open or close with no sign of life from the player. this turned out to be a faulty laser unit and the PCB which is underneath the mechanism seems to go the same way which i found out later when i replaced the laser unit. the recorder worked for around 5 minutes then the laser started moving erratically but then would work again for 5 minutes after switching it off & on again. i cured the fault by replacing the PCB aswell. hope this helps?
