Mark Levinson 390S reprogramming

Thanks for your answer,but it's not reading the cd.

I moved the player with the lock screw , when i removed the screw the player is reading the cd's but as a data only without music.

I got the following procedure from ML to reset the No. 390S:

1) Turn unit OFF (not standby).
2) Press and hold the front panel PAUSE button.
3) Continue holding PAUSE button while turning power ON.
4) The unit will display START UP, CODE XXXX, NEW DATA, DEFAULTS on the front panel display. Release the PAUSE button when the display stops changing.
