Hello, Please avoid moving the sledge by hand, as doing so can cause the motor to feed back and potentially damage the drive transistors. The sledge should not move when the unit is powered off, unless it was turned off while attempting to change a CD. No Movement: If the sledge is not moving at all, the drive transistors may be blown. Check TR18, TR19, TR20, and TR21. PCB35 Motor control. Clamping Issues: These are often caused by dust buildup on the worm gear for the clamper. If left unaddressed, this can eventually damage the motor. Possible User Repairs "Cleaning Required" Message: This message appears when the CD player cannot detect the door. The sledge will usually begin to move after some time, albeit slowly. Clean the black sensor windows on either side of the CD player. Reboots After CD Selection: This may indicate that the safety laser lens needs cleaning. Clean the two small clear lenses located on either side of the CD player.
