When no sound output in the CD function, you can not listen to music reading data
from a CD disc if the servo motors in MD don’t work. This step is for checking the
SLED MOTOR among them.

4-2-1. Solution
Please check and replace IC407, IC408 on MAIN board.
4-2-2. How to troubleshoot (Countermeasure)
1) Check the SLDO signal from Pin15 of IC407.
If no signal, check 3.3V(RF) and X402.
2) Check the SLED+ & SLED-from IC408 to CN405 for driving SPinDLE motor. It is about 2.9 Vp-p.
If no signal, check +1.8V and +5V for IC408.
3) Check if the FFC cable is solidly connected between CN405 and MD.
4) Check the MD.
If the sled motor is sort-circuit or has any trouble, it can not move the pickup module.
Please check the function after changing another MD.
