i got the errror when run test 27
33: CC clamp pos error.
The clamper cannot go to the desired position. The reason may be that it is locked
or that there it is an error on PCB22, clamper position, or that the motor driver is
defective.
Sometimes The cd tray bump forward from position 1 and than restart into standby.
Sometimes its just stay at cd 1, and if i press ect cd 5 the display says cd5 and than the BS9000 goes into standby after some 15-25 sec.
How can i fix this problem?
