Hello,
A flashing 8 on the display indicates that the Selection and Credit Computer hasn't detected the gripper arm has returned to it's normal rest position over the CD carrier (where the CDs are stored). It can be caused by several factors:
1. Gripper motor switch has been turned off
2. K7 microswitch or actuator is defective
3. Blown fuse in amplifier
4. Defective gripper motor
5. Open latch solenoid coil
6. Defective Selection and Credit Computer
