| | Probable Cause | Solution | | :--- | :--- | :--- | | "No Disc" / Disc not spinning | Dirty Laser Lens or Dead Laser Diode. | Clean lens with isopropyl alcohol and a lint-free swab. If the laser does not light up (visible faint red glow), replace the pickup. | | Disc spins but erratic speed | Spindle motor fault or CLV servo error. | Check spindle motor resistance (usually 10-20 ohms). If motor is stiff, replace. Check spindle for wobble. | | Drawer will not open | Belt slip, broken gear tooth, or loading IC failure. | Inspect belt and gears. Check voltage at loading motor pins when Open button is pressed. | | No Audio Output | Mute circuit engaged or Op-Amp failure. | Check the "Mute" transistor circuit near the output jacks. Check +/- 12V power rails. | | Display segments missing | Bad connection on the ribbon cable. | Reseat the ribbon cable between the front display board and the main board. Clean contacts. |
