Good day to everyone! I encountered an issue with the drive of a CD Discman, and I think this story might be useful to many fans of these players. I’d like to share the repair process of a CD Discman from the 2000s by Welltech.
I bought it for a few euros as a non-working unit and brought it home. Upon inspection, I cleaned the corroded contact in the battery compartment, inserted the batteries, and the Discman started working. However, it didn’t read discs on the first try.
I cleaned the lens with alcohol and lubricated the motor, the rails, and the worm gear. After that, the player started reading discs on the first attempt, but almost every time I launched a disc, it was accompanied by a rhythmic, loud knocking sound that lasted for a few seconds. After the noise stopped, the disc would play without any problems.
Since I had never repaired CD players before, it took me a while to figure out why the drive was making that noise. The issue turned out to be that the laser block, having moved all the way to the motor, wouldn’t stop moving, and the worm gear kept skipping in the drive’s fixing bracket.
After checking the limit switch for the laser movement, I realized it was to blame. I sprayed alcohol into the switch and lightly lubricated the button with a cotton swab. After that, the knocking sound stopped completely.
Thank you to everyone reading my story. I hope it helps someone. I wish everyone peace!!!
