Sony MHCC90
The typical symptoms of a faulty laser unit in CD players include:
Failure to read the CD: The player is unable to read the disc, even if the CD is in good condition. The screen may display an error such as "No Disc" or "Read Error."
Doesn't recognize the CD: When the laser unit fails, the player may not recognize the inserted CD. This can happen even if the disc is properly positioned and has no visible damage.
Skipping or jumping tracks: During playback, the sound may stop suddenly or jump between tracks without apparent reason. This is a sign that the laser is unable to continuously read the tracks correctly.
Difficulty reading recorded or damaged discs: A faulty laser unit may struggle to read recorded discs or those with minor scratches, even though the player should still be able to read these CDs.
Noise or disturbances during reading: The laser unit may make unusual noises, such as "clicks" or "pops," indicating that the unit's motor is trying to position the laser correctly but is failing.
Delay in starting to read: When the laser unit is beginning to fail, the time needed to recognize and start reading the disc may increase.
These symptoms are often caused by a dirty, misaligned, or worn laser lens, which may require the laser unit to be replaced in order to restore the CD player's functionality.
Important:
Before making the purchase, please check the images of the laser and confirm that they match your model.
Some models may have been altered by the manufacturer during production and could have variations.

We will be happy to assist you in choosing the correct laser unit for your equipment.
Final note: Before considering laser replacement, clean the lens with a cotton swab and our Laser Lens Cleaner 10 ml (code F0020).
In most cases, reading failures are caused by dust accumulation on the laser lens.
