Disc drive laser failure
Disc reading failure is the dominant Saturn fault. The CD laser assembly degrades over time — early symptoms include discs that require multiple attempts to load, audio CDs that skip, or games that crash from read errors mid-play. Progressive degradation leads to complete inability to read discs. Laser potentiometer adjustment can restore a marginal laser temporarily; replacement or ODE installation is required for lasers that have degraded past adjustment. The Saturn's disc drive mechanism varies between early and later production models — describe the model number on the serial number sticker in the intake form.
