Wii and Wii U disc read errors ('Unable to read the disc', error 150-1031/150-2031) Disc read errors on the Wii and Wii U are usually caused by a dirty or scratched disc, or a worn laser in the drive. Rule out the disc, positioning and software first; on the Wii, most persistent disc read errors are fixed by replacing the laser (lens) assembly inside the drive. by CircuitScope research team · 09 Oct 2026 · 2
