Wii Error: "An Error Has Occurred. Turn Off Power." Fixes

This generic crash screen (black background, white text) indicates a **system crash / exception**. Common causes & fixes:

1. Disc Read Failure (Most Common)

• Dirty/scratched disc → Clean radially (microfiber + IPA).
• Failing laser / drive motor → See related guide for buzzing drive.
• Dual-layer disc (Brawl, Metroid Prime Trilogy, Xenoblade) — laser struggles. Clean lens.

2. Corrupted Save / System Data

• Settings → Data Management → Save Data → Wii / SD Card → Delete corrupt file (red ? icon).
• System Menu corruption → Requires **Priiloader** / **BootMii** (homebrew) to fix.

3. Homebrew / Mod Issues

• Bad WAD install (banner brick).
• Incompatible cIOS / IOS version.
• Theme brick (bad .csm).
• **Fix:** Hold Reset at boot → Priiloader menu → Load Homebrew Channel → Fix.

4. Hardware Fault

• GPU/CPU solder fracture (overheat) — "GPU artifacting" before crash.
• Bluetooth module failure (Wiimote won't sync, error on boot).
• Wi-Fi module failure.
• Capacitor plague (early launch units).

Troubleshooting Order

1. Eject disc. Boot without disc. Works? → Disc/Drive issue.
2. Remove SD Card. Boot. Works? → Corrupt channel/save on SD.
3. Sync Wii Remote (red buttons). Fails? → Bluetooth module.
4. Boot to **Priiloader** (Hold Reset on power). If loads → NAND OK. Fix via Homebrew.
5. No Priiloader / BootMii? **No software fix.** Hardware repair or replace.
