Wii Black Screen on Start: Troubleshooting Steps from Simple to Advanced

1. Basics (Do First)

• Power Cycle: Unplug AC 30s → Replug → Hold Power 5s (full off) → On.
• Wii Remote: Fresh batteries. Resync: Red Sync button (console front) + Red Sync (remote battery cover).
• Cables: Reseat AV/Component/HDMI (Wii2HDMI) at both ends. Try another TV/input.

2. Software

• Disc: Eject, clean (center→edge, microfiber). Try another game.
• System Update: Settings → Wii System Update (if online).
• Corrupt Save: Data Management → Save Data → Wii → Delete suspect game save.

3. Hardware

• Sensor Bar: Centered above/below TV, unobstructed. Test: Phone camera sees 5 IR dots each side.
• Overheating: Vents clear? Fan spinning? Dust inside? Clean with compressed air.
• GPU/Bluetooth Module Failure: Common on launch Wiis. Black screen = dead GPU or BT module (no remote sync).

4. Advanced / Repair

• Priiloader / BootMii (if hacked): Boot to Homebrew Channel → diagnose.
• Professional Repair: Reball GPU, replace BT module, capacitor swap.
• Replace: Used Wii $30–60. Wii U (plays Wii games + HDMI) $80–120.

Backup saves (SD Card → Data Management) before risky steps.
