If the Bluetooth or WiFi motherboard is not properly connected or working, the Wii will power on but display nothing.
Remove and reinstall the Bluetooth board.
Check the connectors and pins to ensure they are not damaged or corroded.
Replace the Bluetooth board.
If that doesn’t work, repeat the steps for the WiFi motherboard.
