Troubleshooting the Whiteout
Symptoms
- The screen initially works but becomes distorted with waves.
- Clarity deteriorates, eventually turning completely white.

Potential Causes
- Loose Screen Connection: A disconnected screen cable can cause a permanent white display.

- Consult a Professional: Diagnosing and repairing blown fuses or power supply issues often require professional expertise.
