My OnePlus QLED TV developed vertical lines due to moisture, which affected viewing. Normally, hiring a technician for this repair would cost ₹25,000–30,000. I carefully applied WD-40 to the affected connectors, and after drying, the vertical lines disappeared and the screen was fully restored. This project demonstrates a simple, effective, and cost-saving repair using WD-40 for electronics maintenance.
