If your monitor is completely dead, even with known-good cables and power, it's likely a failed internal power supply. Open the monitor (carefully) and check for blown capacitors (bulging/leaking tops), burnt components, or fuse issues. Replace faulty parts if skilled; otherwise, seek professional repair to avoid electrical hazards.
