- Picture bounces/wave pattern: Move electrical devices causing interference.
- Power LED ON but no video: Check PC power, video card seating, monitor cable connection, and bent pins. Verify computer operation using the CAPS LOCK key.
- Missing primary colors: Inspect monitor's video cable for bent pins.
