| Symptom | Likely Cause | Diagnostic Steps | Remedy | |---------|--------------|-------------------|--------| | | Incorrect input pin mapping or missing power rail | 1. Probe VDD with multimeter. 2. Verify I²C address and read ID register. | Re‑wire pins, correct power sequencing, re‑flash firmware. | | Colour distortion (incorrect hue/saturation) | Colour‑space conversion mis‑configuration | Read the COL_SPACE register; check if Y′CbCr→RGB matrix is set for BT.709 vs BT.601. | Set proper matrix; enable automatic colour‑space detection if available. | | Interlaced artefacts | De‑interlacing disabled on an interlaced source | Look at DEINT_MODE register; confirm it is not OFF . | Enable progressive scan mode or select motion‑adaptive de‑interlacing. | | Excessive jitter or dropped frames | Clock source instability or insufficient bandwidth on the bus | Use a spectrum analyzer on the reference clock; monitor I²C/SPI bus load. | Replace oscillator with lower‑jitter part; increase I²C bus speed or switch to SPI. | | Over‑temperature shutdown | Sustained 4K processing without adequate cooling | Check thermal sensor register; verify heatsink attachment. | Add active cooling (fan) or lower the processing resolution. |
