If RAW images are clean and the lines only appear after processing, the detector is fine. This points to:
- Image processing / calibration file issue
- Corrupt or outdated flat-field / gain calibration
- Software artifact, not hardware
What to do:
- Re-run detector gain and offset calibration (full, not quick)
- Clear and reload calibration/processing files
- Check for recent software updates or roll back
- Reboot system cold (power off fully)
If it persists, it’s almost always a software or calibration database problem, not the detector.
