Olympus CV-190
Olympus · Model CV-190
• Dual Focus - A unique OLYMPUS innovation based upon an innovative two-stage optical system enables the user to switch between two focus settings. With the simple push of a button, the desired observation mode can be selected: “near mode” featuring ground-breaking resolving power for close mucosal observation or “normal mode” for normal observation. Even in “normal mode”, EVIS EXERA III endoscopes feature an advanced level of resolving power compared to previous generations. • Brighter and higher contrast Narrow Band Imaging - NBI in EVIS EXERA III offers a significantly increased viewable distance compared to previous generations. The improved contrast combined with this increased brightness means that NBI opens new possibilities in assisting you in lesion detection and characterisation. • Pre-freeze - An exciting new feature, pre-freeze automatically selects the sharpest image when the image is frozen by the user. • Improved image processing - New and improved image processing delivers outstanding image quality thanks to reduced noise, reduced halation and improved colour contrast. The result: the optimum in image quality • Waterproof One-touch Connector - The new one-touch Connector enables a one-step connection to the light source and does not require a separate video cable for connection to the video processor. This saves time during procedure setup and dismantling. • Variety of signal output options - A whole range of signal output options are available dependent upon the monitor attached to the CV-190, enabling you to achieve the optimum image for the installed infrastructure. 16:9 and 16:10 format is available for HD monitors.
Key tips
- ·A failed leak test means the scope does not get reprocessed or used - send it for repair, full stop.
- ·A shortened reprocessing cycle is a real infection-control failure, not a minor deviation - follow AAMI ST91 exactly.
- ·Track light-source lamp-hours against the manufacturer's limit rather than running to failure.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Image sensor / CCD fault
HighSymptoms: No image, color shift, or visible artifacts.
Root cause: Image sensor or its driver board aging.
Camera cable / connector wear
MediumSymptoms: Intermittent signal or no image at the tower.
Root cause: Cable flex fatigue or connector pin wear.
Coupler / lens fault
MediumSymptoms: Blurry, dark, or off-center image.
Root cause: Coupler or lens element misalignment/damage.
White balance / calibration fault
LowSymptoms: Color inaccuracy that won't correct on white-balance.
Root cause: Calibration drift or button/sensor fault.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Leak testing before each reprocessing cycle
- ·Scope reprocessing per AAMI ST91
- ·Light source lamp-hour tracking
- ·Annual full PM
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Image sensor / CCD fault
- Confirm the presentation - typically no image, color shift, or visible artifacts.
- Check the most likely cause first: image sensor or its driver board aging.
- Inspect the affected subsystem against the manufacturer's inspection checklist.
- If the fault is confirmed and not a field adjustment, service or replace the camera head / sensor assembly per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: Camera cable / connector wear
- Confirm the presentation - typically intermittent signal or no image at the tower.
- Check the most likely cause first: cable flex fatigue or connector pin wear.
