STORZ Camera H3-Z TH100 Maintenance Case

Appearance test: The camera has worn the abrasion marks normally, and the appearance of the cable is more aging.

Fault testing: On -board testing, the black screen and colorful screens flashed alternately, replacing the spare cable test, the screen is normal. The blue focus ring is slightly stuck and can not be processed for the time being.

Reason for failure: Poor contact in the cable internal signal lines causes the black screen and colorful screens to flash alternately.

Maintenance plan: Replace the new cable

1. Appearance testing

The surface of the camera has worn due to daily use, mainly showing slight scratches and abrasions in parts of the shell area. While this affects its appearance integrity to a certain extent, it has not yet caused direct interference with the core function of the camera. At the same time, the cable shows more obvious signs of aging, with varying degrees of hardening, discoloration, and fine cracks. These phenomena suggest that environmental factors during long-term use have contributed to a decline in overall performance. To address both cosmetic and functional issues, professional Storz scope repair is recommended to restore the device to optimal condition.

2. Fault detection

When connecting the camera to the device and conducting the machine test, it was found that the black screen and colorful screens blinked alternately. This unstable display situation seriously affects the normal use of the camera, making the image unclear and preventing continuous presentation. To further investigate the root cause of the fault, the backup cable was replaced for testing. After replacing the cable, the camera screen returned to normal, indicating that the original cable may have had issues. Additionally, when other components of the camera were checked, a slight sticking was observed in the blue focus ring. However, since it has minimal impact on current shooting function, it can be temporarily addressed. For ongoing maintenance and troubleshooting, it is recommended to consult a trusted endoscopy equipment supplier to ensure all components, including cables and optical modules, are properly handled.

3. Analysis of the cause of failure

After detailed observation of the fault phenomenon and the results of the backup cable replacement test, the key to the problem is that the signal line inside the original cable is poor contact. In the long -term use process, the signal line inside the cable may be loose, oxidized or worn by frequent bending, pulling, or. The comprehensive effect of these factors makes the signal line intermittent interruption or interference when transmitting video signals, which in turn causes the faulty performance of the black screen and colorful screen.

4.maintenance plan

Based on the analysis of the above failure, it was decided to implement maintenance measures to replace the new cable. When replacing the cable, you must first remove the original aging cable carefully to avoid damage to other components inside the camera during the disassembly process. Then, select a new cable that is fully matched with the camera model to ensure that the specifications, quality and interface type of its signal line meet the requirements. When connecting new cables, it is necessary to ensure that each interface connection is firm and tight, and the cable is reasonable to carry a reasonable wiring and fixing to prevent it from re -use and pull problems during the subsequent use. After completing the cable replacement, the camera has comprehensive functional testing again, including the stability, clarity, color reduction, and focus function of the screen display to ensure need.
