Downward or forward vision sesnor error

​"Since this error appeared after a crash landing, it could be either a calibration issue or physical damage. Here is the recommended workflow to fix it:

1. ​Visual Inspection: Check the two small camera lenses at the bottom. Even a tiny scratch or dirt can cause this error. Clean them with a microfiber cloth.
2. ​DJI Assistant 2 (Consumer Drones Series): This is the most common fix. Connect your drone to a PC/Mac and use the 'Calibration' tool. Follow the on-screen instructions to align the sensors using a patterned screen.
3. ​Internal Check (If Calibration fails): If the calibration gets stuck at 0% or fails, the Flex Cable connecting the Vision Sensor to the Mainboard might be loose or damaged from the impact. You will need to open the shell and re-seat the connector.
4. ​Hardware Replacement: If the above steps don't work, the Vision Sensor Module itself is likely cracked or dead and needs replacement."

If the software calibration fails, you need to proceed with a Hardware Inspection. Based on professional repair experience, follow these logical steps:

1. ​Visual Inspection: Before opening the shell, check if the sensor lenses are clean and the drone body is not physically warped or cracked.
2. ​Internal Inspection: Carefully disassemble the drone. Check if the vision sensor's flex cable has shifted or become loose from its connector due to the crash impact.
3. ​The "Reseat" Test (Try this first): Sometimes the cable is fine but the connection is slightly off. Disconnect the original flex cable, clean the pins/connectors, and plug it back in firmly. Re-assemble and test if the error disappears.
4. ​The "Cable Replacement" Rule: If reseating the original cable doesn't work, try replacing it with a brand-new flex cable. Even if a cable looks perfect to the eye, internal signal lines can be broken. Replacing the cable is much cheaper than replacing the sensor module.
5. ​Sensor Replacement: Only replace the entire sensor module as a last resort if a new cable fails to fix the error.

​ ****** The DJI Mini 2 SE is built with very thin plastic and tiny connectors. Handle everything with extreme care. If you are not experienced in micro-repairs, you might cause more damage while opening the shell.
