Please provide a description of the problem

My D435 camera is being recognized as a D430. It was working fine, but suddenly the RGB camera view is not showing up, and it is recognized as a 430. Is this likely a hardware issue?

Hi @seobeomlee If your D435 has been working fine up until now then it is not likely to be a hardware issue related to a detached RGB sensor cable and instead may be a corruption of the camera firmware driver.

In the past, this D430 missing RGB issue has sometimes been resolved by downgrading the firmware to a slightly older version and then re-upgrading it to the same version you were using before (in this case, 5.12.11.0)

thank you for reply so i downgrad firmware version and re updated firmware to same as i used first but it didn't solved my problem and i found that when i reset the hardware error code have occured as follows:

I would expect the Auto Gain Limit error to occur if there was a mismatch between SDK and firmware versions. If you are using SDK 2.42.0 then the installed firmware should be 5.12.11.0. Can you confirm that you are still using SDK 2.42.0 and that firmware 5.12.11.0 was the one that you re-upgraded to please?

[seobeomlee]

yes i changed firmware version to 5.12.11.0 and now error was not occured but still D435 is recognized as D430 i don't know what is the real problem..

[MartyG-RealSense]

These SDK and firmware versions are very old, dating back to 2021. Is there a reason why these old versions are being used, such as the needs of a project, or would you be able to update to the modern versions?

thank you for reply i changed to 2.57.4 and updated firmware to 5.17.0.10 as follows:

but same situation is occured

Thank you. Next, please try resetting your camera's calibration to its factory-new default values in the RealSense Viewer using instructions at #10182 (comment)

If your camera's problem is being caused by a corrupted calibration table inside the camera then this reset process will write a new calibration table to the camera to replace the current one. Calibration table corruption can cause a camera to function incorrectly.

[seobeomlee]

Thank you. I followed that you said and reset the hardware after calibration but it doesn't solved the problem. It is still recognized as D430 camera

Please next try launching the Windows Camera application by typing the word 'camera' into the search box at the bottom of your Windows screen. This should make the Camera app selection button pop up.

When the application is run, if you are on a laptop and the laptop camera is displayed first, click the Change Camera button in the top corner of the Camera app to switch cameras.

With my own D435, the infrared stream is displayed after the first click on this button and the RGB stream is displayed after the second click.

Is your camera's RGB displayable in this app? If it is then it would indicate that there is not a fault with the RGB sensor hardware and the problem may be software related.

[seobeomlee]

unfortunatly it is not displayable in camera app at window thus it means hardware is broken in RGB?

[MartyG-RealSense]

Was your camera purchased within the last 12 months? If so then it will still be within the warranty period and you could contact the retailer that you purchased it from to enquire about a replacement.

If it is older than 12 months and it is a hardware fault with the RGB sensor, there would be nothing that could be done to fix it, unfortunately.
