In case only v2 camera image sensor is broken or damaged (I replaced original v2 camera lens with an M12 mount lens, and some small dirt ended up on the blank image sensor), you could just buy a new imx219 camera module only for less than 12$ (with free shipping to Germany) instead of 25$ for complete v2 camera with board:

I wanted to test that out, and instead having to wait for 30-50 days, I ordered the same "IMX219 Camera Module for the official Raspberry Pi Camera Board V2" from ebay in my country for 17$. By that the imx219 sensor arrived within 4 days from order.
Today I did try the new imx219 sensor. First I used (as always) the 2m flat ribbon cable to connect the v2 camera module with my Pi 3B+. This never did show any issues sofar for me, but I know that 6by9 wrote several times in different threads that longer than 15cm flat ribbon cable is problematic.
First I did unscrew the M12 mount with lens from the v2 board, then unplugged the tiny connector, and finally clicked the new connector into the board. The difference to original imx219 sensor is that the new sensor has 6cm cable length between board and image sensor, while original has less than 1cm (the original connector is on top of new connector plugged into v2 board, I did tape onto the original camera sensor in order to avoid more dust inside):
The preview of mode 7 raspistill -t 0 on HDMI monitor looked really bad, many artefacts I have never seen before. I did record still with this command:
While the preview did not look nice, the camera worked in principle, but to my surprise an all black image got stored:
Code: Select all
raspistill -md 7 -w 640 -h 480 -o tst.md7.2m.jpg
So the question was: Bad imx219 sensor or bad 2m flat ribbon cable?
I replaced the 2m cable with the original 15cm one, and all issues are gone, with same capture command as above:
- If you have a broken imx291 image sensor, but a good v2 camera board, you can get a working v2 camera for 12$ only
- I did screw the M12 mount with lens again on my (only) v2 camera board.
Now I can flip easily between M12 lens imx219 and original lens imx219!
