Blue Spot On The Image

Hello,

I was playing with different ways of installing the polarized filter today and everything was fine until later tonight after coming home. When I turned on the camera to try something else I noticed blue spots on the image in the IDE (see Image_01). Tried different things but nothing seemed to work. Then accidentally I noticed that when I put my thumb on the back of the PCB the spots go away (see Image_02). Did I ruin the PCB and now need a new camera? Any suggestions?

Kind regards,

No, this would be IR light leaking through the back of the PCB. Just add some black tape to the back of the sensor. A manufacturing screw up lead to 2.5K cameras getting out without the sticker on the back of them to block light from the back of the PCB.

Done.

Thank you for the prompt assistance!
