Unable to calibrate 8mp-n-75 camera also calibration wizard will not pickup on dot matrix

What does the feed from the camera look like if you just view it using the Windows Camera app?

I’ve seen two other cases where the metal lens housing was not properly attached to the board, causing the auto-focus to fail, and before long the housing fell off completely, as the soldering is partially responsible for holding it in place. See if yours is loose at all loose. Regardless, we’ll replace it. It shouldn’t look like this.
