Started to throw my first build together yesterday - seems like a super nice board (not that I have much experience in this realm, but...). Everything seems to be working nicely with it except for one minor problem: a purple tint to the screen.
The two photos are from the test mode. Both make the screen look like it's got a reddish/purplish filter over it. I've tried swapping LCDs since I got the new 640 x 480 screen as well and the issue remains.

I saw similar posts mentioning yellow or bluish tints that seemed to be less extreme, but I figured I would follow the steps mentioned.
Gently pressing on the CM3 or the FPC connector results in a little bit of fog (backlight, maybe?). Reseating either of them leads to the same result. There do not seem to be any shorts on the pins of the CM3 slot or the FPC connector (zoomed in on my phone's camera to verify).

Update #1
Kite asked for additional photos (good lighting / focus) of the CM3 slot and LCD connections (how they were inserted and the backside).

Update #2
Kite asked me to send the main board back to him. Seems there might be some loose pins that aren't readily visible. Gives me time to figure out if I'm printing or CNC-ing a DMG-clone...
