Left LCD has a dark rectangle

The backlight is working fine. But where there pixel matrix is, the left LCD is dark and the text is only visible at an angle. I think that is typically a bias problem. Any one else seen this? Anything I can try to fix it?

It looks to be a wiring problem. It is fairly intermittent. Right now it is bad, but if I put light pressure on the top surface it sometimes goes back to normal.

Hey @joey. If you lightly shake the mod do you have the same effect as pressing the displays? It could be a bad function of the display itself or, as you said, a wiring connection problem. Would you be willing to open your mod?
