It would be more likely that it's already torn, could be at a point where the way the cable is bent affects how well the broken lines let the signal through, but it wouldn't be something that's easier and cheaper to repair than replacing the entire screen. If that was the case you would likely be able to notice significant changes in what's displayed on the screen when moving the lid.
Looking at the pictures you attached now, the trimmers are most likely not actually the issue or at least only the flickering/interlacing part of it can be solved like this, from those pictures and especially the first one, it looks more like something was spilled on the screen. When those trimmers are not correctly adjusted, usually the colors look much more washed out but a white would still be a white, together with the flickering effect.
