To others who have the same or similar questions:

In this case there is no fix as the lines appear mainly over water and near coastlines. The image does not appear to be damaged or corrupted. Results differ based on the color ramps that we are applying in terms of the lines seen on the images. It also seems that the lines are less important than the differences in pixels that you detected in the images. This is due to the sensor information taken by our satellites on that particular day/time and is expected behavior from time to time, the best way is to manually check the images to see whether there are lower values surrounding the pixels in surface reflectance and look for alternate scenes to see if they appear the same.
