I was using my D7100 today taking videos when it suddenly developed this weird horizontal line across all images that it took. The camera never moved or anything. I had it on a stationary tripod for a couple hours and towards the end of the session this line started to pop up. I tried to use several different lens and do a sensor cleaning via the menu system on the camera; however, this did not solve the issue.
I tried to search through the forums for an issue similar to this, but i couldn't find a thread, so please forgive me if this is redundant in any way.
Do you guys think that the sensor is damaged in some way or is something else wrong?
