Side of my image is brighter than the rest! Sensor issue?

Right side of images are brighter. Don't notice with a busy background.

All of them? This one looks like there is a reflection of light on a window, hence my question. I discarded some pictures because there was a video screen reflecting off the glass and was in my images. Let's start with the simple things, first.

Not shot through a window and no filter. It's in every picture. Noticeable in lighter images. I tried different lenses. still the same.

1. Shoot a shot in RAW (and see if it is visible after using RAW conversion like LR or Photoshop to create a JPG independent of camera processing)
   
2. shoot the shot also as JPG (and see if it is visible)
   

It won't be a lens nor is it the shutter. Both will not cause such a distinct line. One thing to try is a different card on top of Wilt's recommendations. It could be a raw to jpeg conversion issue but it could also be a faulty card. Might try both the SC and CF slots to eliminate a card slot issue.

Was the camera dropped? A light leak along a case seam could make a sharp edged line. To test this hypothesis, take an image with the lens cap on in bright light. See if the image has a bright band in the same area as your images.

And shutter blade issue would be seen as HORIZONTAL artifact...the blades in dSLR travel vertically.

Still noticeable in raw to jpeg in LR. not visible with lens cap on. Tried different cards. Still the same.

"Not visible with a lens cap on" tends to rule out a light leak. Since you are using LightRoom, I'm pretty sure that a bug in creating a JPEG would be noticed by other people. The camera creates a JPEG as well, and people would have noticed such banding as well if it were software related. You can look at the JPEG embedded in the RAW in your camera and see if it shows up there. Look at the image on the back screen and see if it shows up there- you may need to zoom in.

To me, it's starting to look like hardware but I'm not sure what it could be. A software bug in LightRoom or the camera should be noticed by people by now. OTOH, I've seen some bone-headed software changes too.

It's visible on the cameras display also.

OK, the problem may not be in the sensor necessarily, but maybe in the readout circuit that eventually goes to the in-camera preview creation, and to memory card

Maybe the AA filter is not covering the whole sensor.

Well, a part of it. It is a band. I think we agree it is likely hardware, rather than software. Beyond that, we can only guess since we don’t know the circuit arrangement. It doesn’t matter since a whole circuit board needs replacing in my opinion.

The line is too sharp for it to be anything optical. It is clearly something in the circuity. Anything optical would leave a much fuzzier edged line. As it's not a card, reader, cable, or anything external to the camera, i think that the only course would be to return it for servicing.

If it can be seen in camera when reviewing images, and it happens all the time, and it is so well defined a segment of the file, it is almost guaranteed to be a hardware related issue.
