Micro 4/3 Marks on gh4 footage

Is there anyone who knows what these marks are on 4K footage and some still shots? There is a long line that looks like a dirt line from top to bottom just to the right of the center screen which shows up especially on color sections of the shot but disappears where the footage is very light or washed out. This line is not dust spots or banding that I am talking about. It is a very faint long line but distinct when viewed in photoshop or premiere pro. I am able to touch it up in photoshop for stills but the footage is ruined every time. What is this? Look at the zoomed shot attached.

Looks like a column of bad pixels...I doubt cleaning will have any effect.

Does the camera have a "pixel refresh" function?

I agree that cleaning would most likely do nothing. It definitely looks like a line of messed up pixels. As Luke stated, I would try doing some kind of pixel mapping function, if that camera has it and see if that does not fix it.

My guess, though, is that this is something that would need sent in for repair.

Well - Update on the Pixel Refresh function:
It did not work (unfortunately) I tried it a couple of times.
It looks like a repair shop will be visited.
This is the mystery pixel line after the pixel refresh.

Ok Guys, Now I have the solution to broadcast.
The sensor was "broken" basically - a defective sensor.
The entire M-Box which consists of the sensor, and the encasement with front lens attachment and 4 ribbons on the inside, had to be replaced.
I would say that this piece is half of the camera.
It costs $850.00.
I know! That is shocking!
It was either that or scrap the camera.

Wow... Expensive repair. But less than a replacement camera.
