Hi.
My 533mc pro has weird pattern in every flat frame.
Here's a link for fits files. Plaease have a look,

In all of my stretched flat frames, a line that crosses the screen diagonally appears, and it always appears even after changing and testing the light source of the flat.
It did not appear on other cameras in the same optical system. No filter is combined, and the higher the gain value, the fades the pattern.
I've done everything I can, but it always appears. (AR cleaning, changing the flat light source, different temperatures, different gain, different offset, etc.)
I doubt my camera is defective.
Is it normal for this pattern to appear? I want to hear your opinions
