[3dem] Camera CMOS malfunction

[David LIEBL]

Dear all,
Has anyone experienced similar CMOS malfunction/damage on TEM camera or could anyone tell what could have caused this kind of malfunction?
Attached is one illustrative image (flat field-corrected) plus dark frame image (uncorrected) for a reference. Both images were saved as 8-bit TIFFs (4K) and binned 4 (to reduce file size for email).
Note the two vertical stripes - they look exactly like motion blur filter applied at zero angle with distance of 10 pixel (simulated in Photoshop).
Any suggestions?
Camera status description is also attached.

Thank you for advice,
David
