This looks much more like a hardware failure than a camera setting or exposure mistake. The striped frames and false-color/mostly black images are consistent with a failing image sensor, likely the CCD, or possibly a related sensor connection issue.

Because the corruption appears on the camera’s LCD preview immediately after capture, the memory card is very unlikely to be the cause. A shutter problem can sometimes create banding, but the color corruption points more strongly to the sensor itself. If it happens after several shots, heat may be making the fault show up more often.

The fact that zoom position seems related could mean internal movement or flexing is aggravating an already failing sensor assembly or cable, but it still points to a hardware issue rather than user error.

Practical fix: this generally requires professional repair, typically sensor/CCD replacement or inspection of the sensor connection. There is no menu setting likely to solve it.
