colored lines on picture

[Zeench]

Hi guys,

sorry my english is not the best, but i think the uploaded picture will tell you what my problem is.

These colored lines pop up on like 90% of the pictures taken.

Does someone have any idea how to solve this issue and what causes it?

Thank you in advance

edit: on the live stream are also lines, but they appear and disappear randomly.

it could be a contact problem.
Check your camera connector to see if it is seated correctly.
