KDL40WE663 picture uniformity issue (regularly spaced vertical bands)

Dear all,

Does anyone have an idea what could be the cause of the vertical bands marked in the photo of my TV screen below? They are easily noticeable when viewing normal TV content.

Thanks for your help!

It looks like a hardware issue unfortunately.

I'm currently in contact with the retailer because it's still under guarantee.
