Kobo Aura blacks

Hello, my Kobo Aura has a problem: in pages with big areas of blacks (say: also when you power off the Kobo), blacks are not visible.

They seem more like a light grey (check the pictures, specially 4.jpg).

The e-reader hasn't got any liquid in it, and I bought about 2 years ago. Can you help me identifying the problem? (screen / battery, and so on)

Thank you

It looks like "ghosting." How often do you have the screen refresh itself?

Thanks for your reply, but changing refresh rate didn't solve the problem.

Instead I solved the problem playing with brightness controls: put to 0%, then to 100%, after that to desired brightness level.

The problem seems to have disappeared... And, as Murphy could say: "If it works, don't ask yourself why"

Very happy to hear you found a solution that worked. Maybe there was some corruption in the memory that you cleared by resetting the brightness level? (I'm just taking a wild guess.)
