Is the flickering screen on the laptop and monitor 2 working?

I have my second monitor on the laptop and I see everything as normal, but on the laptop screen itself there's always an on / off of the screen. Can someone help me please?

In principle, is this always or only when the monitor is on?

It was suddenly like that and the laptop screen flickers all the time, the second monitor works great. I read that it could be due to the cables in the laptop?

Yes there are so wide ribbon cables on it so that you can open the notebook and if the contact is no longer 100% then such effects come.

Maybe it helps if you reinsert it and fasten it again with this clip, but you need know-how like a technician.

Usually, however, it takes some time before such problems arise, has he already had a few years on his back?
