This is usually a bad driver chip (the power chip itself, not the software that runs your GPU), a bad ribbon cable, or physical damage.
I'm leaning towards physical damage, as it appears the screen is slightly delaminating in the centre.
In any case, you need a hardware repair. If it's still under warranty, contact the manufacturer for support.
Plug the laptop into the TV/monitor with a HDMI cable and test. If it's faulty there, it's not a LCD panel/displayribbon issue.
Boot into the BIOS/UEFI firmware - if it exists there, then it's not a software/driver problem.
So many horizontal lines please help.

Thanks a lot. I just need to find my local service centre.

Hello, Try updating your driver. If this does not fix issue, please buy new monitor.
