For reference the laptop model is a Lenovo Ideapad S145-15API Hello, last week my laptop screen started flickering a lot, at first i was afraid it was a GPU problem, but my external monitor image is 100% fine, no problems there, so I discarded that possibility and decided to buy a flat cable. To my surprise replacing the flat cable didn't solve the issue so I'm making this post to ask if this can be an issue on the actual screen before I buy a new one. Here's a video of the problem for reference: https://streamable.com/teiib9 . In the end I also show side by side the external monitor and laptop screen. I ask if this can be a problem in the actual screen because i have never seen something like this as a screen problem. For me it made more sense to be the flat cable, although I'm no expert in laptops or screens. Laptop never took any hit, fall etc. In my head screen problems were always dead pixels, burn in, it would straight up not show anything etc. Also I'm afraid it might be a problem in the flat cable socket in the laptop's motherboard although the appearance of the socket is fine, any help appreciated thanks.

Welcome to the forums, new person! You might try these steps: 1| put your serial number into Lenovo's help page. 2| see if there are any BIOS updates coming soon for your laptop. 3| make sure your operating system is up to date with the newest version. 4| manually reinstall the chipset drivers by downloading them from Lenovo's official site. 5| run DDU to remove your old graphics card drivers, then install the latest ones from Lenovo as an Administrator (right-click the installer and choose Run as Administrator). If the problem only shows up on this laptop, it could be because the display needs replacing. Since you already changed the flat ribbon cable for the screen or that's what I think is wrong, maybe your laptop display just doesn't work anymore. The issue isn't seen on other screens, so your graphics card (iGPU/GPU) probably isn't to blame.
