    See if the same lines appear on a TV screen via HDMI. If not, then your LCD video ribbon cable connectors probably need to be reseated at the base of the laptop screen & mainboard due to corrosion buildup that happens when not used for a long period of time. The screen bezel and keyboard usually need to be removed to access the connectors. Jack E/NJ

    Okay forgot to post an update but reseating the screen connectors fixed the issue plus my main laptop is now fixed and the acer’s hdd has died after like 8 years of wear and tear right after I got my main laptop back.

    Congrats. Thanks for reporting back. You might still be able to get  stuff off the dead drive through an HDD-2-USB port adapter. So don't toss it yet. Jack E/NJ
