    What do the grounds look like? Thanks
    It depends. Could just a tab that hits another metallic surface.
    Could be a wire or the ground is part of the ribbon cable (common).

    V+ is the power (battery positive), ground is the battery negative connection in simple terms.
    There any tear down vids for this? Probably.
    They can be helpful.

    Mustang 7747 could be right and the new display is defective. Did the old display work?
    Try that if so and see it it fires up.

    Best to work on a earth grounded ESD mat with wrist strap. In a pinch use a bare wood surface.
    Either way bring the relative humidity up to 60% to help dissipate static. If it's dry you can boil water in the room to raise it.

    Quick update. So I ordered a new back cover brand new and it's still doing the exact same thing. Neither screen is working. How can it be that I can replace every single part in this tablet and it still doesn't work? Any idea how much it would cost to have an engineer look at the tablet just to tell me what is wrong with it? I'm determined to get it working now.

    Is the power supply good?
