Vertical lines, only on dark parts screen. Old screen working good.

Hello,

I purchased cheap screen from aliexpress.

It works, but it make vertical lines when on the screen is nothing very bright.

If whole screen is black, it slowly comes to gray/white, but if some bright pixels are in the way, line disappear.

When i switch back to old screen, it works fine so the problem is in the screen.

But why is this happening? Is it caused by bad grounding or something else?

You can see in video what it doing: https://www.youtube.com/watch?v=JlnW7GGe...

If you've tested the old display, and everything is fine there. Then it can only be the new display. See if you can get an exchange from the supplier. Or better yet. Get a refund and get a quality display, from iFixit

the likelihood is dirty or improper connections, remove the screen and ensure that the connections are clean and none of the pins are bent or broke, reconnect the screen, if this problem is still persistent then you are dealing with a faulty LCD.

id just replace the LCD, the cost of an screen is relatively cheap, and its a simple job to do.
