Can you tell us a bit more. What happened before you noted the issue?

Sadly the backlight within the display has an issue. It’s a bit odd as most of the time we get a stage light effect along the bottom edge where the three or four strings interwoven light or don’t light.

Why did you pop off the display to work on the system? Could you have damaged the defuser elements?

It's a sad story how I decided to replace HDD with an SSD on my own ((

I was extremely careful and attentive, but it still happened (((

@sergiikushnarov - Replacing the display assembly should get you going!

@sergiikushnarov does not look like a backlight issue. Do this, in a darkened room shine a flashlight beam across the dark area. Check if you can see the background when you do that.

A bad backlight would not be illuminated by moving your folder icon etc. into the affected area.

This is either a bad panel or a bad graphics adapter.
