Can somebody help me please at my iMac Display Black Dot problem?

[flodschi22]

My iMac had a damaged screen so I bought one from Aliexpress Grade A like new the seller said because I didn‘t found one anywhere under 520$, and fixed it myself but it does have this weird black point what do you guys think it is dead pixels or damaged backlight? It looks like I can see the letters when I scroll but the Background is black?!
Thanks for your help guys!

So do you think it is broken?!
Backlight or Pixels?

Most likely pixels.

Looks like something trapped between the backlight defuser and pixel matrix, these panels aren't sealed well and I've had it happen before.

What?

You bought a used item (perhaps without a return policy?).
If the seller was less than honest (looks like he was), you got what you got...

Yeah but this grade he said is the best you can get and like new and I have return policy so I hope it will be good and I will get my money back! But where can I get a display in Europe thats without scratches and damages? Do you have any advice?!
