Hello my lcd was broken on my screen so I bought a replacement screen I replaced everything and everything works but the screen is just black I can hear the sound effects on the screen and everything any help?

Try reseating the connections to the display and see if anything changes. If nothing changes, try your old screen. If your old screen works, it might just be a defective new screen. However, if your old screen still does not work, it might need motherboard work. Let me know if you would like to send it in for repair anywhere as I know a few places that would be good. I hope this helps!
