Laptop black screen even after replacement

Question

Hello! After my laptop fell it started showing different colors and after some days screen went black.So i have decided to change my laptop screen,then i saw that my laptop screen was broken but also the cable that connected the lcd led screen with my laptop's motherboard was also broken.So i bought both new laptop screen and cable.Both same pins everything.When i installed them both and started the laptop ,screen flashed once then total black.I cant see anything on the screen with flashlight the only difference is that when laptop is powered screen is more black than without power although no graphics or desktop icons.External monitor works perfectly fine.So i'm wondering did i buy bad lcd led screen although it said it was compatible or bad cable that isnt compatible with motherboard and cant transfer the correct data to my lcd led screen in order to show graphics thats why it stays blacks.My laptop model is clevo w650sh.Also at device manager tab screen is shown as Digital flat panel (1024x768@).Below are my new screen and cable.Any help is appreciated!

Did you buy exact replacement parts?  Meaning did you search for the model number that is on the LCD and LCD ribbon and buy exact matching replacements?  Do not go off other peoples recommendations that a screen or cable SHOULD work with your model.  Get the exact model to replace.  If you did, then either the cable or screen are bad, or there is another issue with your motherboard.

well my lcd screen was an au optronics b156xw04 v.5 and i bought from ebay exact replacement but this lcd screen came which they said was compatible with my original lcd screen model so i felt confident.As i told you my screen flashed very fast at first power up of the computer then pitch black.I think maybe the cable isnt compatible with my screen thats why i cant see any graphics on the screen.Maybe the cable cant transfer the data from my motherboard to my screen thats why i want to be sure in what to replace again...

I would definitely look towards the cable.  I have seen the issue you describe before when changing out screens and it can be the cable, screen or a damaged video port on the motherboard.
