@delarue64692 a cracked screen can't be fixed. We can't see what you see but going by your description, this is a mechanical damage. There is no repair. You will have to try and find a screen for it.
Remove the back cover and check the label. It should tell you who made it and the exact model for that. Now, do an online search and see if you can find a replacement.
Panels that size are commonly more expensive then a new TV. If you can't find a replacement, you could consider removing all the boards etc. and selling those for parts. Then discard the broken LCD screen in an environmentally conscious manner. Take the money you got for the replacement parts and invest that in a new TV.
