I replaced my cpu with a new one and now my screen is black. The computer is working, all the fans and lights are on. Any solution?

The new and old CPU both require the same UEFI version to work, so that's not the problem. However, since you put old CPU back in, and still no signal, thats concerning. Have you tried removing CMOS battery on motherboard for a few minutes to try. Outside of this, I'd inspect all connections again remove and reinstall GPU and RAM sticks, and remove CPU to inspect socket for any signs of bent pins.
