Unplug the system and disconnect the battery from the system board. Hold the power button for 30 sec.
Disconnect and reconnect the LCD cable from the system board (both ends - screen and mainboard). Plug back in and see if the system will recognize the LCD.
If it will still not, hold the D key through powerup. The system will initiate a series of self-test screens. If you don't see those, the screen needs to be replaced. If you do, it suggests the problem is with the system board, not the screen.
Hi @NixaTechDude thank you for the clarification that "I am a computer tech and this is what I do is work on pc and laptops. I have to get this fixed for my client." you are using the free advice from volunteer users in the course of your business. @DELL-Cares
As a business I will use any and all help to get my customers back up and running again. But I also run an honest tech support company. If I damage a customers equipment I pay for the repair. I will also ask for help something is not making sense to me. I may just need to send it to Dell and have it repaired if I can not find the problem. And that will be on my dime sense I was the one working on it. I was just looking to see if anyone else has had this problem before.
I don't see how. After the rear piece was removed so the the bottom plate can be removed to get to the battery the laptop stayed closed the whole time. I checked the cable and it is fine. I just want to if see if anyone else has had the same problem before. Or if there is something else I should be looking at for the cause.

That is an LCD failure as per this support page. Is it possible that during the battery replacement the LCD cable was disconnected or damaged?
