    So first, you should go back and re-check everything you disconnected to clean it and make sure everything is connected and seated well. Next, first step in troubleshooting the screen is to connect an external monitor to the laptop and boot it up. If you get video on the monitor but not the laptop you have a problem with the laptop screen itself. If you get no video on the monitor or the laptop you probably have a bad video card, which would be the integrated video card on the motherboard not the GPU.
