I sent my laptop in to be serviced under warranty because the keyboard would not work. was denied service because of water damage but now my screen doesn't work, can someone help

Water can destroy a laptop or any other electronic device. Chances are that the water sat underneath the keyboard and flowed onto the motherboard where it dried causing corrosion and damaging the motherboard permanently. You could take the laptop to a repair shop and they could give you a repair estimate. Of course, you will have to pay for this repair. If a liquid is spilled on a laptop in the future, immediately open it and turn it upside down. This allows the liquid not to hit and pool on the motherboard, or in a keyboard
