I always start with seeing if when connecting an external monitor to the Laptops VGA output is the same or different to what you see when just via the Laptops screen. Reason is so that can narrow down to JUST Laptop screen or graphics chip, maybe even OR connection at cable either end, Motherboad or Screen. Is the Laptop turning on alright i.e. no frying, I assume it has dried out from when it got wet. localised to screen only or possibly inside of Laptop....Lights up with power, fan spins hard drive spins, right? If so try an external monitor.
