Blank screens are caused by a number of problems:
1. backlight broken - shine a bright light at an angle to the screen if a faint imaged is seen then it's either the backlight or the inverter that powers the backlight.
2. inverter - see above
3. cable (wires) from the motherboard to the screen
4. broken LCD

all of the above require a qualified tech to diagnose and/or fix. Often it costs more to fix than to buy a new laptop.

Good Luck

yes the motherboard may have been damaged by the liquid. You can remove the hard drive and connect it to an external USB adapter to make it into an external hard drive for another computer.

Good Luck
