is it warm or hot to touch? no sticking defrost timer? if not then check the cold control tempeture thermostat, the thermistors, and the door seals, lastly may have a coolant problem, do any of the back copper tubes to the compressor feel cold to the touch
i have had this problem also but not with it getting wet. i have bought a new digitizer (touch pad which you can get of amazon by looking for a lgkc910 digitizer) i am yet to have it replaced but if it doesnt come down to that i think it have had damage to the motherbord or needs software updates
You will need to remove the grill. Unplug the unit, Then on the control board you will see 4 wire with a black connector. Unplug that and plug it in 4 or 5 times. Make sure you dont bend the pins. Then plug the connector back in and plug unit back in. You should have better response on the display. They have a special coating and the pins needs to be cleaned this way.
Those control boards are sort of flakey and any kind of power surge, etc. can really goof them up. If you check under the very bottom of the fridge there should be a technical sheet taped up to the underside in a plastic bag. Take that out and read it to see if there is a test reset you can do before replacing the board.
