How to repair data display cable/connection after a spilled drink?

A few weeks ago a red flash got spilled on my macbook pro. (thank goodness the laptop was closed) I dried and cleaned everything as best as I could. Now when the laptop is open the screen flashes once and then goes black. Once I opened it and it had a perfect screen for a split second and then went black. I opened the lap top up and cleaned as much of the red flash off of everything under the back cover. Nothing changed. Though I did notice that everything was working on the laptop except the screen. I plugged an HDMI cable into the laptop and my screen appeared. I could use the keyboard and the mouse pad just fine. I could also use the HDMI plug, usb plugs, sd card plug with proper operation. (which are all on the same side) I researched that the data display cable is what controls the screen image. This cable also connects on the corner that received the most liquid. Is there a way to clean this cable and the connection to let it get proper connection? Is it possible to replace this cable or the connection? How much am I looking at in repairs?
