STOP! disconnect the MagSafe and open your system up following this guide: MacBook Pro 15" Unibody Mid 2012 Logic Board Replacement. Follow the first three Steps. Then jump down to Step24 using the image as a reference do you see any burn’t components? Do you see any tea stains? Your tea has shorted out some of the components we need to figure out whats damaged. If you think this is to much for you you’ll need to find someone to fix your system.
The tea probably damaged the logic board. You will want t open the device and look for any visible signs of liquid on the board. You can try to clean it off with IPA (>90%) and a soft brush. However, it may have shorted some components in which case this will have to be looked at by a repair shop that does micro-soldering repairs.
