Diid you try to clean the logic board with isopropyl alcohol (90% or higher?) If not I would try to clean the connector areas and see if that allows the LCD to function. If it does not I would try cleaning the whole board and see if that fixes the issue.

Did you replace the LCD twice BEFORE it has come into contact with liquid? If so then the LCD connection has probably suffered liquid damage and won't work ever again :(
