i have replaced my lcd 2x before and nothing went wrong but this time its not truning on

what is the prblem? did the connector got burned orsomething?

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 :(

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.
