I was closing my chromebook harshley and i didnt realize one of my earphones was on the keyboard which resulted in a cracking sound and when my chromebooks off there is no visible sign of a crack but when its on theres a bunch of colored lines on half the screek and a crack that looks like i shot it with a airsoft gun what can be done about this. Its still fuctioning from the side i can see.
Sounds like your LCD is cracked. Try replacing the LCD screen.
