LCD Display showing lines after the power supply short circuited.

My Desktop PC has a Philips LCD that stopped working last night. The power supply short circuited at some point and I didn't know about it. Lines started appearing across the screen and it took me about 3-4 minutes to figure out what happened. Now when I turn on the display, lines appear across it. Is my LCD damaged for good? Is it repairable? If yes, how may I repair it?
