INFO + MENU + MUTE + POWER ON

Then you should get access to Service Menu.

The last item says: RESET

This will do a reset to the TV.

Make no harm.

WARNING: If when on service menu you feel tempted to "screw" on anything FIRST take note on ALL you change! You can compromise the TV ...

SOURCE: CRACK LCD TV SCREEN

I had one broken a few months ago. I got a couple quotes.. it was about $200 less then a brand new one. I'd just buy a new one.
For the new TV I'd pickup a screen protector for it. My son threw a toy at my TV the other day and I nearly had a heart attack from the flashbacks. Thank God I picked up one of these a few weeks earlier. It stopped it. LCD screens really break easily as you know. http://www.tv-armor.com
