My kids threw their WII remote at the 40'' LCD screen TV

The short answer is a cracked LCD is not worth repairing.

Sorry this tv can't be fix acept replaced the whloe picture screen panel itself,the tvs screen panels are in of the limited production by the tvs industries,only can buy picture screen panel from the tvs themselves and it 90% important to the tv,will cost u the same as a new tv to get picture screen replaced.Sorry doesn't worth as a whole tv anymorre the tv now only worth as salvages tv for it electronic boards for spare parts for other tv,that it.

The LCD Screen is damaged beyond repair. Cost to replace TV is cheaper than repair.

This TV may be totaled as the replacement screen can be as much as the TV itself! Sorry...start searching for a new TV!

You need new LCD panel, very expensive!

It is broken,The outside is a Polorised film.Like window tint,It is repairable,New LCD screen.But may be cheeper to buy a new TV. GET A EXT.WARENTY!!! will not cover accidents but the new tv's do break alot,and are expensive to repair.
Buy a name brand, NOT RCA "junk" Just a name
no longer a company. Samsung,Panasonic,Sony. If you want to support the USA buy another Sharp. Still a great TV. And made in America. NOTE they make after market screen protectors. GOT KIDS? GET ONE. :) Or even a piece of plexie glass if cash is tight. Hope this helps.

This can be repaired only by replacing LCD Panel.
Contact closest Sony Service Center for LCD Panel estimate.

We played Wii sports and fit for few hours than tv started to flicker and change colors to green and black and white. We shut down Wii and not TV screen doesn't show any picture. The power is there and the sound... but the screen is just blue. Any one experienced anything similar?

Without a model number I gather the TV she threw the remote at is a LCD tv? If so look at replacing the set as the LCD panel is now damaged and usually cost more that what a replacement set will. There is no fixing a damaged LCD panel.

Get a broken TV same make, replace the back panel with the serial numbers and get your warranty to replace the tv.
