Problem with My Lcd Tv?

its a JVC 46" and I left it on last night, and left my cable going. Its never had a problem before and I normally do this alot, but I came out about 20 minutes ago, and saw that its no longer displaying a yellow color….the blue seems washed out, and look HORRIBLE.

What happened? How do I fix it? I can add additional info if anyone needs…..

Leaving your tv on is waring it out, this is probably a good example as some component has failed.
