Is there a fix for tv discoloration?

hey guys!,

I have a Toshiba 26AV502R Tv and it was working good for a while then it kinda become discolored and a little whited out, i need help if there is a fix or not!

You can find replacement backlights for it on ebay but honestly I would just get a new TV since they have come down a lot in price over the years.
