Have TV Questions? Ask a TV Technician
The set is a 2008 model. It should last longer.
8 years isn't bad for the half life of an old TV. But who says your TV can't be fixed? All you need is to look at the TV's model, the version if it's a Samsung..and see if the TV's menu still appears on the screen, or you see the TV screen still glow when it goes black. Every tech on here will ask those questions outright.
