Why won't my TV stay on?!?!?

We have a 32" Magnavox television. We have had it about 15 months... the other night, when we turned it on, the picture was weird...the color was wrong and it had lines going through it...the volume did not work and then, within 5 seconds, the TV shuts off...anyone have any idea what that might be?? Thanks show more We have a 32" Magnavox television. We have had it about 15 months...
