Curbside let down could use some advise

So one night curb shopping a found a 32in magnavox flat screen HDTV. I get it home an it works GREAT because I could really use it. It has a dark spot in the middle of the screen kinda like a shadow but u can't notice it unless your looking for it. 2 week later it just cuts off the red light on the front isn't even lit. If I unplug it for a while then hook it up the red light comes on so I hit power black screen lights up with the channel in the corner but then cuts right back off. What do you guys think is it fixable? Is it worth getting fixed?or should I pull the boards out an scrap it? Thanks
