Living Room - Big Screen TV Problems! Yikes!

So I'm watching tv in the livingroom last night and for no reason it just clicks off! Ok no problem I'm thinking. I have to get up and turn it back on but it will be worth it. So I click it on and it just goes right back off again! So now I'm thinking "Great! Now I need a new big screen!" I'm hoping the problem will go away because I just cannot afford another big screen TV.

Since I'm such a pack rat I found the original receipt and found out that it was purchased back in 1997. So I'm begging everyone that has a big screen older than this to let me know that this is just a temporary problem and that all will be well again!
