I have a Samsung 27 inch flat screen large back TV HDTV. I paid about 550 in 2007 for it. It has stopped working. When you turn it on it won't get a picture. The screen stays back and the on/off goes off in about 30 seconds. What is wrong with it? Is it worth trying to fix it. The TV I want is about $450. I am waiting for the smart Tv's to get cheaper and the 4G TV's to get cheaper. I want this to last about 3-4 more years. Do you think that this could be fixed for less than $200.
