I need some advice. I have a samsung 40 inch led TV I purchased in DEC 2012. when ever I am watching something with light colors on the screen you can see these 4 dots two on top and two on bottom. It looks like it might be some kind of image burn in. I talked to samsung and they send me an e-mail with a bunch of info about sending it in for repair. Do you think I should send it in ? If I do send it in I will have to pay for shipping and loose my TV for a few weeks. I am just worried they might not be able to fix the problem and just send back my TV the way it is.
