Summary: I should start by mentioning that this is my first LED experience. I didn't do a lot of research before buying this product because it was really cheap compared to what it is offering (paid 690). It is a great looking TV. Colors look bright and vivid. Everything was perfect until I started using it more than 2-3 hours at a time. So after watching 3 hours of TV i decided to watch a movie from my computer. So I plugged it in and turned the lights of and started watching.
