Summary: I recently purchased a 42LH50. I researched this class of TV extensively and based on features and the reputation of LG, as well as my own experience with other LG products, I chose to purchase this TV. I got it home, fired it up and marvelled at the quality of the picture. It was incredible and the 120MHz scanning was awesome. Everything was great until the TV turned itself off after about 5 minutes. I thought maybe it was a setting that I needed to change.
