Summary: I also own an LG 42lv355u and it will be two years old this Boxing Day 2013. Exactly the same as the previous post approx 18months old and exactly the same happened - screen crackled and stopped working then smoke started to come from the back of it. I won't be buying these again. Stay clear!
Summary: I was happy with this set until my area changeover to digital in June 2012. Until this time I had an abundance of Freeview channels all with a fine picture. Now since the June 2012 digital changeover disaster struck. Picture is unstable much of the time and has on screen blocking showing which makes it impossible to watch. It is a disaster. I have very few channels now.
