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've owned this television for a year now and am really pleased with my selection. My previous television was a smaller (24"?) CRT which I had owned for 10 years. I'd stuck with it for years, partly because I had no compelling reason to upgrade, partly because I was concerned that a larger screen would unavoidably mean worse apparent picture quality for standard-definition broadcast TV.
Summary: Received this lovely looking tv today to find it had been dropped in transit and a 1inch gauge in the tv from the stand was the result... Amazon no questions asked (apart from the obvious) have issued a replacement tv which will be with me within 48hrs and the other tv gets collected tomorrow....
Summary: Bought this TV from Amazon about 6 months ago and all is well. Fantastic picture quality and brightness and contrast is unparalleled in comparison to my old Phillips LCD. I have recently mounted it onto my living roomwall and thankfully it looks awesome, as it's so thin. Be warned though, the sound quality from the built in speakers is woeful and you will need speakers or home cinema. I've bought a sound bar, which works great. This is truly a bargain!
