42” Class Full HD 1080p 240Hz LCD TV (42.0” diagonal)

42LH55

  • LED performance and a stylish, color-infused design set a new standard in home entertainment. Unlike other LED HDTVs that use "edge" lighting, LG's LH90 uses a full array of LED backlights which employ a local dimming technology for precise picture control, resulting in deeper blacks, a wide color gamut and smooth motion for a more natural picture. Available in July.

Answer: 
This television does not have any network access available. In order to obtain all the connectivity that is available on our Smart TVs, including Wi-Fi connectivity, without having to obtain an entirely new TV or player, it is recommended to obtain the Smart TV Upgrader, model ST600 which will allow the Smart TV features which are available through the LG Apps Store. Information about this device can be viewed on our website at http://www.lg.com/us/tv-audio-video....

There is a sound (like sound of start up of Windows in computers) or like short melody that goes on every time we turn on the tv. I need to turn it off or at least reduce the volume to the minimum

Answer: 
We appreciate your interest in this LCD television. The USB port is not designed to provide a high amount of electrical current. According to page 60 of the owner’s manual, please connect a separate power cord to any USB device requiring more than 0.5A; otherwise, the device may not be recognized.
