LG Electronics 60LA6200 60-Inch Cinema 3D 1080p Deal

 GatorJ (Florida): I purchased this TV to replace a 42" LG in my master bedroom (which replaced a 40" Sony XBR6). (FWIW, both of those TVs were purchased from Amazon. I have purchased six 40-47" TVs from Amazon and have never had any shipping problems or damage.) I originally started with the 42" version of this TV which was returned to Amazon due to some screen uniformity issues (more later). Due to the LA6200's thin bezel, the 47" worked in my space. I've had it for 4 weeks and I'm quite pleased with it overall. If I could give half stars, I would award it 4.5. I can't and on balance I thought it was more fair to give it 5 than 4.

Mathieu J. Champagne (Philadelphia, PA): Several have commented this TV is much thicker than some of the very thin models on the market. That is necessitated by the back lighting system LG utilized on this model line. All LED TVs have LCD panels. LCD panels, unlike plasma displays, are incapable of generating their own light...they must be back lit to produce a visible picture. The very thin TVs are edge lit. The LEDs are placed on the left and right or top and bottom of the panels and mirrors reflect the light onto the panels illuminating it to provide a picture. This configuration allows for a very thin TV, but there are compromises. The primary concern is called flashlighting. If there was a scene with a bright moon against a dark sky, the LEDs on the edge of the panel would have to light up the moon. As the light is being reflected, some displays will show a beam of light, not unlike the pattern of a beam of light from a flashlight, going from the edge to the illuminated object...in this case the moon.

Hans J. Storoy "Hans" (Cranston, RI, USA): The LG LA 6200 series are direct lit meaning the LED lights are arranged along the entire back of the panel and not just the edges. A full array back lit set has a great number of these LEDs mounted relatively close to the screen. Full array sets are found in the upper tier models and tend to be quite expensive. The direct lit system LG used utilizes less LEDs. To properly illuminate the panel, they are positioned farther away from the panel resulting in that thickness. Direct lit sets don't have problems with flashlighting, but they can have issues with dark screen uniformity and light bleed. Both my 42" and 47" LA6200s had/have light bleeding...the 47 far less than the 42. This is why I would deduct 1/2 star, if possible. The issue actually seems to be getting a bit better as the TV breaks in and I'm only seeing it on some dark screens, not all.
